“There are four classes of idols which beset men’s minds. To these for distinction’s sake I have assigned names—calling the first class Idols of the Tribe; the second, Idols of the Cave; the third, Idols of the Market-Place; the fourth, Idols of the Theatre.”

Francis Bacon (1561–1626), British philosopher, essayist, political figure. Novum Organum, Aphorism 39 (1620).
