The fact is that we make our conceptions in accordance with the things as we have seen them, and so completely persuade ourselves of the truth of one definite, partial definition, that sometimes we wonder at a phenomenon without judging that it might have been expected to be otherwise. When I first became a student at Strassbourg, I wondered, subconsciously, when I heard the ragged gamins talk French fluently. I knew, indeed, that it was their mother-tongue, but I was so accustomed to viewing all French as a sign of higher education that this knowledge in the gamins made me marvel. When I was a child I once had to bid my grandfather adieu very early, while he was still in bed. I still recall the vivid astonishment of my perception that grandfather awoke without his habitual spectacles upon his nose. I must have known that spectacles are as superfluous as uncomfortable and dangerous when one is sleeping, and I should not even with most cursory thinking have supposed that he would have worn his spectacles during the night. But as I was accustomed always to see my grandfather with spectacles, when he did not have them I wondered at it. Such instances are of especial importance when the judge is himself making observations, i.e., examining the premises of the crime, studying corpora delicti, etc., because we often suppose ourselves to see extraordinary and illegal things simply because we have been habituated to seeing things otherwise. We even construct and name according to this habit. Taine narrates the instructive story of a little girl who wore a medal around her throat, of which she was told, “C’est le bon Dieu.” When the child once saw her uncle with a lorgnon around his neck she said, “C’est le bon Dieu de mon oncle.” And since I heard the story, I have repeatedly had the opportunity to think, “C’est aussi le bon Dieu de cet homme.” A single word which indicates how a man denotes a thing defines for us his nature, his character, and his circumstances.
