"An unpopular opinion concerning politics or religion lies concealed in the breast of every man; in many cases not only one sample, but several. The more intelligent the man, the larger the freightage of this kind of opinions he carries, and keeps to himself.

Twain is optimistic in his belief that most people restrain from vocalizing their true sentiments for the sake of conformity. I’d posit that most, in fact, do the opposite.
