A Quote by David Starr Jordan on action, chance, charity, effort, evil, good, happiness, laws, life, energy, losing, misery, power, success, and wealth

The physiological law of Transfer of Energy is the basis of human success and happiness. There is no action without expenditure of energy, and if energy be not expended the power to generate it is lost. This law shows itself in a thousand ways in the life of man. The arm which is not used becomes palsied. The wealth which comes by chance weakens and destroys. The good which is unused turns to evil. The charity which asks no effort cannot relieve the misery she creates.
