All theories of morality agree in considering that conduct whose total results, immediate and remote, are beneficial, is good conduct; while conduct whose total results, immediate and remote, are injurious, is bad conduct. The happiness or misery caused by it are the ultimate standards by which all men judge of behavior.
Herbert Spencer (1820-1903) English philosopher, naturalist
