HOW EXPERIENCED PHENOMENA RELATE TO THINGS THEMSELVES: KANT, HUSSER=
L,
HOCHE,
Max Velmans, Department of Psychology, Goldsmiths, University of
London, New Cross,
Phenomenology and the Cognitive Sciences, 2006 (in press)
Abstract. What we= normally think of as the “physical world” is also the world as experienced, that is, a world of appearances. Given this, what is the reality be= hind the appearances, and what might its relation be to consciousness and to constructive processes in the mind? According to Kant, the thing itself that brings about and supports these appearances is unknowable and we can never gain any understanding of how it brings such appearances about. Reflexive monism argues the opposite: the thing itself is knowable as are the processes that construct conscious appearances. Conscio= us appearances (empirical evidence) and the theories derived from them can represent what the world is really like, even though such empirical knowled= ge is partial, approximate and uncertain, and conscious appearances are species-specific constructions of the human mind. Drawing on the writings of Husserl, Hoche suggests that problems of knowledge, mind and consciousness = are better understood in terms of a “pure noematic” phenomenology t= hat avoids any reference to a “thing itself”. I argue that avoiding reference to a knowable reality (behind appearances) leads to more complex explanations with less explanatory value and counterintuitive conclusions—for example Hoche’s conclusion that consciousness is not part of nature. The criti= cal realism adopted by reflexive monism appears to be more useful, as well as b= eing consistent with science and common sense.

------------------------------------
In everyday life we take = it for granted that the world that we see, hear, feel, smell and taste around is t= he real world—and we normally think of it as the “physical world.” However, the wo= rld as perceived is in many respects very different to the world as described by modern physics. This raises an immediate and perennial question: how does the world as perceived relate to what the world is really like? Or, to put in a Kantian way, how does the phenomenal world relate to the “thing itself”?
In Velmans (2000) I have developed a reflexive monist approach to answering this question, and given that aspects of my analysis are often misunderstood or misreported it has b= een a pleasure for me to see the careful and largely accurate account of some of these aspects given by Hoche (this issue) in the first part of his paper (<= span style=3D'background:yellow;mso-highlight:yellow'>sections 1 to 6.3 or pages= x to y?).
Given =
that the
following elaboration of my work can be read conjointly with Hoche’s
paper, I will not repeat the analysis of reflexive monism that is given the=
re.
Put in the briefest terms, the reflexive model of perception shown in Figur=
e 1
shows in microcosm how reflexive monism differs from dualism and
reductionism. As shown, light rays reflected from the sur=
face
of an entity in the world (a cat) innervate the visual system and initiate =
perceptual
processing. Afferent neurones, and cortical projection areas are activated,
along with association areas, long-term memory traces and so on, and neural
representations of the initiating event are eventually formed within the
brain—in this case, neural representations of a cat. But the entire causal sequence doe=
s not
end there. S also has a visual experience of a cat and we can ask S what th=
is
experience is like. In this c=
ase,
the proper question to ask is, “What do you see?”=
=
[1]=
According to dualism, S has a visu=
al
experience of a cat “in h=
er
mind”. According to
reductionists there seems to be a phenomenal cat “in S’s
mind” but this is really nothing more than a state of her brain. According to the reflexive model, =
while
S is gazing at the cat, her only visual experience of the cat is the cat s=
he
sees out in the world. If=
she
is asked to point to this phenomenal cat (her “cat experience”),
she should point not to her brain but to the cat as-perceived, out in space
beyond the body surface. In t=
his,
the way that the cat appears to S is similar to how it appears to E—a=
s a
perceived entity out in the world, albeit viewed from S's perspective rather
than from E's perspective. [2] In short, an entity in the world is
reflexively experienced to be an
entity in the world.
It is, of course, impossible to illustrate =
all
the complex relationships that obtain between experiences and the things th=
at
they are experiences of, along with the relationships between the
“observations” of an external observer trying to make sense of =
what
is going on in S’s mind/brain and the “experiences” of the
subject, in such a simple two-dimensional, schematic figure. Unravelling th=
ese
relationships takes up three chapters (chapters. 6, 7 and 8) of Understanding Consciousness. Given this, it is not surprising t=
hat in
note 11, Hoche admits to being a little confused about the different ways t=
hat
I refer to the cat in Figure 1 (throughout the book) depending on the
relationship and the perspective under consideration. For example, viewed f=
rom
the perspective of an external observer E, the cat is the object he can see=
in
the world that causes S’s
subjective experience. However, viewed from the perspective of the subject =
S,
the perceived cat is what she
experiences. S can’t perceive the causes of her current experience for
the reason that the causes of perception operate preconsciously—and o=
nce
she experiences the cat, these causal antecedents of her current perception
have already operated. So, vi=
ewed
from S’s “subjective” perspective, the perceived cat is t=
he perceptual effect.
Things start to get even more complicated o=
nce
one accepts that E is also an
experiencing agent, with his own subjective perspective. Although he
conventionally treats the cat t=
hat he
can see as the cause of what S experiences, the cat’s visible propert=
ies
result from his own preconscious perceptual processing, just as they do for=
S.
Strictly speaking therefore, it is not the cat that he experiences that is the initiating cause of S’s perceptual
processing, but the entity (or cat) itself.
There is far more to be s= aid about all this, but given that it has all been elaborated elsewhere, and gi= ven that Hoche largely finds his way around the complexities, I won’t rep= eat this here. Rather, I will focus on the one issue that most concerns Hoche—how best to think about the relation of experiences to the thin= gs that are experienced.
How experiences relate to things themselves: resemblances to Kant
Hoche rightly describes t= he analysis that I give of this issue as “quasi Kantian”. In making a connection with aspect= s of Kantian thought (in Velmans, 2000, chapter 7), my intent was both to acknowledge the priority of his work and to take the opportunity of placing= my own work in an appropriate context. Given this background, it is easier to understand and assess this aspect of reflexive monism, not just in terms of major similarities to Kantian thought, but also in terms of major points of difference. Put very briefly,= the main points of similarity, as I see them, are
1. Kant argued that the “physical world=
221;
that we experience consists of phen=
omena.
That is, “External objects (bodies) ... are mere appearances, and are,
therefore, nothing but a species of my representations.” (Kant, 1781,
p346). The brief description =
of the
reflexive model of perception given above makes the same point, although it
gets to it from a different direction.
2. Kant argued that these appearances are shap=
ed
by pre-existing categories of the mind, and I similarly accept that experie=
nced
phenomena are at least in part a construction of perceptual and
cognitive processes that operate in the human mind/brain.[3]
3. I accept (as Kant did)= that human knowledge is constrained by the organs of knowledge (by the perceptual and cognitive processes that operate in the mind/brain).
Consequently
4. It is a mistake to con= fuse the phenomenal world constructed by the mind/brain with the world itself (vario= usly termed the thing itself, the thing-itself, the thing-in-itself, reality its= elf, nature itself and other usages).
Indeed I think it worth s= tressing that these basic points have far older roots, in elements of Hindu and Budd= hist thought and in the philosophy of Ancient Greece.
How experiences relate to things themselves: differences from Kant<= o:p>
However, unlike Kant, I a= rgue that the thing itself is knowable= i>, and given the fundamental nature of this difference, Hoche thinks that “it may seem doubtful whether Velmans was well advised referring to K= ant at all” (p11?). He may be right.
According to Kant, the se=
paration
of the phenomenal world from the thing itself produces a clear separation
between what can and cannot be known.
One can know and explore the nature of the phenomenal world, and
I do not wish to=
skate
over the fundamental problems raised by Kant’s analysis of how the
mind’s own nature constrains what it can know. Kant is surely right to point out =
that
we cannot have knowledge of “reality” in a way that is free of =
the
limitations of our own perceptual and cognitive systems.[4] We cannot make observations that a=
re
“objective” in the sense of being observer-free, or have knowledge that is unconstrained by the way that our
cognitive processes operate. =
Our
knowledge is filtered through and conditioned by the sensory, perceptual and
cognitive systems we use to acquire that knowledge. Given this, we cannot assume that =
our
representations provide observer-fr=
ee
knowledge of the world as it is in itself.
Nor is empirical,
representational knowledge certain<=
/i>
knowledge. For representational
knowledge it is easy to see why this is so. Whether the representations be in humans,
non-human animals or machines, a representational system can only have (acc=
ess
to) its own representations of that which it represents. Consequently, a
system’s representations define the limits of its current knowledge.
Lacking any other access to some ultimate reality or “thing
itself,” there is no way that a representational system can be certain that its representations a=
re
accurate or complete.=
=
[5]=
Uncertainty ther=
efore
appears to be intrinsic to
representational knowledge. Kant’s view that the thing itself is unknowable is nevertheless extreme.
Knowledge that is uncertain and conditioned by the perceptual/cognitive
processing of a knowing agent is still knowledge. So even if one accepts th=
at
knowledge of what the world is really like can only be partial, species-specific and tentative, it=
does
not follow that the world itself is unknowable. Although it is logically
possible that the world that we experience is entirely illusory (along with=
the
concepts and theories we have about it), the circumstantial evidence against
this is immense. We necessarily base our interactions with the world on the
experiences, concepts and theories we have of it and these representations
enable us to interact with it quite well. Kant’s extreme position is =
in
any case self-defeating. If w=
e can
know nothing about the
“real” world then no genuine knowledge of any kind is possible whether in philosophy or science –=
; in
which case one cannot know that=
that
the thing itself is unknowable, or anything else.
Interpreted in Kant’s way, a theory of
knowledge based on representations grounded in an unknowable
“thing-itself” is also internally inconsistent. If the appearances of the external=
world
are not representations of some=
aspect
of the thing itself, then these appearances cannot really be representations, as there is nothi=
ng
else for them to be representations of.&nb=
sp;
Conversely, if they are
representations of some aspect of the thing itself, the latter cannot be
unknowable.=
[6]
Similarly, if we can “n=
ever
acquire any concept” about what the world is really like, then our
concepts and theories cannot be about anything “real.” Converse=
ly,
if these do provide a measure of knowledge about how things really are, the=
n it
cannot be true that of the thing itself “we can have no knowledge
whatsoever.”
In sum, although there are no empirical
certainties, one is ultimately left with a pragmatic choice: either our
representations of the world tell us nothing about it (in which case all of=
our
so-called knowledge must be groundless) or we adopt a form of critical realism in which our perc=
eptual
representations are taken to represent real things in a species-specific,
sometimes useful, albeit uncertain way.&nb=
sp;
I would argue that the latter provides a sounder foundation for a th=
eory
of knowledge. Broadly speaking, it is also the view adopted within modern
science.
Einstein & Infeld, for example, admit t=
hat
“Physical
concepts are free creations of the human mind, and are not, however it may =
seem,
uniquely determined by the external world. In our endeavour to understand
reality we are somewhat like a man trying to understand the mechanism of a
closed watch. He sees the face and the moving hands, even hears its ticking,
but he has no way of opening the case. If he is ingenious he may form some
picture of a mechanism which could be responsible for all the things he
observes, but he may never be quite sure his picture is the only one which
could explain his observations. He will never be able to compare his picture
with the real mechanism and he cannot even imagine the possibility of the
meaning of such a comparison.”
(Einstein & Infeld, 1938, p31)
It is nevertheless implicit that, for Einst=
ein
& Infeld, there really is a
“closed watch” and that the “moving hands” and
“ticking” tell us something (albeit uncertain) about its nature=
on
which our theories about it can be based. Reflexive monism adopts a similar “crit=
ical
realism”.
The re=
flexive
model makes the conventional assumption that causal sequences in normal
perception are initiated by real th=
ings in
the external world, body or brain.[7] Barring illusions and
hallucinations our consequent experiences represent
those things. Our concepts and
theories provide alternative representations of those things. While neither our experience=
s nor
our concepts and theories are t=
he
things themselves, in reflexive monism, things themselves remain the true objects of knowledge.
Although this po=
sition
is neo-Kantian in some respects, the role that the “thing itself̶=
1;
plays is very different. Rather than the thing-itself (the “real̶=
1;
nature of the world) being unknowable, one cannot make sense of knowledge
without it, even if we can only know this “reality” in an incom=
plete,
uncertain, species-specific way. &nbs=
p;
Conversely, if the thing itself cannot be known, then we can know
nothing, for the thing itself is all
there is to know.
Nor, in reflexive monism,= can a sharp division be drawn between the phenomenal world and the thing itself that gives rise to it. Rather, both our mind/brains and our phenomenal experiences are embedded in, and manifestations= of the reality that gives rise to and supports them—which has obvious co= nsequences for what that reality must be like. Even if we cannot know that reality or thing itself as it is in itself, completely or with certainty, we can say t= hat it must have the power to give rise to the particular configuration of mind/brain states and phenomenal experience that we can in principle observe and investigate (for example, with the technologies of neuroscience).
And even without such spe=
cialised
technologies, we can, with reasonable confidence, say something about how mind/brains relate to phenomen=
al
experiences. Broadly speaking, conscious experiences are both produced by
mind/brains embedded in and interacting with their surrounds, and represent
those surrounds or, in cases of self-reflection, represent their own operat=
ions
(in the form of conscious feelings, thoughts, dreams, images and so on).
In sum, knowledge is po= ssible for the reason that both the organs of knowledge and the knowledge that they produce are manifestations of the same underlying reality, shaped by the constraints of evolution—and more to the point, knowledge in the broa= dest sense, is self knowledge (knowledge of the thing-itself by knowing creatures that are its own manifestations). From a reflexive monist point of view, we literally participate in the process whereby the thing itself knows itself.=
Things themselves versus noematic phenomena in the Husserlian sense=
According to Kant, phenomenal representations cannot be taken to represent what =
the
world is really like because the thing itself is unknowable. According to
reflexive monism, useful phenomenal representations can be taken to represent what the world is really like, because
the thing itself is knowable, albeit in an uncertain, partial, approximate,
species-specific way. According to Hoche, neither of these views has a secu=
re
basis. Instead, the relation of phenomenal representations to their objects
should be understood as the relation of ‘noematic phenomena’ to=
the
‘noematic objects themselves’ that they represent (or
‘intentionally relate’ to), a terminology and conceptual system=
that
he adapts from the transcendental phenomenology of Husserl.
If I understand it rightly, the point of
departure for Hoche’s analysis is a fundamental point on which we
agree—that in terms of phenom=
enology,
there is no difference between a percept of an object and the object as
perceived (see the simple description of the reflexive model of perception
above). In my own analysis I
nevertheless stress that there is a causal sequence in visual perception: l=
ight
rays reflected from the surfaces of an object
in the world activate processing in the visual system that eventually
results in a percept of that object=
,
which is (reflexively) seen as =
an
object in the world. Consequently, although no phenomenological distinction=
can
be drawn between a “percept of an object” and the “object=
as
perceived”, a distinction can be drawn between these terms in two oth=
er
ways: (a) these phrases direct our attention in different ways—the ph=
rase
“object as perceived” foregrounds or focuses attention on the object that is the initiating caus=
e of
perceptual processing, while the phrase “percept of the object”
foregrounds the resulting percept=
i> or experience. (b) if we are interest=
ed in
what the object that initiated processing is really like (as opposed to wha=
t it
looks like) we can investigate it more deeply (e.g. with physical instrumen=
ts),
thereby (in my terms) penetrating more deeply into the nature of the object=
(or
thing) itself. As such investigations proceed we may come to have very
different views about the nature of the object (including, for example, qua=
ntum
mechanical ones), even if the object itself does not change. Consequently, =
as I
point out in Velmans (2000), the thing itself may also be thought of as a
“reference fixer” required to make sense of the fact that we can
have multiple investigations, experiences, concepts or theories of the same thing.
Drawn to Husserl’s transcendental phenomenology, Hoche rejects the suggestion that there must ultimately be some “thing itself” that initiates perceptual processing which the resulting percept, in turn, represents. He nevertheless accepts that there= must be an object that is experienced. Consequently he tries to make sense of the relation between an “object as perceived” and a “percept = of that object” purely in terms of phenomenology, by arguing that with a little bit of further work on distinction (a) above, one can do away with distinction (b). According to him
“..the relation that obtains between those multifarious experiences and the one and= same thing of which they are exper= iences can be aptly described in terms of ‘transcendental phenomenology̵= 7;, especially in the ‘purely noematic’ version of it which I have developed elsewhere. On the f= ace of it, the defining characteristic of such a ‘purely noematic phenomenology’ (or ‘pure noematics’) is the very point Velmans tries to drive home, namely, the assumption that, contrary to first appearances and engrained prejudices, we are not genuinely justified in making a distinction between a given subject’s conscious experience of an object at a certain moment in time and this obj= ect as experienced by that subject at that moment. Unlike Velmans, however, the advocate of such a purely noematic view of consciousness takes the terminol= ogical distinction between ‘the object (experienced)’ and ‘the object as experienced’ to= be highly significant. A simple case in point is again Velmans’s example= of my own seeing a cat. When I see a cat, the relevant conscious experience, to wit, my visual perception of it – or, speaking more down to earth: my seeing it – should again be considered to be the cat as seen, but unlike Velmans by these words I suggest one ought = to understand, not simply the cat (which is) seen, that is, the cat as a Kantian ‘phenomenon’, = but the cat as, qua, or in its capacity= of being seen by me at the given moment in the given particular way, that is, = as a ‘(noematic) phenomenon’ in the Husserlian sense. (p )
In footnote 16, Hoche goe= s on to explain that “Such noematic ‘phenomena’, or ‘object= s in their capacity of being perceived’ by me at a certain moment in time, may be well compared to= a bunch, or bundle, of rays or straight lines intersecting each other in one = and the same point, which, for its part, would then correspond to the noematic ‘object itself’ – or, I take it, to what Velmans (2000: 1= 63) calls the ‘reference fixer’”.
Hoche goes on to explain t= hat
“ The position just outlined is confirmed by the fact that the =
cat
which I see and the cat qua now=
being
seen by me under specific circumstances are incompatible in that they can be
given to me neither simultaneously =
nor in
one and the same cognitive attitude. When I focus my attention or inter=
est
on the latter, i.e., on my present visual cat phenomenon (in the noematic s=
ense
of the word), I have to do with the cat in,
or with, its present mode of
subjectively appearing to me from a certain point of view, in a certain
distance, and under certain lighting conditions; and the slightest noticeab=
le
change of one of these parameters suffices to make my cat phenomenon shade =
off
into another one out of a continuum of visual phenomena which are related to
each other in a specific though familiar way which permits us to interpret =
them
as belonging together or intentionally referring to one and the same cat. B=
ut
when I focus my attention or interest on this cat itself, i.e., on the cat =
which I see, then I have to do wit=
h an
objective animal to the total exclusion of the continually changing modes of
its subjectively appearing to me. So the objects which I perceive and the objects qua being perceived by me characteristically differ in that the
latter are concrete entities in=
which
every detail counts whereas the former are mere abstractions – abstractions, however, with which for at l=
east
two reasons in everyday life we have to content ourselves: First, it is principally impossible to identify=
and
discriminatingly name ‘each and every single segment out of a
continuum’ of noematic phenomena shading into, and in this sense
belonging to, one another (e.g., my visual phenomena of, or intentionally referring to,
one and the same cat sitting in front of me); and second, even if it were possible to do so, adopting s=
uch a
reflective attitude of heeding the details of phenomenal concretion as our
standard attitude would hopelessly overburden us. Rather, in everyday life =
we
have to adopt a straightforward attitude in which we abstract from those details, or ‘look through’ them, and concentrate exclusively upon the things
themselves. Correspondingly, I consider the reflective attitude to be a
cancellation or suspension of that everyday abstraction, i.e., an uphill
attempt to take the conscious phenomena in their full concreteness. In
principle – scil., once we have acquired the necessary skill and prac=
tice
– it is easy to switch to and fro between the straightforward attitud=
e,
centered on the things themselves, and the reflective attitude, attending to
the wealth of phenomenal continua; but it is out of the question to focus simultaneously on a thing itself a=
nd on
an element of a phenomenal continuum. Hence the different fields of abstract things themselves and of =
concrete noematic phenomena, exclu=
ding
each other to the point of being well comparable to ‘incompatible
quantities’ of microphysics, may be taken to define the correlative
concepts of objectivity and subjectivity. For this reason I consider
subjectivity, i.e., respectively my own conscious experience, to be so
different from all objects in the natural world that we may downright call =
it
‘the negative’ of objective reality. In this sense I cannot but=
deny that consciousness is a part of n=
ature.”
(p )
I have to confess that =
I find
some parts of this passage difficult to unravel, and the motivation for som=
e of
it difficult to understand—particularly towards the end. But I will t=
ry.
To take the easy bits fir= st, I can understand the desire to understand everyday phenomenology and its obje= cts in a way that avoids reference to an unknowable Kantian thing itself. I grant that it is possible to have an abstract sense of an ‘objective’ cat that somehow underlies the various views that we can have of it (under different lighting conditions, = from different angles, and so on). I also would defend a careful, open-ended investigation of an object’s phenomenology to discern what might be revealed about it with careful attention (and which might not have been evi= dent at first glance). That is all= part of the European phenomenological tradition—and I have defended a crit= ical version of that tradition in ways that I do not have space to develop here (c.f. Velmans, 2006a).
I have to confess, howeve=
r, that
I do not find Hoche’s attempt to compare our knowledge of cats themselves (or of other entities, events=
and
processes themselves) to the intersection of their phenomenal appearances v=
ery
useful. Nor, other than the d=
esire
to be as “concrete” as one can, is the motivation behind this
“purely noematic” analysis apparent. The intuition that there i=
s a
reality lying behind phenomenal appearances that is neither entirely manife=
st
in appearances, nor a simple abstraction derived from their convergence, has
been an enduring feature of philosophy and empirical investigation for over
2,500 years. It was clear, for example, in the rationalist philosophy of an=
cient
Not surprisingly, Hoche̵=
7;s
attempt to force nature and the ways in which it can be known into such a
simple mould leads to some counterintuitive conclusions. For example, towards
the end of the passage cited above, Hoche decides that “abstract things themselves”
defined in his “purely noematic” way constitute objectivity,
whereas “concrete noematic
phenomena” constitute subjectivity. This is another issue that I do n=
ot
have space to pursue here—other than to say that in my understanding =
the
relations between subjectivity, intersubjectivity, and
“objectivity” are far more complex than this (cf Velmans, 1999,
2000 chapter 8, 2006b). One cannot make sense of them without, for example,
understanding how “private” events relate to “public̶=
1;
events and how first- and third-person perspectives relate to each other. Hoche’s analysis also leads =
him to
“deny that consciousness is a=
part
of nature.” Few
contemporary students of consciousness would agree with him, as this would =
block
its investigation by any natural means. Reflexive monism asserts the opposi=
te: both our mind/brains and our phenomenal experiences are
embedded in, and manifestations=
of
the reality that gives rise to and supports them, making consciousness an
integral part of nature that can be investigated by a combination of first-=
and
third-person techniques.
Hoche goes on to admit = that
By de= nying that consciousness is part of nature, “… I may seem to manoeuvr= e myself in flagrant opposition to all serious contemporary scientists and philosoph= ers, including even the most ‘soft-line’ exponents of non-reductive = and non-physicalistic theories of consciousness.” He then tries to justify his sceptical doubts by recourse to a form of ‘semi-behaviourism̵= 7; when he notes that as far as he can know the experiences of his fellow men “..their conscious experiences are nothing but stretches of relevant situated behaviour, linguistic as well as non-linguistic. The reasons why I= think I ought to defend, if only in this strictly limited version, a kind of old-fashioned behaviouristic ‘nothing-buttery’ are easily state= d. First, nowadays only few people are prepared to admit that we have, in one = way or other, an immediate access t= o another person’s subjective experiences. Second, as we had occasion to learn = from Frege, Waismann, and Wittgenstein, it does not even make sense to say that somebody else has, or probably = has, or possibly has, or possibly ha= s not, conscious experiences similar= to my own, from which it follows that all traditional and modern ‘inverted spectrum’ speculations, and even recent reasoning about ‘inverted’, ‘absent’, ‘fading’, and = 216;dancing qualia’ […] lack a sound foundation [...]. Third, which is but a corollary, the attribution of consciousness, in the sense of subjective experiences, to other people and hig= her animals is neither verifiable nor falsifiable and hence not even open to pu= rely empirical hypotheses. And fourth, as we speak about ourselves and our fellow-men in strictly the same interpersonal terminology of ‘psychological’ (or ‘psychical’) verbs and hence are definitely disinclined to deny the existence of ‘other minds’, = the best option which I think we have is to identify another person’s perceiving, sensing, feeling, wanting, intending, acting, and the like, with precisely that stretch of his or her situated behaviour on the strength of whose observation we have a right to assert that he or she is perceiving, sensing, feeling, wanting, or intending something, or acting in such-and-su= ch a way, and so forth.” (p )
Given behaviourism’s traditional opposition to incorporating conscious phenomenology into psychological science, or even admitting to its existenc= e, Hoche’s transcendental phenomenology and his ‘semi-behaviourism’ make strange bedfellows. I have given a bri= ef history of behaviourist approaches to consciousness along with an evaluatio= n of their strengths and weaknesses in Velmans (2000, chapter 4) and little purp= ose will be served by recapitulating this here. Once again, however, Hoche trie= s to achieve too much with too little. Behaviourism says little about how the mi= nd works, and provides no useful account of conscious experience. Those familiar with experimental p= sychology will know that despite its popularity in the first half of the 20th Century, from the 1950’s onwards the theoretical poverty of this approach, combined with the availability of more powerful information processing approaches, led to its virtual abandonment in cognitive science. It remains true that= the conscious experiences of others cannot be directly accessed from an external observer’s third person perspective. Nevertheless, with the developme= nt of increasingly sophisticated combinations of first- and third-person metho= ds, for example in 21st Century cognitive neuroscience, Hoche’s attempt to dismiss consciousness from nature based on a behaviourist understanding of other minds sounds very much like a lone voice from the pa= st.
Hoche concludes his paper= with an attempt to reanalyse psychophysical causation. Unfortunately his descriptio= n of my own approach to this issue, involving dual-aspect, monist ontology, comb= ined with a complimentary first- and third-person perspective epistemology is to= o cursory to solicit a detailed commentary. Instead he focuses on his own noematic approach, which ironically follows the dual-aspect approach that I develop = in rough outline. For example, in Velmans, 1991a,b, 1993, 1996, 2002a,b I have argued that psychophysical causation presents a “causal paradox”= ;: if the mind/brain is viewed from a third-person perspective, consciousness seems to be epiphenomenal, while viewed from a first-person perspective consciousness appears to be central for much of what we do. The challenge i= s to understand the causal interactions between consciousness and brain in a way that saves both these appearanc= es.
In similar fashion Hoch= e writes that,
“…although = it may be rightly taken for granted that material occurrences out in the world can causally provoke neurophysiological occurrences in my central nervous syste= m as well as pieces of my overt behaviour (and vice versa), strictly speaking neither of them can cause, or be caused by, subjective conscious experiences of mine. Of course it would be preposterou= s to deny what appears to be clear-c= ut cases of psychophysical (or physiopsychical) causation; but we are confront= ed with the challenging task of concep= tually reinterpreting such cases so as to agree with the prerequisites of anthropological complementarity properly understood.” (p ).
While this uses differe= nt language it expresses a very similar view.= And, while Hoche does = not formulate a resolution of this paradox in, say, the detail offered in Velma= ns (2000, chapter 11) or Velmans (2002a), it moves in a similar direction—for example, in his conclusion that correlations between conscious experiences and brain states can only be established intersubjectively (p 27?).
That said, Hoche’s = noematic account strips away the ‘glue’ that holds my own account of psychological causation together—i.e. it abandons my suggestion that there really is a mind that rea= lly has a nature, in which real causal processes operate, whi= ch can be known in two complementary, first- and third-person ways. Hoche’s minimalism is consistent with the position that he adopts throughout his pa= per. Unwilling to posit any reality behind the appearances other than what can be abstracted from the conjunction of the appearances, he falls victim to the = same problem: he can describe the appearances but he can’t explain them—the restricted = tools that he permits himself simply cannot do the job.
In conclusion, let me s=
ay once
again how much I appreciate Hoche’s careful analysis of some aspects =
of
reflexive monism in the first part of his paper. I also respect Hoche’=
;s
attempt to argue for a more minimalist “purely noematic”,
‘semi-behaviourist’ position in the later part of his paper.
However, in my judgment, his minimalism comes at a cost: his explanations a=
re
more complex, explain less, and have many counterintuitive consequences.

[1] For = the purposes of this example we are concerned only with the phenomenology of vi= sual experiences, not with feelings about the cat, thoughts about the cat and so= on.
[2] While these views of the cat itself a= re numerically and perspectivally different, both S and E experience a cat out in the world, and in this resp= ect their experiences are similar.
[3] I suggest that phenomenal representations are “in part” construct= ed by the mind/brain, for the reason that I accept that the mind/brain is in t= urn embedded in a body, embedded in the world, so in a broader sense the phenom= enal representations are constructed by the entire, interacting system.
[4] We c= an of course extend the capacities= of our perceptual and cognitive systems, by training or with the aid of technology. However, extendin= g the range of our perceptual and cognitive systems does not free them of all constraints.
[5] This point is supplementary to the classical philosophical distinction between (uncertain) contingent truth and (certain) necessary truth. Scientific knowledge can only be g= ained by empirical investigation because it is contingent on how the world happen= s to be (when it could be otherwise). Necessary truths are certain because they = are true in any possible universe, so they do not require any empirical investigation.
[6] Illu= sory phenomena might not represent anything real (other than the workings of the mind itself), in which case one could think of them as mental constructions which do not represent what they seem to represent. But if they are representations of the world they must tell us something about what the world is “really” like, or they are not representations of the world (in this usage, a complete misrepresentation d= oes not count as a “representation”).
[7] I use the neutral term “thing” as convenient shorthand here, but leave open the question of whether a given object of knowledge is better thought = of as a thing, event, or process.
