"Whatever you do, you need courage. Whatever course you decide upon, there is always someone to tell you that you are wrong. There are always difficulties arising that tempt you to believe your critics are right. To map out a course of action and follow it to an end requires some of the same courage that a soldier needs. Peace has its victories, but it takes brave men and women to win them."
"Philosophically considered, the universe is composed of Nature and the Soul. Strictly speaking, therefore, all that is separate from us, all which Philosophy distinguishes as the 'Not Me,' that is, both nature and art, all other men and my own body, must be ranked under this name, 'Nature.'"
"Do not go where the path may lead, go instead where there is no path and leave a trail."
"Life is a series of surprises and would not be worth taking or keeping if it were not."
"He in whom the love of repose predominates will accept the first creed, the first philosophy, the first political party he meets — most likely his father's. He gets rest, commodity, and reputation; but he shuts the door of truth."
"What can we see, read, acquire, but ourselves. Take the book, my friend, and read your eyes out, you will never find there what I find."
