A Quote by Gottfried Wilhelm von Leibniz on deception, dreams, life, reason, and world
Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.
