This looks aweful familiar.
I link all of my Intro Students to A2K to expose them to Philosophical Discussion.
I also assign them journals where I ask them several questions to guide thier reading.
One of them is to describe Descartes version of truth (The cogito plus his methodology)
If this is one of my students - you may be in for a raukus time with this bunch.

Buckle up -
Everything I have seen thusfar on this thread is explaining better than I can...
Good luck.

p.s. If I am off base - simply ignore this message as an odd coincidence.
