T.S. Arthur

“Every physical form that we see in nature is the outbirth of some spiritual and invisible cause; and the peculiarity of its form and quality depends solely upon the peculiarities of its cause... Keeping in this view, it may readily be seen, that what makes a man a man, and a woman a woman, is not the body, but the mind; and, as the body is formed from, by, or through the mind as cause, the mind of a man must be different from the mind of a woman...”
