The ground of Liberalism so understood is certainly not the view that a man's personal opinions are socially indifferent, nor that his personal morality matters nothing to others. So far as Mill rested his case on the distinction between self-regarding actions and actions that affect others, he was still dominated by the older individualism. We should frankly recognize that there is no side of a man's life which is unimportant to society, for whatever he is, does, or thinks may affect his own well-being, which is and ought to be matter of common concern, and may also directly or indirectly affect the thought, action, and character of those with whom he comes in contact. The underlying principle may be put in two ways. In the first place, the man is much more than his opinions and his actions. Carlyle and Sterling did not differ "except in opinion." To most of us that is just what difference means. Carlyle was aware that there was something much deeper, something that opinion just crassly formulates, and for the most part formulates inadequately, that is the real man. The real man is something more than is ever adequately expressed in terms which his fellows can understand; and just as his essential humanity lies deeper than all distinctions of rank, and class, and colour, and even, though in a different sense, of sex, so also it goes far below those comparatively external events which make one man figure as a saint and another as a criminal. This sense of ultimate oneness is the real meaning of equality, as it is the foundation of social solidarity and the bond which, if genuinely experienced, resists the disruptive force of all conflict, intellectual, religious, and ethical.
