Time Saving Truth from Falsehood and Envy (completed on the day before the artist’s suicide in Paris, 1737, by stabbing himself)
"There seems to be a constant decay of all our ideas; even of those which are struck deepest, and in minds the most retentive, so that if they be not sometimes renewed by repeated exercises of the senses, or reflection on those kinds of objects which at first occasioned them, the print wears out, and at last there remains nothing to be seen."
Locke—Human Understanding. Bk. II. Ch. 10.
"Times are bad. Children no longer obey their parents and everyone is writing a book."
Cicero, 43 BCE
