Travel is a caprice in childhood, a passion in youth, a necessity in manhood, and an elegy in old age.

Man works for an object. Remove that object and you reduce him into inaction.

To live is to be among men, and to be among men is to struggle, a struggle not only with them but with oneself; with their passions, but also with one's own.

On this battlefield man has no better weapon than his intelligence, no other force but his heart.

To doubt God is to doubt one's own conscience, and in consequence it would be to doubt everything.

What is death to me? I have sown the seeds others will reap.

Tomorrow at 7, I shall be shot; but I am innocent of the crime of rebellion. I am going to die with a tranquil conscience.
