European theism and spiritualism of the XIX century and Russian religious philosophy are examples of a non-psychoanalytic tradition of studying the unconscious, the study of which is of scientific interest. The issue of the influence of European philosophy on Russian philosophy has been considered in many aspects, but the influence on the doctrine of the unconscious has not been studied. The aim of this article is to study the influence of the views of European theists and spiritualists of the XIX century on the problem of the unconscious on Russian religious philosophy. The novelty lies in the fact that, firstly, an assessment is given of the nature of the influence of European theism and spiritualism of the XIX century on Russian religious philosophy on the issue of the unconscious; secondly, the difference in the interpretation of the unconscious in religious philosophy of the XIX – first half of the XX century and psychoanalytic philosophy is shown. It is shown that European theism and spiritualism of the XIX century had a significant influence on the interpretation of the unconscious in Russian religious philosophy, however, domestic thinkers also, when studying the unconscious, focused their attention on the moral and ethical aspect of personal existence and considered the unconscious in a broad historical and philosophical context. In addition, the fundamental elements in the interpretation of the unconscious in Russian religious philosophy and European theism and spiritualism are the psychological understanding of the unconscious and the personal nature of the interaction between man and God (in accordance with the views of theistic philosophy).
