Abstract
Henri Delacroix is a French philosopher, religious scholar and psychologist, a student and follower of Bergson. He began his activity with the study of mysticism. Following the thesis “An Essay on Speculative Mysticism in Germany in the 14th Century”, where the author analyzed the teachings of Meister Eckhart and the associated intellectual movement, he published several other works where he examined other historical and national forms of mysticism. Describing different types of mystical intuition, conducting a detailed psychological analysis, Delacroix interpreted the higher forms of mystical experience, contrary to the opinions of some researchers, as an expression of deep inner life and not as a special type of neurosis. His work Studies in the History and Psychology of Mysticism: the Great Christian Mystics was highly appreciated by contemporaries, and the approach he proposed to this subject gradually gained recognition and became classical. In his philosophical and psychological works, Delacroix acted as an opponent of associationism and mental atomism. He developed the treatment of consciousness as an entity, considering the various forms and manifestations of consciousness and the unconscious in their interconnection and mutual influence. He paid special attention to the relationship between language and thinking as well as child psychology and the psychology of art. In his book Language and Thinking, Delacroix, relying on the concept of F. de Saussure, developed the distinction of language and speech proposed by the latter.
