Variation Quotes
Throughout his last half-dozen books, for example, Arthur Koestler has been conducting a campaign against his own misunderstanding of Darwinism. He hopes to find some ordering force, constraining evolution to certain directions and overriding the influence of natural selection. [...] Darwinism is not the theory of capricious change that Koestler imagines. Random variation may be the raw material of change, but natural selection builds good design by rejecting most variants while accepting and accumulating the few that improve adaptation to local environments.
Stephen Jay Gould
As a means of variation from a normal type, sickness in childhood ought to have a certain value not to be classed under any fitness or unfitness of natural selection; and especially scarlet fever affected boys seriously, both physically and in character, though they might through life puzzle themselves to decide whether it had fitted or unfitted them for success.
Henry Adams
If you look at any leaf on any tree branch, it's similar to but not exactly a repetition of the previous branch. So the new science of complexity or showing how an architecture can be produced just as quickly, cheaply and efficiently by using computer production methods to get the slight variation, the self-similarity.
Charles Jencks
Owing to this struggle for life, any variation, however slight and from whatever cause proceeding, if it be in any degree profitable to an individual of any species, in its infinitely complex relations to other organic beings and to external nature, will tend to the preservation of that individual, and will generally be inherited by its offspring.
Charles Darwin
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...
Daniel Suarez
I make a little mystique for myself. Since I have no preference or so-called sense of color, I could take almost everything that could be some accident of a previous painting. Or I set out to make a series. I take, for instance, some pictures where I take a color, some arbitrary color I took from some place. Well, this is gray maybe, and I mix the color for that, and then I find out that when I am through with getting the color the way I want it, I have six other colors in it, to get that color; and then I take those six colors and I use them also with this color. It is probably like a composer does a variation on a certain theme. But it isn't technical, it isn't just fun.
Willem de Kooning
Instruction, that mysterious communing of Wisdom with Ignorance, is no longer an indefinable tentative process, requiring a study of individual aptitudes, and a perpetual variation of means and methods, to attain the same end; but a secure, universal, straightforward business, to be conducted in the gross, by proper mechanism.
Thomas Carlyle
Evolution must have involved the simultaneous change in many genes, which doubtless accounts for its slowness. Here matters would have been easier if heritable variations really formed a continuum, as Darwin apparently thought, i.e. if there were no limit to the possible smallness of a variation. But this is clearly not the case when we are considering meristic characters. ...the atomic nature of Mendelian inheritance suggests very strongly that even where variation is apparently continuous this appearance is deceptive.
J. B. S. Haldane
This book [Zen in the Art of Archery], by Herrigel, which I discovered a few years ago, seems to me fundamental to our profession as photographers. Matisse wrote similarly about drawing: set a discipline, make rigor a rule, forget oneself completely. And in photography the attitude must be the same: detach oneself, do not try to prove anything at all. My sense of freedom is the same: a frame that allows any variation. This is the basis of Zen Buddhism, the evidence: that you go in with great force and then you succeed in forgetting yourself.
Henri Cartier-Bresson
If I have to hire a labourer for a week, and instead of ten shillings I pay him eight, no variation having taken place in the value of money, the labourer can probably obtain more food and necessaries with his eight shillings than he before obtained for ten: but this is owing, not to a rise in the real value of his wages, as stated by Adam Smith, and more recently by Mr. Malthus, but to a fall in the value of the things on which his wages are expended, things perfectly distinct; and yet for calling this a fall in the real value of wages, I am told that I adopt new and unusual language, not reconcilable with the true principals of the science. To me it appears that the unusual and, indeed, inconsistent language is that used by my opponents.
