Philosophy – discussion question – 200 words
Before we get any further into Descartes, tell me how you figure out what’s true.
How do you know anything?
And how can you make any kind of distinction between what you
know
is true and what you merely
believe
to be true? How much of your “knowledge” might turn out to just be mistaken beliefs?
Likewise, let’s talk about this issue of equal good sense. Do all people have it? Is it worth trying to convince other people when you think they’ve made a mistake? Can we compare notes and help each other figure anything out?
