...I believe there exists, & I feel within me, an instinct for the truth, or knowledge or discovery, of something of the same nature as the instinct of virtue, & that our having such an instinct is reason enough for scientific researches without any practical results ever ensuing from them.
Charles Darwin, Frederick Burkhardt, Sydney Smith (1985). “The Correspondence of Charles Darwin: 1847-1850”, p.128, Cambridge University Press
