« Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites; in proportion as their love for justice is above their rapacity; in proportion as their soundness and sobriety of understanding is above their vanity and presumption; in the proportion as they are more disposed to listen to the counsels of wise and good, in preference to the flattery of knaves. Society cannot exist unless a controlling power upon will and appetite be placed somewhere, and less of it there is within, the more there must be without. It is ordained in the eternal constitution of things that men of intemperate minds cannot be free. Their passions forged their fetters. » (Edmund Burke)
