“Some men […] choose to seek greatness, while others are forced to it. It is always better to choose than to be forced.
A man who is forced is never completely his own master. He must dance on the strings of those who forced him.”

Religious Belief and Public Morality (1984)
Context: I protect my right to be a Catholic by preserving your right to believe as a Jew, a Protestant, or non-believer, or as anything else you choose.
We know that the price of seeking to force our beliefs on others is that they might some day force theirs on us.
This freedom is the fundamental strength of our unique experiment in government. In the complex interplay of forces and considerations that go into the making of our laws and policies, its preservation must be a pervasive and dominant concern.

1900s, Getting Married (1908)
Context: Religion is a great force — the only real motive force in the world; but what you fellows don't understand is that you must get at a man through his own religion and not through yours. Instead of facing that fact, you persist in trying to convert all men to your own little sect, so that you can use it against them afterwards. You are all missionaries and proselytizers trying to uproot the native religion from your neighbor's flowerbeds and plant your own in its place. You would rather let a child perish in ignorance than have it taught by a rival sectary. You can talk to me of the quintessential equality of coal merchants and British officers; and yet you can't see the quintessential equality of all the religions.
