Instinct (n.) is like nature herself prodigiously conservative, and yet transcending her own historical conditions in her acts of creation.
Instinct (n.) is nature that seeks to perpetuate nature. It contrasts itself with consciousness which is nothing other than man's turning away from and opposing himself to instinct in favor of culture.
Instinct (n.) is a concept on the frontier between the somatic and the mental — the psychic representative of organic forces.
Instinct (n.) storming in becomes an encounter with the divine — so long as man does not follow it blindly but defends his humanity against the god's animal nature, like Jacob wrestling the angel.
Instinct (n.) cannot be abolished by decision; changing it takes the slow organic work of many generations.
Instinct (n.) needs a counterpart: a purposive act presupposes a meaningful grasp of the situation, and the inherited primordial image is that grasp.
Instinct (n.) is every psychic process whose energy is not under conscious control — so even willed acts become instinctive when fatigue or intoxication lowers the mental level.
Instinct (n.) dammed up in civilized man is far more destructive than in the primitive, who lives his negative instinct out in modest doses — which is why no war of the past rivals the wars of civilized nations.
Instinct (n.) that is weak breeds one-sidedness: whoever strays from the family type loses the security of inherited instinct and clings to a single attitude.
Instinct (n.) does not only unite men; the instinct of self-preservation can drive a man into absolute isolation, aloof from the herd and upheld by loathing.
Instinct (n.) properly recognized leads the young person into life and entangles him with fate — and the sacrifices that follow are what form his character.
Instinct (n.) is lost less by atrophy than as a lasting product of education — a loss necessary for civilized man, since instincts at full strength would make social life almost impossible.
Instinct (n.) undergoes psychization: the psyche receives the raw biological stimulus and remoulds it, as the colour we see differs from the wavelength that produces it.
Instinct (n.) that has undergone too much psychization takes its revenge as an autonomous complex — one of the chief causes of neurosis.
Instinct (n.) is a natural push toward certain acts with no goal in view, no deliberation, and no idea of what we are doing, says Thomas Reid.
Instinct (n.) is an interruption in the continuity of consciousness, felt as inner necessity — and as boring to bet on as tomorrow's sunrise.
Instinct (n.) cannot all be learned habit: the yucca moth kneads a pellet of pollen, cuts open the pistil of a flower open one night only, lays its eggs and stuffs the pellet in — once in its life.
Instinct (n.) are typical modes of action: wherever action and reaction recur uniformly and regularly, instinct is at work — whether or not a conscious motive is attached.
Instinct (n.) and apprehension cannot be put in order: we cannot say whether grasping the situation or the impulse to act comes first — they are two faces of one vital activity.
Instinct (n.) may mask a direction other than biological, which shows itself only in the course of development — its meaning is not unambiguous.
