Philosophical coherence is something that is illustrated over and over
again in any good first year Introduction to Philosophy course in any good
I assume that any FOM reader has had such a freshman course or at least
operates at at least that level when thinking philosophically.
I hesitate to get involved in any in depth discussion of philosophical
coherence because of my belief that anyone who isn't familiar with this
notion enough to see the special status of the usual formal systems of
f.o.m. is never going to get anything out of such a discussion. This would
be like screaming at a color blind person about all the rich colors they
are not paying attention to.
Chow obviously took some time to explain philosophical coherence in the
context at hand - and rather well.
I would be VERY INTERESTED to get an idea of whether any appreciable number
of FOM readers understood and related to Chow's post - that didn't already
feel comfortable with philosophical coherence in this context before
One reason I have been sceptical of even trying to do what Chow has done is
No one has challenged me on here to show how to present the usual f.o.m.
with philosophical coherence. And no one has tried to present categorical
foundations in a philosophically coherent way on here.
This suggests hardened positions that are not possible to budge. I'd be
curious if Chow is able to move this needle.
