Note 147 — Chapter VII

In the other spheres in which symbolism most tends to appear, the same or allied conditions exist. In hallucinations, which (as Parish and others have shown) tend to occur in hypnagogic or sleep-like states, the conditions are clearly the same. The symbolism of an art, and notably music, is due to the very conditions of the art, which exclude any appeal to other senses. The primitive mind reaches symbolism through a similar condition of things, coming as the result of ignorance and undeveloped powers of apperception. In insanity these powers are morbidly disturbed or destroyed, with the same result.
