        abstract = {The quantum logical `or' is analyzed from a physical
perspective. We show that it is the existence of EPR-like correlation states
for the quantum mechanical entity under consideration that make it
nonequivalent to the classical situation. Specifically, the presence of
potentiality in these correlation states gives rise to the quantum
deviation from the classical logical
`or'. We show how this arises not only in the microworld, but also in
macroscopic situations where EPR-like correlation states are
present. We investigate how application of this analysis to concepts could
alleviate some well known
problems in cognitive science.
