All knowledge is of itself of some value. There is nothing so minute or inconsiderable, that I would not rather know it than not. In the same manner, all power, of whatever sort, is of itself desirable. A man would not submit to learn to hem a ruffle, of his wife, or his wife's maid; but if a mere wish could attain it, he would rather wish to be able to hem a ruffle.

— Samuel Johnson
