If a philosophic theory is once ruled out of court, no one can tell when it will appear again.

Again, both literature and philosophy work by appealing to certain reigning idols.

A creative element is surely present in all great systems, and it does not seem possible that all sympathy or fundamental attitudes of will can be entirely eliminated from any human philosophy.

Conservatism clings to what has been established, fearing that, once we begin to question the beliefs that we have inherited, all the values of life will be destroyed.

The picture which the philosopher draws of the world is surely not one in which every stroke is necessitated by pure logic.

Liberalism is an attitude rather than a set of dogmas - an attitude that insists upon questioning all plausible and self-evident propositions, seeking not to reject them but to find out what evidence there is to support them rather than their possible alternatives.

The method of exposition which philosophers have adopted leads many to suppose that they are simply inquiries, that they have no interest in the conclusions at which they arrive, and that their primary concern is to follow their premises to their logical conclusions.
