@argome321,
There was no admission intended on my part of what we
both perceived.
Your use of the emotive word "rancid" implied a value judgement which
I might not have made given my internal state.
The point is that there may be no such thing as "pure sense data". Traditional empiricism (based on naive realism) tends to assume that there is. But following Kant's distinction between
noumena (things in themselves which we cannot access) and
phenomena (things in the mind) philosophers (phenomenologists and existentialists) have tended to hold
noumena as "hypothetical" at best.
