11 famous executives who majored in philosophy

Reid HoffmanKevin Moloney/Fortune Brainstorm TechLinkedIn cofounder Reid Hoffman was almost a philosophy professor.

Through one lens, the study of philosophy is the purest intellectual quest there is. Through another, it’s a punch line.

(Q: How many philosophers does it take to change a light-bulb?

A: Three: one to change the lightbulb, and to to debate whether they ought to, and if so, whether it follows that they can. This one is from The Philosopher’s Cocoon, but are more where that came from.)

But while it’s easy to dismiss philosophy as one of the “soft” humanities that is, as star venture capitalist Marc Andreessen once said, a sure path to “working in a shoe store,” it’s also short-sighted.

It’s true that most high-powered jobs won’t have you curled up in a cubical debating the finer points of Heidegger, but it’s also true that the skills you learn studying those ideas — how to think critically, write well, analyse complicated concepts, and sell ideas — can pay off in the business world. And as these 12 industry leaders prove, they can pay off big.

Until the summer of 2011, Bair served as the chairwoman of the Federal Deposit Insurance Corporation, having been appointed by George W. Bush in 2005.

'My original plan was to become an academic,' the entrepreneur and venture capitalist told Wired, and Hoffman was on track to make it happen: after graduating from Stanford with a degree in Symbolic Systems, he won a Marshall Scholarship to study philosophy at Oxford. 'What I most wanted to do was strengthen public intellectual culture -- I'd write books and essays to help us figure out who we wanted to be.'

Frustrated by the pace and impact of academic work -- 'it didn't have enough scale,' he told Wired -- he changed directions and became a software entrepreneur. After working with his Stanford friends (including Peter Theil) at PayPal, he launched LinkedIn in 2003.
