The Intuitional School of Moralists finds the intuitions as to what is right and wrong, and more especially the feeling of right and the feeling of wrong, justified and established in the fact of the growth of feeling in general as the essential of the biological history, and in the historical establishment of the internal growth of moral feelings transmitted from generation to generation. Validity and authority are given, to moral principles by the very fact of their existing strength and their recognised fitness to the social circumstances. The indignation or the admiration naturally felt by man at certain actions is justified _a priori_, and apart from any reasoned opinion of their bearings. Praise and blame are not much, as a matter of fact, affected by reason. Spontaneously and independently passion and enthusiasm are expressed. Without staying to think, comes the unbidden frown and sharp reproof, or even the hasty blow. Without thought come the expression of sorrow and sympathy, the glow of praise, the approving smile, the commendatory word, straight from the heart and sympathies of the like-minded spectator. Reason may argue about details--it may rejudge the spontaneous expressions of the sympathies, it may guide and direct, but it never lends to praise its warmth, or to condemnation its severity. These are purely instinctive, and reason justifies them in the ascertainment of their origin and growth. There is an intuitive conscience which has been developed by evolution. The adjustment of organisms, the growth of feeling, the acquisition of altruistic or sympathetic feeling in an environment of subjective individuals has developed not only social adjustments, but also feelings in individuals, relative to those social adjustments, which compose a conscience or intuition. Never yet could such a conscience or intuition wholly and of itself teach a man moral action. The conscience presupposes for its actualization the presence of its environment. It needs education, encouragement, and instruction. Society is a continuous existence. The child born into a society not only inherits its dispositions, but from the very first receives its prepossessions, is subject to its injunctions, and is trained in its habits. Intuition is only a part of the truth. Yet although it may be developed by education, and guided by reason, there is no question as to its existence, and as to its affording the zest to praise, the keenness to condemnation, and the poignancy to remorse.
