it was required for my philosophy degree.
What's required is an ability to apply logic to basic principles (like hedonism and utilitarianism as I mentioned in another post) so as to be able to take application of those principles to real life situations to see their ramifications... similar to the food inspection example I used in my post.
You'll have to write essays; at least, you will if the course is any good. I would expect reading to stretch from Plato and Aristotle through various enlightenment folks like Descartes, Hume, and Kant, on up to modern and post-modern folks.
Should be interesting, if you decide to take it on.
