"Those only are happy .... who have their minds fixed on some object other than their own happiness, "a crisis in my mental history - John Stuart Mill

The only freedom which deserves the name is that of pursuing our own happiness in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it.

John Stuart Mill
1806-1873

The idea that truth always triumphs over persecution is one of those pleasant falsehoods, which most experience refutes. History is teeming with instances of truth put down by persecution. If not put down forever, it may be set back for centuries.

[For people] to refuse a hearing to an opinion, because they are sure that it is false, is to assume that their certainty is the same thing as absolute certainty. All silencing of discussion is an assumption of infallibility.
