The occult consists of a mixed aggregate of movements and doctrines, which may be the expressions of kindred interests and dispositions, but present no essential community of content. Such members of this cluster of beliefs as in our day and generation have attained a considerable adherence or still retain it from former generations, constitute the modern occult. A conspicuous and truly distinctive characteristic of the occult is its marked divergence in trend and belief from the recognized standards and achievements of human thought. This divergence is one of attitude and logic and general perspective. It is a divergence of intellectual temperament, that distorts the normal reactions to science and evidence, and to the general significance and values of the factors of our complicated natures and of our equally complicated environment. At least it is this in extreme and pronounced forms; and shades from it through an irregular variety of tints to a vague and often unconscious susceptibility for the unusual and eccentric, combined with an instability of conviction regarding established beliefs that is more often the expression of the weakness of ignorance than of the courage of independence. In their temper and course of unfoldment, occult doctrines are likely to involve and to proceed upon mysticism, obscurity, and a disguised form of superstition. In their content, they are attracted to such themes as the ultimate nature of mental action, the conception of life and death, the effect of cosmic conditions upon human events and endowment, the delineation of character, the nature and treatment of disease; or indeed to any of the larger or smaller realms of knowledge that combine with a strong human, and at times a practical interest, a considerable complexity of basal principles and general relations. Both the temper and the content, the manner and the matter of the occult, should be borne in mind in a survey of its more distinctive examples. It is well, while observing the particular form of occultism or mysticism, or, it may be, merely of superstition and error, which one or another of the occult movements exhibits, to note as well the importance of the intellectual motive or temperament that inclines to the occult. It is important to inquire not only what is believed, but what is the nature of the evidence that induces belief; to observe what attracts and then makes converts; to discover what are the influences by which the belief spreads. Two classes of motives or interests are conspicuous: the one prominently intellectual or theoretical, the other moderately or grossly practical. Movements in which the former interest dominates, contain elements that command respect even when they do not engage sympathy; and that appeal, though it may be unwisely, to worthy impulses and lofty aspirations. Amongst the movements presenting prominent practical aspects are to be found instances of the most
