Creationists argue that natural selection is only a negative process, and therefore cannot create anything. Chopra argues that skepticism is only a negative process, and therefore does not lead to knowledge. Both are wrong for the same reasons. They ignore the generation of diversity and new ideas upon which natural selection and skepticism acts. Weeding out the unfit is critical to both - natural selection allows evolution to proceed, and skepticism allows science to advance.
Group selection and individual selection are just two of the selection processes that have played important roles in evolution. There also is selection within individual organisms (intragenomic conflict), and selection among multi-species communities (an idea that now is getting attention in work on the human microbiome). All four of these levels of selection find a place in multi-level selection theory.
Objectivity is impossible and it is also undesirable. That is, if it were possible it would be undesirable, because if you have any kind of a social aim, if you think history should serve society in some way; should serve the progress of the human race; should serve justice in some way, then it requires that you make your selection on the basis of what you think will advance causes of humanity.
You can be a thorough-going Neo-Darwinian without imagination, metaphysics, poetry, conscience, or decency. For 'Natural Selection' has no moral significance: it deals with that part of evolution which has no purpose, no intelligence, and might more appropriately be called accidental selection, or better still, Unnatural Selection, since nothing is more unnatural than an accident. If it could be proved that the whole universe had been produced by such Selection, only fools and rascals could bear to live.
I would rather do a good hours work weeding than write two pages of my best; nothing is so interesting as weeding. I went crazy over the outdoor work, and at last had to confine myself to the house, or literature must have gone by the board.
Artificial selection turned the wolf into the shepherd, and the wild grasses into wheat and corn. In fact, almost every plant and animal that we eat today was bred from a wild, less edible ancestor. If artificial selection can work such profound changes in only ten or fifteen thousand years, what can natural selection do operating over billions of years? The answer is all the beauty and diversity of life.
No gain in keeping, no loss in weeding out.
I suppose I have very undesirable traits. I am very critical, which is very undesirable. But it is good from a business point of view.
Time has a wonderful way of weeding out the trivial.
Natural selection may lead to benefits for species, but these `higher' advantages can only arise as sequelae, or side consequences, of natural selection's causal mechanism: differential reproductive success of individuals.
The essence of Darwinism lies in its claim that natural selection creates the fit. Variation is ubiquitous and random in direction. It supplies raw material only. Natural selection directs the course of evolutionary change.
We need only take our heads out of the sand to see clearly that interventionism not only has failed to provide the promised something-for-nothing, but has led to all sorts of undesirable consequences. Indeed, many are just beginning to realize that we are moving towards disaster even though we have been on a wrong heading for decades.
If your aims as a donor are modest, you can accomplish an awful lot. When your aims become elevated beyond a reasonable level, you not only don't accomplish much, but you can cause a great deal of damage.
Birth control is nothing more or less than...weeding out the unfit.
What campaigns are for is weeding out the people who, for one way or another, weren't making it for the long haul.
Natural selection is a blind and undirected consequence of the interaction between variation and the environment. Natural selection exists only in the continuous present of the natural world: it has no memory of its previous actions, no plans for the future, or underlying purpose.
