There comes no adventure but wears to our soul the shape of our everyday thoughts.

I have done what I could do in life, and if I could not do better, I did not deserve it. In vain I have tried to step beyond what bound me.

At every crossway on the path that leads to the future, each progressive spirit is opposed by a thousand men appointed to guard the past. Let us have no fear that the fair towers of former days be sufficiently defended. The least that the most timid among us can do is not to add to the immense dead weight that nature drags along.

All our knowledge merely helps us to die a more painful death than animals that know nothing.

An obstacle is not a discouragement. It may become one, but only with our own consent. So long as we refuse to be discouraged, we cannot be discouraged.

We are never the same with others as when we are alone. We are different, even when we are in the dark with them.

To be happy is only to have freed one's soul from the unrest of unhappiness.
