Jealousy is a painful passion; yet without some share of it, the agreeable affection of love has difficulty to subsist in its full force and violence.
David HumeWeakness, fear, melancholy, together with ignorance, are the true sources of superstition. Hope, pride, presumption, a warm indignation, together with ignorance, are the true sources of enthusiasm.
David HumeHow can we satisfy ourselves without going on in infinitum? And, after all, what satisfaction is there in that infinite progression? Let us remember the story of the Indian philosopher and his elephant. It was never more applicable than to the present subject. If the material world rests upon a similar ideal world, this ideal world must rest upon some other; and so on, without end. It were better, therefore, never to look beyond the present material world.
David Hume
