Dream and Reality (1949)
Context: There is no objective reality. But there is only an illusion of consciousness, there is only an objectivication of reality, which was created by the spirit. The origin of life is creativity, freedom; and the personality, subject, and spirit are the representatives of that origin, but not the nature, not the object.

The Undiscovered Self (1958)

Materialism and Empirio-Criticism (1908)
In Search of the Miraculous (1949)
Context: Objective knowledge, the idea of unity included, belongs to objective consciousness. The forms which express this knowledge when perceived by subjective consciousness are inevitably distorted and, instead of truth, they create more and more delusions. With objective consciousness it is possible to see and feel the unity of everything. But for subjective consciousness the world is split up into millions of separate and unconnected phenomena. Attempts to connect these phenomena into some sort of system in a scientific or philosophical way lead to nothing because man cannot reconstruct the idea of the whole starting from separate facts and they cannot divine the principles of the division of the whole without knowing the laws upon which this division is based.
