Thus we never see the true state of our condition till it is illustrated to us by its contraries, nor know how to value what we enjoy, but by the want of it.
Daniel DefoeI smil'd to my self at the sight of this money, O drug! said I aloud, what art thou good for? Thou art not worth to me, no not the taking off of the ground, one of those knives is worth all this heap, I have no manner of use for thee, e'en remain where thou art, and go to the bottom as a creature whose life is not worth saving. However, upon second thoughts, I took it away.
Daniel Defoe
