To sum up these relations of the viscera, the endocrines, the unconscious and the mind, it may be stated as a far-reaching generality for the understanding of human life: that character and conduct are expressions of the streams of energy arising in the vegetative apparatus, primarily endocrine determined at birth, and secondarily experience determined after the organism has learned to react as a whole, as consciousness.

The waves of feeling which precede them are unquestionably endocrine determined.
