Rene Descartes Deceived Quotations

The senses deceive from time to time, and it is prudent never to trust wholly those who have deceived us even once.

Whatever I have up till now accepted as most true and assured I have gotten either from the senses or through the senses. But from time to time I have found that the senses deceive, and it is prudent never to trust completely those who have deceived us even once.
