Whatever debases the intelligence degrades the entire human being.

Affliction hardens and discourages us because, like a red hot iron, it stamps the soul to its very depths with the scorn, the disgust, and even the self-hatred and sense of guilt that crime logically should produce but actually does not.

When we hit a nail with a hammer, the whole of the shock received by the large head of the nail passes into the point without any of it being lost, although it is only a point. If the hammer and the head of the nail were infinitely big it would be just the same. The point of the nail would transmit this infinite shock at the point to which it was applied. Extreme affliction, which means physical pain, distress of soul and social degradation, all at the same time, constitutes the nail. The point is applied at the very center of the soul, whose head is all necessity, spreading throughout space and time.

One could count on one's fingers the number of scientists throughout the world with a general idea of the history and development of their particular science: there is none who is really competent as regards sciences other than his own. As science forms an indivisible whole, one may say that there are no longer, strictly speaking, scientists, but only drudges doing scientific work.

Do not allow yourself to be imprisoned by any affection. Keep your solitude. The day, if it ever comes, when you are given true affection, there will be no opposition between interior solitude and friendship, quite the reverse. It is even by this infallible sigh that you will recognize it.

When war is waged, it is for the purpose of safeguarding or increasing one's capacity to make war. International politics are wholly involved in this vicious cycle. What is called national prestige consists in behaving always in such a way as to demoralize other nations by giving them the impression that, if it comes to war, one would certainly defeat them. What is called national security is an imaginary state of affairs in which one would retain the capacity to make war while depriving all other countries of it.

There are only two things that pierce the human heart. One is beauty. The other is affliction.
