Epictetus’ Epigraph to Tristram Shandy
Ταρασσει τοὐϚ Ἀνϑρώπους οὐ τὰ Πράγματα, αλλα τὰ περι τῶν Πραγμάτων, Δογματα.
It is not events [pragmata] themselves that trouble people, but their judgements [dogmata] about those circumstances.
Epictetus, Handbook 5
Pretty funny in context. The other half of the joke is that Laurence Sterne uses Locke’s association of ideas to explain how his mother came to associate the sound of her husband’s clock-winding with sex, providing the motor for Tristram’s life and the whole book.
