Still, though the two forms of goodness are thus regularly united, we may fix our attention on the one or the other. According as we do so, we speak of an object as intrinsically or extrinsically good. For that matter, one of the two may sometimes seem to be present in a preponderating degree, and to determine by its presence the character of the object. In judging ordinary physical things, I believe we usually test them by their serviceability to us--by their extrinsic goodness, that is--rather than bother our heads with asking what is their inner structure, and how full of organization they may be. Whereas, when we come to estimate human beings, we ordinarily regard it as a kind of indignity to assess primarily their extrinsic goodness, _i. e_., to ask chiefly how serviceable they may be and to ignore their inner worth. To sum up a man in terms of his labor value is the moral error of the slaveholder. If, however, we seek the highest point to which either kind of excellence may be carried, it will be found where each most fully assists the other. But this is not easy to imagine. When I set a glass of water on the table, the table is undoubtedly slightly shaken by the strain. If I put a large book upon it, the strain of the table becomes apparent. Putting a hundred pound weight upon it is an experiment that is perilous. For the extrinsic goodness of the table is at war with the intrinsic; that is, the employment of the table wears it out. In doing its work and fitting into the large relationships for which tables exist, its inner organization becomes disjointed. In time it will go to pieces. We can, however, imagine a magic table, which might be consolidated by all it does. At first it was a little weak, but by upholding the glass of water it grew stronger. As I laid the book on it, its joints acquired a tenacity which they lacked before; and only after receiving the hundred pound weight did it acquire the full strength of which it was capable. That would indeed be a marvelous table, where use and inner construction continually helped each other. Something like it we may hereafter find possible in certain regions of personal goodness, but no such perpetual motion is possible to things. For them employment is costly. VII
