What is so beneficial to the people as liberty, which we see not only to be greedily sought after by men, but also by beasts, and to be prepared in all things.
In all great arts, as in trees, it is the height that charms us; we care nothing for the roots or trunks, yet it could not be without the aid of these.
Though liberty is established by law, we must be vigilant, for liberty to enslave us is always present under that very liberty. Our Constitution speaks of the "general welfare of the people." Under that phrase all sorts of excesses can be employed by lusting tyrants to make us bondsmen.
There exists a law, not written down anywhere but inborn in our hearts; a law which comes to us not by training or custom or reading but by derivation and absorption and adoption from nature itself; a law which has come to us not from theory but from practice, not by instruction but by natural intuition. I refer to the law which lays it down that, if our lives are endangered by plots or violence or armed robbers or enemies, any and every method of protecting ourselves is morally right.
Vicious habits are so great a stain to human nature, and so odious in themselves, that every person actuated by right reason would avoid them, though he were sure they would be always concealed both from God and man, and had no future punishment entailed upon them.
