All religions are equally sublime to the ignorant, useful to the politician, and ridiculous to the philosopher. - Titus Lucretius Carus

это вовсе не Лукреций господибожемой

Actually said by Edward Gibbonː "The various modes of worship, which prevailed in the Roman world, were all considered by the people, as equally true; by the philosopher, as equally false; and by the magistrate, as equally useful." (The History of the Decline and Fall of the Roman Empire, 1776, Vol. I, Ch. II).

так что не 2000 лет, а всего 250. но это уже сказано во времена Вольтера и Дидро, подобные взгляды тогда были довольно популярны.
