Increased knowledge of heredity means increased power of control over the living thing, and as we come to understand more and more the architecture of the plant or animal we realize what can and what cannot be done towards modification or improvement.
Good heredity and environment are necessary. You cannot compare the child of a savage with the child of a civilized person.
Everyone is the heir to all that has gone before; his structure and emotional life is fixed, and no two children of nature have the same heredity. I believe everyone should and must live out what is in him. So no two lives can be the same.
Heredity proposes and development disposes.
Heredity is a splendid phenomenon that relieves us of responsibility for our shortcomings.
For better or worse, you must play your own little instrument in the orchestra of life.
The precise form of an individual's activity is determined, of course, by the equipment with which he came into the world. In other words, it is determined by his heredity.
I believe a unique core self is born into every human being; the result of millennia of environment and heredity combined in an unpredictable way that could never happen before or again.
Life consists not simply in what heredity and environment do to us, but in what we make out of what they do to us
I am the beneficiary of a lucky break in the genetic sweepstakes.
All Congresses and Parliaments have a kindly feeling for idiots, and a compassion for them, on account of personal experience and heredity.
We live in a dancing matrix of viruses; they dart, rather like bees, from organism to organism, from plant to insect to mammal to me and back again, and into the sea, tugging along pieces of this genome, strings of genes from that, transplanting grafts of DNA, passing around heredity as though at a great party.
We do not know, in most cases, how far social failure and success are due to heredity, and how far to environment. But environment is the easier of the two to improve.
The man of the future may, and even must, do things impossible in the past and acquire new motor variations not given by heredity.
Heredity is what sets the parents of a teenager wondering about each other.
Acceptance of one's life has nothing to do with resignation; it does not mean running away from the struggle. On the contrary, it means accepting it as it comes, with all the handicaps of heredity, of suffering, of psychological complexes and injustices.
Religion shows a pattern of heredity which I think is similar to genetic heredity. ... There are hundreds of different religious sects, and every religious person is loyal to just one of these. ... The overwhelming majority just happen to choose the one their parents belonged to. Not the sect that has the best evidence in its favour, the best miracles, the best moral code, the best cathedral, the best stained-glass, the best music when it comes to choosing from the smorgasbord of available religions, their potential virtues seem to count for nothing compared to the matter of heredity.
The whelp of a wolf must prove a wolf at last, notwithstanding he may be brought up by a man.
The philosophical implication of race-thinking is that by offering us the mystery of heredity as an explanation, it diverts our attention from the social and intellectual factors that make up personality.
The advances of biology during the past 20 years have been breathtaking, particularly in cracking the mystery of heredity. Nevertheless, the greatest and most difficult problems still lie ahead. The discoveries of the 1970's about the chemical roots of memory in nerve cells or the basis of learning, about the complex behavior of man and animals, the nature of growth, development, disease and aging will be at least as fundamental and spectacular as those of the recent past.
That the fundamental aspects of heredity should have turned out to be so extraordinarily simple supports us in the hope that nature may, after all, be entirely approachable. Her much-advertised inscrutability has once more been found to be an illusion due to our ignorance. This is encouraging, for, if the world in which we live were as complicated as some of our friends would have us believe we might well despair that biology could ever become an exact science.
This missing science of heredity, this unworked mine of knowledge on the borderland of biology and anthropology, which for all practical purposes is as unworked now as it was in the days of Plato, is, in simple truth, ten times more important to humanity than all the chemistry and physics, all the technical and indsutrial science that ever has been or ever will be discovered.
If a given scientist had not made a given discovery, someone else would have done so a little later. Johann Mendel dies unknown after having discovered the laws of heredity: thirty-five years later, three men rediscover them. But the book that is not written will never be written. The premature death of a great scientist delays humanity; that of a great writer deprives it.
Heredity is to-day the central problem of biology. This problem may be approached from many sides - that of the breeder, the experimenter, the statistician, the physiologist, the embryologist, the cytologist - but the mechanism of heredity can be studied best by the investigation of the germ cells and their development.
Nothing is so soothing to our self-esteem as to find our bad traits in our forebears. It seems to absolve us.
