“To know what actions are virtuous, and what vicious — in other words, to know what actions tend, on the whole, to happiness, and what to unhappiness — in the case of each and every man, in each and all the conditions in which they may severally be placed, is the profoundest and most complex study to which the greatest human mind ever has been, or ever can be, directed. It is, nevertheless, the constant study to which each and every man — the humblest in intellect as well as the greatest — is necessarily driven by the desires and necessities of his own existence. It is also the study in which each and every person, from his cradle to his grave, must necessarily form his own conclusions; because no one else knows or feels, or can know or feel, as he knows and feels, the desires and necessities, the hopes, and fears, and impulses of his own nature, or the pressure of his own circumstances.”
- Lysander Spooner in Vices are Not Crimes
