“See that the mind is honest, first; the rest may follow or not as God wills. [That] the fundamental treason to the mind ... is the one fundamental treason which the scholar's mind must not allow is the bond uniting all the Oxford people in the last resort.”

“This new approach, it seemed, was not to be made so publicly, not to be exposed to the expedient treason of little devious minds far removed from the battlefields on which honest men met, and contended, and killed one another without malice.”

“It is all too easy to mistake passion that can change its mind for fundamentalism, which never will.”

“Fundamentalism is dictatorship of the mind”

“There is but one truly serious philosophical problem and that is suicide. Judging whether life is or is not worth living amounts to answering the fundamental question of philosophy. All the rest — whether or not the world has three dimensions, whether the mind has nine or twelve categories — comes afterwards. These are games; one must first answer.”

“It is treason to sacrifice love of truth, intellectual honesty, loyalty to the laws and methods of the mind, to any other interests, including those of one's country.”
