Immanuel Kant, 1724-1804, a German philosopher, reasoned that "[A]n orang-utan or a chimpanzee may develop the organs which serve for walking, grasping objects, and speaking – in short, that he may evolve the structure of man, with an organ for the use of reason . . . (Kant, 1798 in Anthropology)"
Now, I would really like to find a copy of Anthropology so as to find the reasoning that led to this conclusion.
