Moral for psychologists. — Not to go in for backstairs psychology. Never to observe in order to observe! That gives a false perspective, leads to squinting and something forced and exaggerated. Experience as the wish to experience does not succeed. One must not eye oneself while having an experience; else the eye becomes “an evil eye.” A born psychologist guards instinctively against seeing in order to see; the same is true of the born painter. He never works “from nature”; he leaves it to his instinct, to his camera obscura, to sift through and express the “case,” “nature,” that which is “experienced.” He is conscious only of what is general, of the conclusion, the result: he does not know arbitrary abstractions from an individual case. What happens when one proceeds differently? For example, if, in the manner of the Parisian novelists, one goes in for backstairs psychology and deals in gossip, wholesale and retail? Then one lies in wait for reality, as it were, and every evening one brings home a handful of curiosities. But note what finally comes of all this: a heap of splotches, a mosaic at best, but in any case something added together, something restless, a mess of screaming colors. The worst in this respect is accomplished by the Goncourts; they do not put three sentences together without really hurting the eye, the psychologist’s eye. Nature, estimated artistically, is no model. It exaggerates, it distorts, it leaves gaps. Nature is chance. To study “from nature” seems to me to be a bad sign: it betrays submission, weakness, fatalism; this lying in the dust before petit faits [little facts] is unworthy of a whole artist. To see what is — that is the mark of another kind of spirit, the anti-artistic, the factual. One must know who one is.
