It is true that nothing comes out of nothing, but their idea is that as the human being is the flower of this tree of manifestation, intelligence must have developed gradually through the mineral, vegetable, and animal kingdoms until it manifested more fully in man. But how can matter develop into intelligence? It is intelligence which is the source of all, but it is the captivity of intelligence in matter which we see; that is why it seems to us that manifestation begins from matter, and as it manifests in man we think man is a development of matter.
