David Hume,
Treatise of Human Nature/Book 2…
(1739)
“ The very essence of riches consists in the power of procuring the pleasures and conveniences of life. The very essence of this power consists in the probability of its exercise, and in its causing us to anticipate, by a true or false reasoning, the real existence of the pleasure. This anticipation of pleasure is, in itself, a very considerable pleasure; and as its cause is some possession or property, which we enjoy, and which is thereby related to us, we here clearly see all the parts of the foregoing system most exactly and distinctly drawn out before us. ”
