Reproduction Quotes

“Five per cent vision is better than no vision at all. Five per cent hearing is better than no hearing at all. Five per cent flight efficiency is better than no flight at all. It is thoroughly believable that every organ or apparatus that we actually see is the product of a smooth trajectory through animal space, a trajectory in which every intermediate stage assisted survival and reproduction.”

“All the acquisitions or losses wrought by nature on individuals, through the influence of the environment in which their race has long been placed, and hence through the influence of the predominant use or permanent disuse of any organ; all these are preserved by reproduction to the new individuals which arise, provided that the acquired modifications are common to both sexes, or at least to the individuals which produce the young.”

“The succession of individuals, connected by reproduction and belonging to a species, makes it possible for the specific form itself to last for ages. In the end, however, the species is temporary; it has no "eternal life." After existing for a certain period, it either dies or is converted by modification into other forms.”

“It was to Hofmeister, working as a young man, an amateur and enthusiast, in the early morning hours of summer months, before business, at Leipzig in the years before 1851, that the vision first appeared of a common type of Life-Cycle, running through Mosses and Ferns to Gymnosperms and Flowering Plants, linking the whole series in one scheme of reproduction and life-history.”

“Our immediate interests are after all of but small moment. It is what we do for the future, what we add to the sum of man's knowledge, that counts most. As someone has said, 'The individual withers and the world is more and more.' Man dies at 70, 80, or 90, or at some earlier age, but through his power of physical reproduction, and with the means that he has to transmit the results of effort to those who come after him, he may be said to be immortal.”

“I am aware that the conclusions arrived at in this work will be denounced by some as highly irreligious; but he who denounces them is bound to show why it is more irreligious to explain the origin of man as a distinct species by descent from some lower from, through the laws of variation and natural selection, than to explain the birth of the individual through the laws of ordinary reproduction. The birth both of the species and of the individual are equally parts of that grand sequence of events, which our minds refuse to accept as the result of blind chance.”

“In trying to evaluate Hopkins' unique contribution to biochemistry it may perhaps be said that he alone amongst his contemporaries succeeded in formulating the subject. Among others whose several achievements in their own fields may have surpassed his, no one has ever attempted to unify and correlate biochemical knowledge so as to form a comprehensible picture of the cell and its relation to life, reproduction and function.”

“Cell genetics led us to investigate cell mechanics. Cell mechanics now compels us to infer the structures underlying it. In seeking the mechanism of heredity and variation we are thus discovering the molecular basis of growth and reproduction. The theory of the cell revealed the unity of living processes; the study of the cell is beginning to reveal their physical foundations.”

“I believe that now and always the conscious selection of the best for reproduction will be impossible; that to propose it is to display a fundamental misunderstanding of what individuality implies. The way of nature has always been to slay the hindmost, and there is still no other way, unless we can prevent those who would become the hindmost being born. It is in the sterilization of failure, and not in the selection of successes for breeding, that the possibility of an improvement of the human stock lies.”

“I suspect that religion is a necessary evil in the childhood of our particular species. And that's one of the interesting things about contact with other intelligences: we could see what role, if any, religion plays in their development. I think that religion may be some random by-product of mammalian reproduction. If that's true, would non-mammalian aliens have a religion?”

“Free election of masters does not abolish the masters or the slaves. Free choice among a wide variety of goods and services does not signify freedom if these goods and services sustain social controls over a life of toil and fear – that is, if they sustain alienation. And the spontaneous reproduction of superimposed needs by the individual does not establish autonomy; it only testifies to the efficacy of the controls.”

“The aim of jazz is the mechanical reproduction of a regressive moment, a castration symbolism. 'Give up your masculinity, let yourself be castrated,' the eunuchlike sound of the jazz band both mocks and proclaims, 'and you will be rewarded, accepted into a fraternity which shares the mystery of impotence with you, a mystery revealed at the moment of the initiation rite.”

“High quality water is more than the dream of the conservationists, more than a political slogan; high quality water, in the right quantity at the right place at the right time, is essential to health, recreation, and economic growth. Of all our planet's activities - geological movements, the reproduction and decay of biota, and even the disruptive propensities of certain species (elephants and humans come to mind) - no force is greater than the hydrologic cycle.”

“Man makes history; woman is history. The reproduction of the species is feminine: it runs steadily and quietly through all species, animal or human, through all short-lived cultures. It is primary, unchanging, everlasting, maternal, plantlike, and cultureless. If we look back we find that it is synonymous with life itself.”

“Homosexuality is not 'normal' On the contrary it is a challenge to the norm...Nature exists whether academics like it or not. And in nature, procreation is the single relentless rule. That is the norm. Our sexual bodies were designed for reproduction...No one is born gay. The idea is ridiculous...homosexuality is an adaptation, not an inborn trait.”

“The most refined skills of color printing, the intricate techniques of wide-angle photography, provide us pictures of trivia bigger and more real than life. We forget that we see trivia and notice only that the reproduction is so good. Man fulfils his dream and by photographic magic produces a precise image of the Grand Canyon. The result is not that he adores nature or beauty the more. Instead he adores his camera - and himself.”

“In no sense other than an utterly trivial one is reproduction the inverse of chemical disintegration. It is a misunderstanding of genetics to suppose that reproduction is only 'intended' to make facsimiles, for parasexual processes of genetical exchange are to be found in the simplest living things.”

“To use the image of Che Guevara to sell vodka is a slur on his name and memory. He never drank himself, he was not a drunk, and drink should not be associated with his immortal memory... As a supporter of the ideals for which Che Guevara died, I am not averse to its reproduction by those who wish to propagate his memory and the cause of social justice throughout the world.”

“Thus ordered thinking arises out of the ordered course of nature in which man finds himself, and this thinking is from the beginning nothing more than the subjective reproduction of the regularity according to the law of natural phenomena. On the other hand, this reproduction is only possible by means of the will that controls the concatenation of ideas.”

“The movements of nature are in a never ending circle. The animal species which has once been put into a train of motion, is still probably moving in that train. For if one link in nature's chain might be lost, another and another might be lost, till this whole system of things should evanish by piece-meal; a conclusion not warranted by the local disappearance of one or two species of animals, and opposed by the thousands and thousands of instances of the renovating power constantly exercised by nature for the reproduction of all her subjects, animal, vegetable, and mineral.”

“There is no more reason for a room on a stage to be a reproduction of an actual room than for an actor who plays the part of Napoleon to be Napoleon, or for an actor who plays Death in the old morality play to be dead.”

“I now believe that the universe was brought into existence by an infinite Intelligence. I believe that this universe's intricate laws manifest what scientists have called the Mind of God. I believe that life and reproduction originate in a divine Source. Why do I believe this, given that I expounded and defended atheism for more than a half century? The short answer is this: this is the world picture, as I see it, that has emerged from modern science.”

“Sexual reproduction exists solely as a means to defeat parasites. By mixing male and female genes, sex produces offspring not exactly like either the male or female - making each generation different from the last, and presenting a moving target to intruders intent on compromising this system. ... Even with this variation, parasites continue to pose a threat... and parasitism evolves and moves through any system - not just living things. The less variation there is in a system, the more readily parasites will evolve to infest it.”
