René Descartes,
Six metaphysical meditations
(1680)
“ Corporeal Things (whose Images are formed in my thought, and which by my senses, I perceive) are much more distinctly known, then that confused Notion of My Self which imagination cannot afford me. And yet ’tis strange that things doubtful, unknown, distinct from Me, should be apprehended more clearly by Me, then a Thing that is True, then a thing that is known, or then I my self; But the Reason is, that my Mind loves to wander, and suffers not it self to be bounded within the strict limits of Truth. ”
