On every hand are the enemies of individuality and mental freedom. Custom meets us at the cradle and leaves us only at the tomb. Our first questions are answered by ignorance, and our last by superstition. We are pushed and dragged by countless hands along the beaten track, and our entire training can be summed up in the word –suppression. Our desire to have a thing or to do a thing is considered as conclusive evidence that we ought not to have it, and ought not to do it. At every turn we run against cherubim and a flaming sword guarding some entrance to the Eden of our desire. We are allowed to investigate all subjects in which we feel no particular interest, and to express the opinions of the majority with the utmost freedom. We are taught that liberty of speech should never be carried to the extent of contradicting the dead witnesses of a popular superstition. Society offers continual rewards for self-betrayal, and they are nearly all earned and claimed, and some are paid.
