Spiritualism (philosophy)

In philosophy, spiritualism 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. 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.
