Yes, say certain philosophers, our senses may be finite and untrustworthy, but our understanding, and still further our reason, they are unlimited, and recognise nothing which is beyond them. Well, what does this most wise understanding do for us? Has not Hobbes long since taught us that it adds and subtracts, and voilà tout? It receives the impressions of the senses, combines them, feels them, comprehends and designates or names them after any characteristic, and when man has found words, then the adding and subtracting begin, but unfortunately also the jumbling and chattering, till we finally establish that philosophy and religion, which have aroused in so great degree your anger, and even your blood thirstiness. In spite of all it remains true that we can no more get beyond the horizon of our senses than we can jump out of our skins. You know that old saying of Locke's, although it is much older than Locke, that there is nothing in our intellect which was not first in our senses. And therefore, however much we may extend our knowledge by adding and subtracting, everywhere we feel in the end our horizon, our limitations, our ignorance, for with the limitations of our senses it cannot be otherwise. Invariably we receive the old answer, You are like the mind which you conceive, not me.
