Note 590 — Chapter VI

If we ask how it happens that one individual or another is degenerate, we must answer that very often this degeneracy is due to heredity, either in part or altogether. But if we enquire into the causes of degeneracy in general heredity ceases to be a cause. As Professor Dallemagne says: “Heredity creates nothing; from heredity to heredity we must still go back to the cause.”590
