Marcus Tullius Cicero,
The Academic Questions, Treatise De Finibus…
“ For it is reason which has brought men the beginning of inquiry, which has perfected virtue, after reason herself had been confirmed by inquiry. But inquiry is the desire of knowledge; and the end of inquiry is discovery. But no one can discover what is false; nor can those things which continue uncertain be discovered. But when those things which have, as it were, been under a veil, are laid open, then they are said to be discovered; and so reason contains the beginning of inquiry, and the end of perceiving and comprehending. ”
