The familiar expression, 'to look into another's soul,' which by force of habit at first sight seems extremely intelligible, on closer observation appears so unintelligible that one is forced to ask whether it has any meaning at all. Try to bend, mentally, over another's soul: you will see nothing but a vast, empty, black abyss, and you will only be seized with giddiness for your pains. Thus, properly speaking, the expression 'to look into another's soul' is only an abortive metaphor. All that we can do is to argue from the outward data to the inward feelings. From tears we deduce pain, from pallor, fear, from a smile, joy. But is this to look into another's soul? It is only to give room to a series of purely logical processes in one's head. The other's soul remains as invisible as before; we only guess at it, perhaps rightly, perhaps mistakenly. Naturally this conclusion irritates us. What a miserable world it is where it is quite impossible to see the very thing that we desire above all to see. But irritation is almost the normal spiritual state of a man who thinks and seeks. Whenever it is particularly important to him to be sure of something, after a number of desperate attempts he is convinced that his curiosity cannot be satisfied. And now the mocking mind adds a new question to the old: Why look for another's soul when you have not seen your own? And is there a soul? Many have believed and still do believe that there is no soul at all, but only a science of it, called psychology. It is known that psychology says nothing of the soul, considering that its task is confined to the study of spiritual states--states, by the way, which have as yet hardly been studied at all.... What is the way out? One can answer irony with irony, or even with abuse. One can deny psychology the right to be called a science and call the materialists a pack of fools, as is often done. Incontestably, anger has its rights. But this has sense and meaning only while you are among people and are listened to. Nobody wants to be indignant alone with oneself, when one is not even reckoning upon making use of one's indignation for literary purposes: for even a writer is not always writing, and is more often preoccupied with transitory thoughts than with his forthcoming works. One prefers to approach the enchanted cave, though for the thousandth time, with every possible precaution. Perhaps it is only upon the approach of an outside soul that another's soul becomes invisible, and if she be caught unawares she will not have time to disappear. So that ponderous psychology, which like any other science always proclaims its plans and methods aloud before undertaking anything, is utterly unsuited to the capture of a thing so light and mobile as the human soul. But let us leave psychology with the honourable name of science; let us even respect the materialists, while we endeavour to track down the soul by other means. Perhaps in the depth of the dark
