61 - Nobody’s Perfect: the Stoics on Knowledge

The Stoics think there could be a perfect sage, so wise that he is never wrong. Is this a big mistake? Peter investigates their epistemology to find out.

The Sorites Paradox and a 5 year old

Peter,

I was listening to your podcast on the Stoics and Epistimology on the way home from work one day, and when I got home, I told my 9 year old daughter and 5 year old son the Sorities paradox. As I went through it, my daughter said that adding the 18th grain would make a heap, so I asked, of course, how can adding just one grain make a heap, and my son Ollie said, "no dad, you're not adding the one grain to the pile, you're adding the whole pile to the one grain; that's why it's now a heap". I may be as impartial as I am classically educated, but that's the best solution I've heard. If nothing else, it shows an amazing grasp of the commutative property of addition, and is a lot more ballsy than Chrysippus's solution!

You may not feel the same, but I can't wait for your summer break to end!

Thanks again for your podcasts.

Out of the mouths of babes

Thanks, that's a great story! Maybe you have a future philosopher in the making there. I agree, it's admirable that unlike certain Stoics we could name, Ollie was at least ready to take a stand.

The next episode goes up Sunday!
