I remain convinced that obstinate addiction to ordinary language in our private thoughts is one of the main obstacles to progress in philosophy.

The man who can centre his thoughts and hopes upon something transcending self can find a certain peace in the ordinary troubles of life, which is impossible to the pure egoist.

The wise man thinks about his troubles only when there is some purpose in doing so; at other times he thinks about other things

Philosophy is an unusually ingenious attempt to think fallaciously.

Freedom in general may be defined as the absence of obstacles to the realization of desires.

I would never die for my beliefs because I might be wrong.
