I don't think I ever relinquish a person I have known, and surely not my fictional characters. I see them, I hear them, with a clarity that I would call hallucinatory if hallucination didn't mean something else ... A character whom we create can never die, any more than a friend can die ... Through [my characters] I've lived many parallel lives.

I knew that good like bad becomes a routine, that the temporary tends to endure, that what is external permeates to the inside, and that the mask, given time, comes to be the face itself.

[On travel:] Who would be so besotted as to die without having made at least the round of this, his prison?

Everything turns out to be valuable that one does for one’s self without thought of profit.

One nourishes one's created characters with one's own substance: it's rather like the process of gestation. To give the character life, or to give him back life, it is of course necessary to fortify him by contributing something of one's own humanity, but it doesn't follow from that that the character is I, the writer, or that I am the character. The two entities remain distinct.

The landscape of my days appears to be composed, like mountainous regions, of varied materials heaped up pell-mell. There I see my nature, itself composite, made up of equal parts of instinct and training. Here and there protrude the granite peaks of the inevitable, but all about is rubble from the landslips of chance.

The technique of a great seducer requires a facility and an indifference in passing from one object of affection to another which I could never have; however that may be, my loves have left me more often than I have left them, for I have never been able to understand how one could have enough of any beloved. The desire to count up exactly the riches which each new love brings us, and to see it change, and perhaps watch it grow old, accords ill with multiplicity of conquests.
