No earnest thinker is a plagiarist pure and simple. He will never borrow from others that which he has not already, more or less, thought out for himself.
Charles KingsleyIf I am ever obscure in my expressions, do not fancy that therefore I am deep. If I were really deep, all the world would understand, though they might not appreciate. The perfectly popular style is the perfectly scientific one. To me an obscurity is a reason for suspecting a fallacy.
