The most incorporate tool—we will say an eye, or a tooth, or the closed fist when used to strike—has still something of the _non ego_ about it in so far as it is used; those organs, again, that are the most completely separate from the body, as the locomotive engine, must still from time to time kiss the soil of the human body, and be handled and thus crossed with man again if they would remain in working order. They cannot be cut adrift from the most living form of matter (I mean most living from our point of view), and remain absolutely without connection with it for any length of time, any more than a seal can live without coming up sometimes to breathe; and in so far as they become linked on to living beings they live. Everything is living which is in close communion with, and interpermeated by, that something which we call mind or thought. Giordano Bruno saw this long ago when he made an interlocutor in one of his dialogues say that a man’s hat and cloak are alive when he is wearing them. “Thy boots and spurs live,” he exclaims, “when thy feet carry them; thy hat lives when thy head is within it; and so the stable lives when it contains the horse or mule, or even yourself;” nor is it easy to see how this is to be refuted except at a cost which no one in his senses will offer.
It may be said that the life of clothes in wear and implements in use is no true life, inasmuch as it differs from flesh and blood life in too many and important respects; that we have made up our minds about not letting life outside the body too decisively to allow the question to be reopened; that if this be tolerated we shall have societies for the prevention of cruelty to chairs and tables, or cutting clothes amiss, or wearing them to tatters, or whatever other absurdity may occur to idle and unkind people; the whole discussion, therefore, should be ordered out of court at once.
I admit that this is much the most sensible position to take, but it can only be taken by those who turn the deafest of deaf ears to the teachings of science, and tolerate no going even for a moment below the surface of things. People who take this line must know how to put their foot down firmly in the matter of closing a discussion. Some one may perhaps innocently say that some parts of the body are more living and vital than others, and those who stick to common sense may allow this, but if they do they must close the discussion on the spot; if they listen to another syllable they are lost; if they let the innocent interlocutor say so much as that a piece of well-nourished healthy brain is more living than the end of a finger-nail that wants cutting, or than the calcareous parts of a bone, the solvent will have been applied which will soon make an end of common sense ways of looking at the matter. Once even admit the use of the participle “dying,” which involves degrees of death, and hence an entry of death in part into a living body, and common sense must either close the discussion at once, or ere long surrender at discretion.
