In philosophy, spiritualism [a] is the concept, shared by a wide variety of systems of thought, that there is an immaterial reality that cannot be perceived by the senses. [3] This includes philosophies that postulate a personal God, the immortality of the soul, or the immortality of the intellect or will, as well as any systems of thought that assume a universal mind or cosmic forces lying beyond the reach of purely materialistic interpretations. [3]
Generally, any philosophical position, be it dualism, monism, atheism, theism, pantheism, idealism or any other, is compatible with spiritualism as long as it allows for a reality beyond matter. [3] [4] Theism is an example of a dualist spiritualist philosophy, while pantheism is an example of monist spiritualism. [4]
A particular form of spiritualism, frequently called neo-spiritualism, is that formulated by the French philosopher Jules Lachelier (CE 1834-1918), who was the teacher of the French philosophers Emile Boutroux (CE 1845-1921) and Henri Bergson (CE 1859-1941), both of whom are often also considered to exemplify neo-spiritualism. Lachelier advocated a form of spiritual realism whereby the spirit and spontaneity of humans provided an alternative to both idealism and materialism.
