Evolution Social and Organic

by Arthur M. Lewis

Plato we shall pass by; his metaphysical doctrine of ideas contributed little of value to the solution of the riddle of the universe.

We now come to the great Stagirite, Aristotle, founder of the experimental school and father of natural history. Born in 384 B. C., he entered the Academy under Plato when a boy of eighteen. When he was thirty-six Plato died, and Aristotle then left Athens. At forty-one he became the teacher of Alexander the Great. He was the greatest of all the Greeks, and his studies took a wider range than had been embraced by any previous thinker.

Stageira, where he spent his boyhood, was on the Strynomid gulf, and here he observed the variations and gradations between marine plants and animals. It is an evidence of his keen insight that he classified the sponge as an animal. Compare this with Agassiz, the opponent of Darwinism, who, in the 19th century, declared the sponge to be a vegetable.

Aristotle insisted on observation and experience as the foundation of knowledge. “We must not accept a general principle from logic only, but must prove its application to each fact. For it is in facts we must seek general principles, and these must always accord with facts.” He repudiated the idea of purpose in nature, saying, “Jupiter rains not that corn may be increased, but from necessity.” He came very near Von Mohl’s protoplasm when he said, “Germs should have been first produced, and not immediately animals; and that soft mass which first subsisted was the germ.”

Passing over the much misrepresented Epicurus we come two centuries later to the illustrious Roman poet philosopher, Lucretius. In this last century preceeding the Christian era, Greece had fallen from her high estate and become a Roman province. But while Rome had annexed Greece, Greek learning had conquered the Roman mind.

Lucretius in his poem, “The System of Nature,” expounds, with great force, the atomic theory of his Greek forerunners. The first anthropologist, he comes so near to Spencer and Tylor that his ideas, and sometimes even his sentences smack of the 19th century. “The past history of man” he asserts, “lies in no heroic or golden age, but in one struggle out of savagery.” Of the origin of language he says, “Nature impelled them to utter the various sounds of the tongue, and use struck out the names of things.” Of the early struggles of primitive men he says, “Man’s first arms were hands, nails and teeth and stones and boughs broken off from the forests, and flame and fire, as soon as they had become known. Afterward the force of iron and copper was discovered, and the use of copper was known before that of iron, as its nature is easier to work, and it is found in greater quantity. With copper they would labor the soil of the earth and stir up the billows of war. Then by slow steps the sword of iron gained ground and the make of the copper sickle became a byword.” The name of Lucretius closes the long line of the evolutionary pioneers of the ancient world. There the golden vein ceases so far as thinking is concerned, not to reappear until many centuries have passed.

With the decline and fall of the Roman empire, and the rise to power of Christianity, learning was driven from Europe and found refuge among the Arabians. This brings us to the dark or middle ages. It is in the interpretation of the phenomena of this period, that bourgeois free thinkers like Clodd and Draper break down. They tacitly assume that in Europe evolution was suspended for over a thousand years; and all because of the Christian church. They fail to recognize that deeper cause, the medieval form of wealth production, which gave the church its power to repress learning in the interest of the lords of the land, among which the church herself was greatest; owning as she did one-third of the soil of Europe.

The bourgeois radical cannot perceive that during this period social processes were being gradually transformed and that an economic foundation was being laid that would make possible the renaissance and put science in an impregnable position, and make the progressive acceptance of evolution inevitable. Engels says: “The Middle Ages were reckoned as a mere interruption of history by a thousand years of barbarism. The great advances of the Middle Ages—the broadening of European learning, the bringing into existence of great nations, which arose, one after the other, and finally the enormous technical advances of the fourteenth and fifteenth centuries—all this no one saw”.

But it cannot be denied that this was a terrible period for any thinker who had the misfortune to be born in it. All that was great and noble in the thought of Greece and Rome was rigorously suppressed. The “perfecting principle” of Aristotle was wrested to theological uses. An emaciated form of his philosophy, and a literal interpretation of the scriptures, constituted the only permissible studies. Outside this dilution of Aristotle, the only thing in Greek thought which appealed to the medieval mind was the Pythagorean mystical use of numbers. The conclusions reached by that method were truly remarkable, especially when we remember that they engaged such notable men as Augustine, the celebrated Bishop of Hippo.

These are examples: Because there are three persons in the trinity, Father, Son, and Holy Ghost, three orders in the church, bishops priests and deacons; three degrees of attainment, light, purity and knowledge; three virtues, faith, hope and charity, and three eyes in a honeybee; therefore, there can only be three colors, red, yellow and blue. Because there were seven churches in the apocalypse, seven golden candlesticks, seven cardinal virtues, seven deadly sins and seven sacraments; therefore, there could only be seven planets and seven metals. Because there were seventy-two disciples and seventy-two interpreters of the old testament and seventy-two mystical names of God; therefore there must be no more and no less than seventy-two joints in the human body.
