Train yourself never to put off the word or action for the expression of gratitude.

But merely accepting authoritarian truth, even if that truth has some virtue, does not bring skepticism to an end. To blindly accept a truth one has never reflected upon retards the advance of reason. Our world rots in deceit. . . . Just as a tree bears the same fruit year after year and at the same time fruit that is new each year, so must all permanently valuable ideas be continually created anew in thought. But our age pretends to make a sterile tree bear fruit by tying fruits of truth onto its branches.

If you study life deeply, its profundity will seize you suddenly with dizziness.

Let us rejoice in the truth, wherever we find its lamp burning.

Faith which refuses to face indisputable facts is but little faith. Truth is always gain, however hard it is to accommodate ourselves to it. To linger in any kind of untruth proves to be a departure from the straight way of faith.

Ethical existence [is] the highest manifestation of spirituality.
