Aside: I find this subject fascinating, but sometimes I too wonder if we are chasing rabbits down holes where we have no business going.
But then I look back at Epicurus saying explicitly in the letter to Pythocles that these exact subjects should be included in basic studies so as to escape from superstition, so I think we're doing the right thing.
[116] ... All these things, Pythocles, you must bear in mind; for thus you will escape in most things from superstition and will be enabled to understand what is akin to them. And most of all give yourself up to the study of the beginnings and of infinity and of the things akin to them, and also of the criteria of truth and of the feelings, and of the purpose for which we reason out these things. For these points when they are thoroughly studied will most easily enable you to understand the causes of the details. But those who have not thoroughly taken these things to heart could not rightly study them in themselves, nor have they made their own the reason for observing them.
