The article discusses how the concept of personal unity in transcendental philosophy has influenced traditional philosophical ideas. It argues that real existence belongs only to the divine existence, while everything else is just a manifestation of it.

This new approach sees the existence of God manifested through various aspects and forms. By shifting their philosophical view, the author reintroduces the principle of causality as a theory of divine manifestation.
