XXXVIII. TO GUSTAVE FLAUBERT, at Paris December, 1866

“Not put one’s heart into what one writes?” I don’t understand at all, oh! not at all! As for me, I think that one can not put anything else into it. Can one separate one’s mind from one’s heart? Is it something different? Can sensation itself limit itself? Can existence divide itself? In short, not to give oneself entirely to one’s work, seems to me as impossible as to weep with something else than one’s eyes, and to think with something else than one’s brain.

What was it you meant? You must tell me when you have the time.
