Luther Burbank Quotes

The mere crossing of species, unaccompanied by selection, wise supervision, intelligent care, and the utmost patience, is not likely to result in marked good, and may result in vast harm. Unorganized effort is often most vicious in its tendencies.

No one at all understands why it is possible for the plant cell that bears within its substance one of these green bodies to combine certain inorganic elements into nutritious foods, a feat that no human chemist can perform.

Those who are making history seldom have time to record it.

Do not be cross with the child; you cannot afford it. If you are cultivating a plant, developing it into something finer and nobler, you must love it, not hate it; be gentle with it, not abusive; be firm, never harsh. I give the plants upon which I am at work in a test, whether a single one or a hundred thousand, the best possible environment. So should it be with a child, if you want to develop it in right ways. Let the children have music, let them have pictures, let them have laughter, let them have a good time; not an idle time but one full of cheerful occupation. Surround them with all the beautiful things you can. Plants should be given sun and air and the blue sky; give them to your boys and girls. ...for all the years. We cannot treat a plant tenderly one day and harshly the next; they cannot stand it. Remember that you are training not only for to-day, but for all the future, for all posterity.

The essential basis of life itself, namely, , is a substance composed largely of water and having the physical constitution of a viscid liquid.

The plant laboratories in which this wonderful and vitally essential transformation is effected are chiefly located in the leaf of the plant... the thoughtful person must regard this structure—the most ordinary green leaf of tree or shrub or vine or the tiniest blade of grass—as in some respects the most wonderful thing in the world.

A knowledge of Mendelism is recognized by me as only the ABC to the broader knowledge of heredity necessary for success in animal and plant improvement, and all variations and all mutations of every nature are responses to environment which, by repetition and combination, are slowly but surely fixed in heredity and at last made tangible, most often through the crossing of varieties, species, or genera, either by nature or that part of nature called man.

When certain hereditary tendencies are almost indelibly ingrained, environment will have a hard battle to effect a change in the child; but that a change can be wrought by the surroundings we all know. The particular subject may at first be stubborn against these influences, but repeated application of the same modifying forces in succeeding generations will at last accomplish the desired object in the child as it does in the plant.

Here appears a child plainly not normal, what shall we do with him? Shall we, as some have advocated, even from Spartan days, hold that the weaklings should be destroyed? No. In cultivating plant life, while we destroy much that is unfit, we are constantly on the lookout for what has been called the abnormal, that which springs apart in new lines. How many plants are there in the world to-day that were not in one sense once abnormalities? No; it is the influence of cultivation, of selection, of surroundings, of environment, that makes the change from the abnormal to the normal. From the children we are led to call abnormal, may come, under wise cultivation and training, splendid normal natures.

Let me lay emphasis on the opportunity now presented in the United States for observing and, if we are wise, aiding in what I think it fair to say is the grandest opportunity ever presented of developing the finest race the world has ever known out of the vast mingling of races brought here by immigration.

The most interesting thing in the world, from the standpoint of animal economy—which of course includes human economy—is the wonderful laboratory or factory of the plant...

To the gardener who goes about his task with the right spirit must every plant appear as the most wonderful of laboratories in which miracles of transformation, outmatching the utmost feats of the most skillful conjurer, are being performed every hour.

There is not a single desirable attribute which, lacking in a plant, may not be bred into it. Choose what improvement you wish in a flower, a fruit, or a tree, and by crossing, selection, cultivation, and persistence you can fix this desirable trait irrevocably.

Heredity is not the dark specter which some people have thought—merciless and unchangeable, the embodiment of Fate itself. This dark, pessimistic belief which tinges even the literature of to-day comes, no doubt, from the general lack of knowledge of the laws governing the interaction of these two ever-present forces of heredity and environment wherever there is life.
My own studies have led me to be assured that heredity is only the sum of all past environment, in other words environment is the architect of heredity; and I am assured of another fact: acquired characters are transmitted and—even further—that all characters which are transmitted have been acquired...

But with those who are mentally defective—ah, here is the hardest question of all!—what shall be done with them? ...In the case of human beings in whom the light of reason does not burn... shall they be eliminated from the race? Go to the mother of an imbecile child and get your answer. ...For these helpless unfortunates, as with those who are merely unfortunate from environment, I should enlist the best and broadest state aid.
