One distinction between the evolution of animals and that of patterns must not be lost sight of: in the former the survival of the fittest appears to be mainly due to an elimination of the un-fittest, whereas in the latter there is a certain amount of conscious selection.

A further argument against this view may be urged from the standpoint that however unconscious the evolution of the lower animals may be, the case is very different with man. He is conscious and self-conscious, and he can direct his own evolution. In the first place, “Can he do so?” and in the second, “Has he done so?” First let us see what has happened.

I suppose it is one of the best established teachings of history that the evolution of a nation has not been consciously directed by the individuals which compose it. A few men may have sought to guide the course of politics or to adjust its foreign policy; but their efforts are futile unless supported by the people themselves, and the luxuriousness of living of the majority, the laxity of their morals, or some other irresponsible factor, may entirely wreck individual effort. Nations as a whole have blindly worked out their own salvation or ruin in just the same way as a group of animals living in geological times may have survived to the present day or may have become extinct.

The essential conservatism of the human mind is a fact of prime importance. Savages, children, and the less intelligent of the civilised races are similar in this respect. This has long been recognised, and that “there is no new thing under the sun” is an oft-repeated, widely-recognised truism. In proportion as change is rare, so progress is slow. It is only the happy coincidence of certain combinations which acts as a stimulant to variation, but this appears to have an increasing tendency to occur. The more savage the race the more conservative it is as a rule.

Just as the tendency to variability is of necessity a steadily increasing factor in the evolution of animals, so it is in man, and proportionately more so as he is raised above the level of the brute. Increase of complexity leads to that instability which is the mother of variability.

The above-mentioned statements are merely expressions of facts known to all. It will probably be admitted that among less civilised peoples their evolution may have been undirected by themselves; but with increased complexity comes augmented mental power, and it may be urged that this may, so to speak, take the helm; but I would venture to ask, Is there much evidence in support of this view? The mind of man is subject, like his body, to the ordinary operations of the universe, his individuality is apparent rather than real, and just as one may move to and fro on the face of the earth yet at the same time the traveller and the bed-ridden person are revolving round the axis of the earth at the same rate, and are equally trundling with the globe through space, so, too, mind cannot escape from the forces which act on the body.

It is believed by some that there were periods in the history of organisms when evolution took place more rapidly than at other times; perhaps this was due to variability occurring more extensively, which again may have been partly due to changes in the environment. There is no reason to believe that variation (which is the material that makes evolution possible) occurs uniformly. There is no need to touch further upon these yet unsolved problems of Biology; at all events we find that in decorative art evolution has been spasmodic or discontinuous, that there are periods of quiescence and of activity. I have already suggested that the isolation of a people and uniformity in their existence will tend to stagnation in art, and that intercourse with other peoples, whether by trade, war or migration, serves as a stimulus to artistic expression.

To return to our more immediate subject, consciousness of purpose has extremely little to do with human evolution, nor has it much more to say to the evolution of patterns among primitive peoples.

The selection of one design instead of another, or of a particular part of a design, is a conscious act, but probably in the great majority of cases an unreasoning one. And the selection is limited to that individual object. It is inconceivable that a savage should copy or adapt a certain design because it promises to develop into a more pleasing pattern. While there is a certain amount of conscious selection, the variation as a whole of any design is an entirely unguided operation so far as the intelligence of the human units is concerned.
