B. W. Betts - Antique Diagrams showing the Stages of Human Consciousness, “Geometrical psychology”, 1887.
In his metaphysical explorations, Betts attempted to represent the successive stages of the evolution of human consciousness with symbolic mathematical forms; he was quite pleased to find that his mathematical representations frequently resulted in plant-like forms, taking this to mean that he was on the track to some universal representation of consciousness. Incidentally, he also believed that human consciousness was the only thing that we as humans could study directly since everything else must necessarily be perceived through human consciousness.
