Heredity Quotes

“Thanks to our cinctures and corsets we have succeeded in making an artificial being out of woman. She is an anomaly, and Nature herself, obedient to the laws of heredity, aids us in complicating and enervating her. We carefully keep her in a state of nervous weakness and muscular inferiority, and in guarding her from fatigue, we take away from her possibilities of development. Thus modeled on a bizarre ideal of slenderness to which, strangely enough, we continue to adhere, our women have nothing in common with us, and this, perhaps, may not be without grave moral and social disadvantages.”

“Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.”

“It is one of the many merits of this admirable biography of Proust's mother that it invites one to return to the novel with perhaps a fuller understanding of Proust's heredity, hinterland, and upbringing. . . . This fascinating book is full of interesting social and cultural observation, of information about French Jewish life, the position of Jews in society and, of course, the Dreyfus case. But it is essentially a study of one of the most remarkable and fruitful of mother-son relationships. As such it is a book that every Proustian will want to read.”

“You are not barred from attaining greatness by heredity. No matter who or what your ancestors may have been or how unlearned or lowly their station, the upward way is open for you. There is no such thing as inheriting a fixed mental position; no matter how small the mental capital we receive from our parents, it may be increased; no man is incapable of growth.”

“When it comes to explaining human thought and behavior, the possibility that heredity plays any role at all still has the power to shock. To acknowledge human nature, many think, is to endorse racism, sexism, war, greed, genocide, nihilism, reactionary politics, and neglect of children and the disadvantaged. Any claim that the mind has an innate organization strikes people not as a hypothesis that might be incorrect but as a thought it is immoral to think.”

“Increasingly, our leaders must deal with dangers that threaten the entire world, where an understanding of those dangers and the possible solutions depends on a good grasp of science. The ozone layer, the greenhouse effect, acid rain, questions of diet and heredity. All require scientific literacy. Can Americans choose the proper leaders and support the proper programs if they themselves are scientifically illiterate? The whole premise of democracy is that it is safe to leave important questions to the court of public opinion - but is it safe to leave them to the court of public ignorance?”

“Training- training is everything; training is all there is to a person. We speak of nature; it is folly; there is no such thing as nature; what we call by that misleading name is merely heredity and training. We have no thoughts of our own, no opinions of our own; they are transmitted to us, trained into us.”
