“If refined sense and exalted sense be not so useful as common sense, their rarity, their novelty, and the nobleness of their objects make some compensation, render them the admiration of mankind: As gold, though less serviceable than iron, acquires, from its scarcity, a value, which is much superior.” (David Hume, An Enquiry Concerning the Principles of Morals (Hackett 1983) p. 56.)
