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. The only case in which the higher ground has been taken on principle and maintained with consistency, by any but an individual here and there, is that of religious belief: a case instructive in many ways, and not least so as forming a most striking instance of the fallibility of what is called the moral sense: for the _odium theologicum_, in a sincere bigot, is one of the most unequivocal cases of moral feeling. Those who first broke the yoke of what called itself the Universal Church, were in general as little willing to permit difference of religious opinion as that church itself. But when the heat of the conflict was over, without giving a complete victory to any party, and each church or sect was reduced to limit its hopes to retaining possession of the ground it already occupied; minorities, seeing that they had no chance of becoming majorities, were under the necessity of pleading to those whom they could not convert, for permission to differ. It is accordingly on this battle-field, almost solely, that the rights of the individual against society have been asserted on broad grounds of principle, and the claim of society to exercise authority over dissentients, openly controverted. The great writers to whom the world owes what religious liberty it possesses, have mostly asserted freedom of conscience as an indefeasible right, and denied absolutely that a human being is accountable to others for his religious belief. Yet so natural to mankind is intolerance in whatever they really care about, that religious freedom has hardly anywhere been practically realised, except where religious indifference, which dislikes to have its peace disturbed by theological quarrels, has added its weight to the scale. In the minds of almost all religious persons, even in the most tolerant countries, the duty of toleration is admitted with tacit reserves. One person will bear with dissent in matters of church government, but not of dogma; another can tolerate everybody, short of a Papist or a Unitarian; another, every one who believes in revealed religion; a few extend their charity a little further, but stop at the belief in a God and in a future state.
