“To have no time for philosophy is to be a true philosopher.”

“To make light of philosophy is to be a true philosopher.”

“Socrates: So even our walks are dangerous here. But you seem to have avoided the most dangerous thing of all.Bertha: What's that?Socrates: Philosophy. Bertha: Oh, we have philosophers here. Socrates: Where are they?Bertha: In the philosophy department.Socrates: Philosophy is not department. Bertha: Well, we have philosophers.Socrates: Are they dangerous?Bertha: Of course not.Socrates: Then they are not true philosophers.”

“Noone has yet succeeded in inventing a philosophy at once credible and self-consistent. Locke aimed at credibility, and achieved it at the expense of consistency. Most of the great philosophers have done the opposite. A philosophy which is not self-consistent cannot be wholly true, but a philosophy which is self-consistent can very well be wholly false. The most fruitful philosophies have contained glaring inconsistencies, but for that very reason have been partially true. There is no reason to suppose that a self-consistent system contains more truth than one which, like Locke’s, is more or less wrong.”

“To ridicule philosophy is really to philosophize.”

“There are nowadays professors of philosophy, but not philosophers.”
