Freeman Dyson Quotes

Natural selection will not remove ignorance from future generations.

Species go extinct because there are historical contraints built into a given body or a given design.

They say, you know, about evolution, it surely happened because their fossil record shows that. Look, my body and your body are miracles of design. Scientists are pretending they have the answer as how we got this way when natural selection couldn't possibly have produced such machines.

Most species do their own evolving, making it up as they go along, which is the way Nature intended.

It's the old idea that the process of evolution is some push in the direction of greater complexity--in particular greater intellectual complexity. In one twig of the tree of life, namely ours, having a big brain happened to have advantages. But that's just what worked for a particular species of primate 5 to 7 million years ago.

Most species do their own evolving, making it up as they go along, which is the way Nature intended. And this is all very natural and organic and in tune with mysterious cycles of the cosmos, which believes that there's nothing like millions of years of really frustrating trial and error to give a species moral fiber and, in some cases, backbone.

Species evolve exactly as if they were adapting as best they could to a changing world, and not at all as if they were moving toward a set goal.

Darwinian natural selection only yields adaptation to changing local environments, and better function in an immediate habitat might just as well be achieved by greater simplicity in form and behavior as by ever-increasing complexity.

... if variations useful to any organic being do occur, assuredly individuals thus characterized will have the best chance of being perserved in the struggle for life; and from the strong principle of inheritance they will tend to produce offsping similarly characterized. This principle of preservation, I have called, for the sake of brevity, Natural Selection.

evolution is a tinkerer, an ad-hocker, and a jury-rigger. It works with what it has on hand, not with what it has in mind. Some of its inventions prove elegant, while in others you can see the seams and dried glue.

As some species die out, forms better adapted to utilize the obstacles against which they struggled in vain come into being.

Evolution ... is opportunistic, hence unpredictable.

Biologically, man is still the great amateur of the animal kingdom; he is unique in his lack of anatomical and physiological specialization.

There are any number of things that survive great, and don't need any kind of consciousness, so why bother going through all the trouble of evolving monkeys that don't run very well or climb very fast or have particularly sharp teeth, but have big heads.

Evolution has no long-term goal. There is no long-distance target, no final perfection to serve as a criterion for selection, although human vanity cherishes the absurd notion that our species is the final goal of evolution.

In less than eight years "The Origin of Species" has produced conviction in the minds of a majority of the most eminent living men of science. New facts, new problems, new difficulties as they arise are accepted, solved, or removed by this theory; and its principles are illustrated by the progress and conclusions of every well established branch of human knowledge.

Throughout the past century there has always existed a significant minority of first-rate biologists who have never been able to bring themselves to accept the validity of Darwinian claims. In fact, the number of biologists who have expressed some degree of disillusionment is practically endless.

Organisms [...] are directed and limited by their past. They must remain imperfect in their form and function, and to that extent unpredictable since they are not optimal machines. We cannot know their future with certainty, if only because a myriad of quirky functional shifts lie within the capacity of any feature, however well adapted to a present role.

It was Darwin's chief contribution, not only to Biology but to the whole of natural science, to have brought to light a process by which contingencies a priori improbable, are given, in the process of time, an increasing probability, until it is their non-occurrence rather than their occurrence which becomes highly improbable.

The species and the genus are always the work of nature [i.e. specially created]; the variety mostly that of circumstance; the class and the order are the work of nature and art.

Real life seeks the gentle slopes at the back of Mount Improbable, while creationists are blind to all but the daunting precipice at the front.

His subject is the "Origin of Species," & not the origin of Organization; & it seems a needless mischief to have opened the latter speculation at all.

Species do not grow more perfect: the weaker dominate the strong, again and again- the reason being that they are the great majority, and they are also cleverer. Darwin forgot the mind (-that is English!): the weak possess more mind. ... To acquire mind, one must need mind-one loses it when one no longer needs it.

Evolution is the phenomenon of change and the challenge of the next time cycle will involve the creation of constructs that will provide the kind of dynamic knowledge base that can assist the challenges of tomorrow (involving both fundamental and extended information).

I believe the evidence strongly supports common descent. But the root question remains unanswered: What has caused complex systems to form?
