“The care of human life and happiness, and not their destruction, is the first and only legitimate object of good government.”

1820s, Letter to A. Coray (1823)
Source: Letters of Thomas Jefferson
Context: The equal rights of man, and the happiness of every individual, are now acknowledged to be the only legitimate objects of government. Modern times have the signal advantage, too, of having discovered the only device by which these rights can be secured, to wit: government by the people, acting not in person, but by representatives chosen by themselves, that is to say; by every man of ripe years and sane mind, who either contributes by his purse or person to the support of his country.

1770s, Declaration of Independence (1776)
Context: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness.—That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Inaugural address (March 4, 1841)

Independence Day speech (1828)
Context: Americans no longer argue on the propriety of making all men soldiers, in order that their nation may be an object of terror to the rest of the world. They understand that the happiness of a people is the only rational object of a government, and the only object for which a people, free to choose, can have a government at all. They have, farther, almost excluded war as a profession, and reduced it from a system of robbery to one of simple defence. In so doing, they ought also to have laid aside all show of military parade, and all ideas of military glory. If they have not done so, it is that their reform in this matter is yet imperfect, and their ideas respecting it are confused.

Section 147
The Passionate State Of Mind, and Other Aphorisms (1955)
Context: The only index by which to judge a government or a way of life is by the quality of the people it acts upon. No matter how noble the objectives of a government, if it blurs decency and kindness, cheapens human life, and breeds ill will and suspicion — it is an evil government.

infinity plus interview (2001)
Context: The battle between good and evil is a legitimate theme for a Fantasy (or for any work of fiction, for that matter), but in real life that battle is fought chiefly in the individual human heart. Too many contemporary Fantasies take the easy way out by externalizing the struggle, so the heroic protagonists need only smite the evil minions of the dark power to win the day. And you can tell the evil minions, because they're inevitably ugly and they all wear black.
I wanted to stand much of that on its head.
In real life, the hardest aspect of the battle between good and evil is determining which is which.
