"The likings and dislikings of society, or of some powerful portion of it, are thus the main thing which has practically determined the rules laid down for general observance, under the penalties of law or opinion. And in general, those who have been in advance of society in thought and feeling, have left this condition of things unassailed in principle, however they may have come into conflict with it in some of its details. They have occupied themselves rather in inquiring what things society ought to like or dislike, than in questioning whether its likings or dislikings should be a law to individuals. They preferred endeavouring to alter the feelings of mankind on the particular points on which they were themselves heretical, rather than make common cause in defence of freedom, with heretics generally.
