Descartes Meditations I par. 10:
“In whatever way it be supposed I reach the state in which I exist, whether by fate, or chance or by an endless series of antecedents and consequents, or by any other means [natural selection?] it is clear… that the probability of my being so imperfect as to be the constant victim of deception, will be increased exactly in proportion as the power possessed by the cause, to which they assign my origin, is lessened.”
This article shows why Descartes was right to worry that, if humans just came about naturally, by evolution, there is more probability that everything we think we know about the world is wrong.
