The life of the law has not been logic; it has been experience.

The advice of the elders to young men is very apt to be as unreal as a list of the hundred best books.

Our test of truth is a reference to either a present or imagined future majority in favour of our view.

But when men have realized that time has upset many fighting faiths, they may come to believe...that the best test of truth is the power of the thought to get itself accepted in the competition of the market... That at any rate is the theory of our constitution.

Fame is the scentless sunflower, with gaudy crown of gold; But friendship is the rose, with sweets in every fold.

Systems die; instincts remain.
