Love is a striking example of how little reality means to us. - Marcel Proust

when a creature is so badly constituted (perhaps in nature that being is man) that he cannot love unless he suffers and that he must suffer to learn truth, the life of such a being becomes in the end very exhausting. The happy years are those that are wasted; we must wait for suffering to drive us to work.

Now are the woods all black,
But still the sky is blue.

The so-called sensitivity of neurotics develops along with their egotism; they cannot bear for other people to flaunt the sufferings with which they are increasingly preoccupied themselves.
