Variation Quotes - page 2
[A]lthough species may be discrete, they have no immutable essence. Variation is the raw material of evolutionary change. It represents the fundamental reality of nature, not an accident about a created norm. Variation is primary; essences are illusory. Species must be defined as ranges of irreducible variation.
Stephen Jay Gould
We have always thought that Mr. Darwin has unnecessarily hampered himself by adhering so strictly to his favourite "Natura non facit saltum." We greatly suspect that she does make considerable jumps in the way of variation now and then, and that these saltations give rise to some of the gaps which appear to exist in the series of known forms.
Thomas Henry Huxley
And yet I think that the Full House model does teach us to treasure variety for its own sake-for tough reasons of evolutionary theory and nature's ontology, and not from a lamentable failure of thought that accepts all beliefs on the absurd rationale that disagreement must imply disrespect. Excellence is a range of differences, not a spot. Each location on the range can be occupied by an excellent or an inadequate representative-and we must struggle for excellence at each of these varied locations. In a society driven, often unconsciously, to impose a uniform mediocrity upon a former richness of excellence-where McDonald's drives out the local diner, and the mega-Stop & Shop eliminates the corner Mom and Pop-an understanding and defense of full ranges as natural reality might help to stem the tide and preserve the rich raw material of any evolving system: variation itself.
Stephen Jay Gould
But, as we consider the totality of similarly broad and fundamental aspects of life, we cannot defend division by two as a natural principle of objective order. Indeed, the "stuff” of the universe often strikes our senses as complex and shaded continua, admittedly with faster and slower moments, and bigger and smaller steps, along the way. Nature does not dictate dualities, trinities, quarterings, or any "objective” basis for human taxonomies; most of our chosen schemes, and our designated numbers of categories, record human choices from a cornucopia of possibilities offered by natural variation from place to place, and permitted by the flexibility of our mental capacities. How many seasons (if we wish to divide by seasons at all) does a year contain? How many stages shall we recognize in a human life?
Stephen Jay Gould
A small beginning has led us to a great ending. If I were to put the bit of chalk with which we started into the hot but obscure flame of burning hydrogen, it would presently shine like the sun. It seems to me that this physical metamorphosis is no false image of what has been the result of our subjecting it to a jet of fervent, though nowise brilliant, thought to-night. It has become luminous, and its clear rays, penetrating the abyss of the remote past, have brought within our ken some stages of the evolution of the earth. And in the shifting "without haste, but without rest" of the land and sea, as in the endless variation of the forms assumed by living beings, we have observed nothing but the natural product of the forces originally possessed by the substance of the universe.
Thomas Henry Huxley
Some days I have to give right in to the blues
Despite how I try to keep fightin'.
It's a sure shot I'm going to lose.
And I'll tell you why.
You think I'm crazy.
It's such a sad composition.
But can you blame me
For what's been causing my bad disposition?
Ain't nothing new with my blue situation
And nothing's fine it's just a minor variation.
Billy Joel
We contrast the urban and the natural, but that's a contemporary myth. We're animals, after all; our cities are organic products, fully as "natural” (whatever that word really means) as a termite hill or a rabbit warren. But how much more interesting: how much more complex, dressed in the intricacies and exfoliations of human culture, simple patterns iterated into infinite variation. And full of secrets, secrets beyond counting.
Robert Charles Wilson
As an auxiliary to all of this,” he said, "I have found myself speculating upon a world in which no one ever grew up. I admit, of course, that it is a rather acrobatic feat of thinking, not entirely consistent, to leap from the one idea to the other. In a world where one was able to package his experiences, he merely would be able to relive at some future time the experiences of the past. But in a world of the eternally young he'd have no need of such packaging. Each new day would bring the same freshness and the everlasting wonder inherent in the world of children. There would be no realization of death and no fear born of the knowledge of the future. Life would be eternal and there'd be no thought of change. One would exist in an everlasting matrix and while there would be little variation from one day to the next, one would not be aware of this and there'd be no boredom...
Clifford D. Simak
I well remember receiving from one of the most earnest of my seniors the friendly warning that it was waste of time to study variation, for "Darwin had swept the field." Parenthetically we may notice that though scientific opinion in general became rapidly converted to the doctrine of pure selection, there was one remarkable exception. Systematists for the most part kept aloof. Everyone was convinced that natural selection operating in a continuously varying population was a sufficient account of the origin of species except the one class of scientific workers whose labours familiarised them with the phenomenon of specific difference. From that time the systematists became, as they still in great measure remain, a class apart.
William Bateson
That's all window dressing. That's not fundamental. That's not getting at change and the transformation that must take place. Sure we have to solve problems. Certainly stamp out the fire. Stamp out the fire and get nowhere. Stamp out the fires puts us back to where we were in the first place. Taking action on the basis of results without theory of knowledge, without theory of variation, without knowledge about a system. Anything goes wrong, do something about it, overreacting; acting without knowledge, the effect is to make things worse. With the best of intentions and best efforts, managing by results is, in effect, exactly the same, as Dr. Myron Tribus put it, while driving your automobile, keeping your eye on the rear view mirror, what would happen? And that's what management by results is, keeping your eye on results.
W. Edwards Deming
Nothing mankind had done in its short and bloody history had made the slightest bit of difference to this patient geographical realignment.
Meanwhile the Earth, left to its own devices, had deployed a variety of healing mechanisms, physical, chemical, biological, and geological, to recover from the devastating interventions of its human inhabitants. Air pollutants had been broken up by sunlight and dispersed. Bog ore had absorbed much metallic waste. Vegetation had recolonized abandoned landscapes, roots breaking up concrete and asphalt, overgrowing ditches and canals. Erosion by wind and water had caused the final collapse of the last structures, washing it all into sand.
Meanwhile the relentless processes of variation and selection had worked to fill an empty world.
Stephen Baxter
The regime's response to [U. N. ] Security Council Resolution 1696 was predictable, as it was simply a variation of double talk-a tactic they have now mastered to an art form. What does the regime's offer to "seriously talk" really mean? Will it seriously discuss its violations of human rights at home? Will it seriously discuss its patronage of regional militancy? I think not. [This] is a race against time. Will it get the bomb first, thereby bullying the world into appeasement, or will there be an actual convergence of domestic and international pressures [on the regime]?
Reza Pahlavi
If assets are priced rationally, variables that are related to average returns, such as size and book-to-market equity, must proxy for sensitivity to common (shared and thus undiversifiable) risk factors in returns. The time-series regressions give direct evidence on this issue. In particular, the slopes and R2 values show whether mimicking portfolios for risk factors related to size and [book-to-market] capture shared variation in stock and bond returns not explained by other factors.
Eugene Fama
The command of the North River is an object of such importance, that the force and supplies necessary for this purpose must be had at all events. The force requisite for these garrisons, I suppose, has been very judiciously calculated by General Duportail; and I imagine there cannot be any great variation from his report.
Nathanael Greene
... I have no reason to doubt that the universe is the billions of years old that physicists say it is. Further, I find the idea of common descent (that all organisms share a common ancestor) fairly convincing, and have no reason to doubt it. ... I think that evolutionary biologists have contributed enormously to our understanding of the world. Although Darwin's mechanism - natural selection working on variation - might explain many things, however, I do not believe it explains molecular life.
