C. Bradlaugh, quoted in Hypatia Bradlaugh Bonner’s Penalties Upon Opinion (1934):
Laws to punish differences of opinion are as useless as they are monstrous. Differences of opinion on politics are denounced and punished as seditious, on religious topics as blasphemous, and on social questions as immoral and obscene. Yet the sedition, blasphemy, and immorality punished in one age are often found to be the accepted, and sometimes the admired, political, religious, and social teaching of a more educated period. Heresies are the evidence of some attempt on the part of men to find opinions for themselves.
