Kenneth R. Miller on Fossils

Go

The fact of the matter is that the fossil record not only documents evolution, but that it was the fossil record itself which forced natural scientists to abandon their idea of the fixity of species and look instead for a plausible mechanism of change, a mechanism of evolution. The fossil record not only demonstrates evolution in extravagant detail, but it dashes all claims of the scientific creationists concerning the origin of living organisms.

Daniel Dennet on the Illusion of Uncaused Acts

Go

Whatever else we are, we are information-processing systems, and all information-processing systems rely on amplifiers of a sort. Relatively small causes are made to yield relatively large effects. … Vast amounts of information arrive on the coattails of negligible amounts of energy, and then, thanks to the amplification powers of systems of switches, the information begins to do some work — evoking other information that was stored long ago, for instance transmuting it for the present occasion in a million small ways, and leading eventually to an action whose pedigree of efficient (or triggering) causation is so hopelessly inscrutable as to be invisible. We see the dramatic effects leaving; we don’t see the causes entering; we are tempted by the hypothesis that there are no causes.

Stephen Jay Gould on Fact and Theory

Go

Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world’s data. Theories are structures of ideas that explain and interpret facts. Facts don’t go away when scientists debate rival theories to explain them. Einstein’s theory of gravitation replaced Newton’s in this century, but apples didn’t suspend themselves in midair, pending the outcome. And humans evolved from ape-like ancestors whether they did so by Darwin’s proposed mechanism or by some other yet to be discovered.

Alasdair MacIntyre on Social Ethics or None at All

Go A moral philosophy ... characteristically presupposes a sociology. For every moral philosophy offers explicitly or implicitly at least a partial conceptual analysis of the relationship of an agent to his or her reasons, motives, intentions and actions, and in so doing generally presupposes some claim that these concepts are embodied or at least can be in the real social world. Even Kant, who sometimes seems to restrict moral agency to the inner realm of the noumenal, implies otherwise in his writings on law, history and politics. Thus it would generally be a decisive refutation of a moral philosophy to show that moral agency on its own account of the matter could never be socially embodied; and it also follows that we have not yet fully understood the claims of any moral philosophy until we have spelled out what its social embodiment would be.

Stephen Jay Gould on Punctuated Equilibria

Go

Since we proposed punctuated equilibria to explain trends, it is infuriating to be quoted again and again by creationists — whether through design or stupidity, I do not know — as admitting that the fossil record includes no transitional forms. The punctuations occur at the level of species; directional trends (on the staircase model) are rife at the higher level of transitions within major groups.

Aloysius Martinich on Informal Logical Fallacies

Go

Fallacies seem to resist an illuminating and perspicuous categorization and characterization. There is a quite banal consideration that makes the search for an adequate taxonomy seem doomed to failure. While there are a few principles of correct reasoning, the number of incorrect patterns of reasoning are unlimited. In other words, there is no underestimating the ability of human beings to invent new ways of making mistakes. The seems to be the view of H.W.B Joseph, who is quoted as saying, “Truth may have its norms, but error is infinite in its aberrations and they cannot be digested in any classification”.

I.L. Cohen on Mutation and Probability

Go

To propose and argue that mutations even in tandem with ‘natural selection’ are the root-causes for 6,000,000 viable, enormously complex species, is to mock logic, deny the weight of evidence, and reject the fundamentals of mathematical probability.

Stephen Jay Gould on Creationism

Go

In candid moments, leading creationists will admit that the miraculous character of origin and destruction precludes a scientific understanding. Morris writes (and Judge Overton quotes): ‘God was there when it happened. We were not there… Therefore, we are completely limited to what God has seen fit to tell us, and this information is in His written Word.’

Ernst Mayr on Mutation

Go

The occurrence of genetic monstrosities by mutation … is well substantiated, but they are such evident freaks that these monsters can be designated only as ‘hopeless.’ They are so utterly unbalanced that they would not have the slightest chance of escaping elimination through stabilizing selection …. the more drastically a mutation affects the phenotype, the more likely it is to reduce fitness. To believe that such a drastic mutation would produce a viable new type,
capable of occupying a new adaptive zone, is equivalent to believing in miracles …. The finding of a suitable mate for the ‘hopeless monster’ and the establishment of reproductive isolation from the normal members of the parental population seem to me insurmountable difficulties.
