I could say much about politics, our only entertainment here, but you would not care a fig about that.

The human character, we believe, requires in general constant and immediate control to prevent its being biased from right by the seductions of self-love.

When I hear another express an opinion which is not mine, I say to myself, he has a right to his opinion, as I to mine. Why should I question it? His error does me no injury, and shall I become a Don Quixote, to bring all men by force of argument to one opinion? ...Be a listener only, keep within yourself, and endeavor to establish with yourself the habit of silence, especially in politics.

I have never conceived that having been in public life required me to belie my sentiments, or to conceal them. Opinion and the just maintenance of it shall never be a crime in my view, nor bring injury on the individual. I never will by any word or act, bow to the shrine of intolerance. I never had an opinion in politics or religion which I was afraid to own; a reserve on these subjects might have procured me more esteem from some people, but less from myself.

Let the eye of vigilance never be closed.

Reading, reflection and time have convinced me that the interests of society require the observation of those moral precepts only in which all religions agree (for all forbid us to steal, murder, plunder, or bear false witness), and that we should not intermeddle with the particular dogmas in which all religions differ, and which are totally unconnected with morality.

Preachers dread the advance of science as witches do the approach of daylight.
