Rationally Speaking

Rationally Speaking
by Massimo PigliucciAs I mentioned before, this semester I’m teaching a graduate level seminar on David Hume, and having lots of fun with it. During a recent discussion of sections 4 and 5 of the Enquiry Concerning Human Understanding (“Sceptical doubts concerning the operations of the understanding” and “Sceptic al solutions of these doubts”) the concept of metaphysical necessity came up.As is well known, Hume wasn’t very keen on metaphysics in general. One of the most famous quotes by him (in section 12 of the very same Enquiry) says: “If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any abstract reasoning concerning quantity or number?

Now society is coming to understand that the broad spectrum of autism — as it’s currently defined, which will change next year with the publication of the DSM-5 – isn’t rare after all.

Philosophy: Guide to Happiness We tend to accept that people in authority must be right. It's this assumption that Socrates wanted us to challenge by urging us to think logically about the nonsense they often come out with, rather than being struck dumb by their aura of importance and air of suave certainty. This six part series on philosophy is presented by popular British philosopher Alain de Botton, featuring six thinkers who have influenced history, and their ideas about the pursuit of the happy life. Socrates on Self-Confidence (Part 1) - Why do so many people go along with the crowd and fail to stand up for what they truly believe? Partly because they are too easily swayed by other people's opinions and partly because they don't know when to have confidence in their own.

The Rogues Gallery Sam, an SGU listener, brought this to our attention the other day (thank you, Sam.) A new podcast has hit the iTunes shelves. It is called Scripture on Creation.
