Heredity (n.) is the psychiatrist's whole answer to a delusion — and "he is a rogue who gives more than he has."
Heredity (n.) is acquired experience too: dispositions were once the experiences of ancestors, and without acquisition there would be nothing to inherit.
Heredity (n.) can override personal experience: a child may come to fear his father as castrator though the threats came from women.
Heredity (n.) may be invoked in analysis only after the layers of individual experience have been dug through.
Heredity (n.) was for Charcot the only real cause of nervous illness, and Freud thought he overrated it.
Heredity (n.) works like a multiplier in an electric circuit: it decides how far the needle swings, not which way.
Heredity (n.) can scatter different nervous disorders across a family, and cannot explain why each member got the one he got.
Heredity (n.) and circumstance can stand in for each other in quantity: a heavy inheritance needs only a light blow, and a light one a heavy blow.
