There are higher, less materialistic forms: the collective excitement of pilgrimages and revivals, where the emotion of each individual is increased by that of the rest; the artificial means, known from antiquity, of attaining ecstasy, _i.e._, full possession; the frequent confusion, which has so often excited the wrath of theologians, between the language of carnal and that of mystical love.[198] ----- Footnote 198: For many original and quoted observations showing the close connection between the sexual and religious emotions, see the recent series of valuable papers by Vallon and Marie, “Des Psychoses Religieuses,” _Archives de Neurologie_, 1897.—ED. ----- All these facts are well known, and thousands of others are recorded in history. It is convenient to recall them in order to show that they have their psychological reasons; they are not aberrations, as might seem to be the case at first sight, but the necessary conditions of intense emotion. If it is objected that some of them border on madness, we may reply that every violent passion does the same, and sometimes crosses the border-line. (_b._) The religious sentiment, again, is attached to material conditions by its mode of expression, which is ritual. Ritual practices are not, as many think, purely exterior and artificial, accessory and adventitious; they are a spontaneous creation, originating in the nature of things. Every religion, great or insignificant, is an organism constituted by a fundamental belief attached to percepts, images, or concepts, _plus_ certain secondary notions which are sometimes mutually contradictory, _plus_ an emotional state. All this forms a living whole, which evolves, vegetates, or retrogrades. This organic character distinguishes the positive religions from the purely theoretical and metaphysical conceptions, which are not alive, never have lived, and are nothing but pure speculation. Now, as every animal organism, from the infusoria to man, has its relational life,—_i.e._, relations with external agents,—so religion, as an organism, has its life of relations with the supernatural and mysterious powers on which man believes himself to be dependent. This life is expressed by rites, which are means of action, methods of establishing a relation. The history of ritual is a chapter of the expression of the emotions. The only difference is this: emotional expression, in the sense given to the words by Duchenne, Darwin, their successors, and the world in general, has an individualist character, showing fear, anger, love, etc.; while ritual expression has a _social_ character; being the spontaneous product of a collectivity, of a group, which has become fixed and permanent, erected into an institution by the influence of society, and safeguarded by tradition. On this subject I cannot enter into detail; it is sufficient to remind the reader that ritual is psychic in its origin. There have been two principal phases in its development.
