You cannot change the conclusion of the brain by torture; nor by social ostracism. But I will tell you what you can do by these, and what you have done. You can make hypocrites by the million. You can make a man say that he has changed his mind; but he remains of the same opinion still. Put fetters all over him; crush his feet in iron boots; stretch him to the last gasp upon the holy rack; burn him, if you please, but his ashes will be of the same opinion still.
The Liberty of Man, Woman and Child (1877)
