Certainly many of our most satisfying avocations today consist of making something by hand which machines can usually make more quickly and cheaply, and sometimes better. Nevertheless I must in fairness admit that in a different age the mere fashioning of a machine might have been an excellent hobby… Today the invention of a new machine, however noteworthy to industry, would, as a hobby, be trite stuff. Perhaps we have here the real inwardness of our own question: A hobby is a defiance of the contemporary.
It is an assertion of those permanent values which the momentary eddies of social evolution have contravened or overlooked. If this is true, then we may also say that every hobbyist is inherently a radical, and that his tribe is inherently a minority.
