"I mean the whole economy just comes to a grinding halt. Competence in markets and in institutions, it's a lot like oxygen. When you have it, you don't even think about it. Indispensable. You can go years without thinking about it. When it's gone for five minutes, it's the only thing you think about. And the oxygen has been sucked out of the credit markets."

In the case of all other sciences, arts, skills, and crafts, everyone is convinced that a complex and laborious programme of learning and practice is necessary for competence. Yet when it comes to philosophy, there seems to be a currently prevailing prejudice to the effect that, although not everyone who has eyes and fingers, and is given leather and last, is at once in a position to make shoes, everyone nevertheless immediately understands how to philosophize.

— Georg Wilhelm Friedrich Hegel
