In his well-known essay "On Various Kinds of Thinking," historian James Harvey Robinson concludes that "our convictions on important matters are not the result of knowledge or critical thought, nor, it may be added, are they often dictated by supposed self-interest. Most of them are pure prejudices in the proper sense of that word." In this essay (also from his book The Mind in the Making, 1921), Robinson examines how the ancient Greeks challenged and overturned the conventional wisdom (or "pure prejudices") of their era.

In our own time, critical thinking has become a fashionable phrase--a buzzword that's "universally accepted but rarely examined," according to Joe Kincheloe. After reading Robinson's essay, try to summarize his definition of critical thinking, and then be prepared to explain why you agree or disagree with his conclusions.

Beginning of Critical Thinking

by James Harvey Robinson

The Egyptians were the first people, so far as we know, who invented a highly artificial method of writing, about five thousand years ago, and began to devise new arts beyond those of their barbarous predecessors. They developed painting and architecture, navigation, and various ingenious industries; they worked in glass and enamels and began the use of copper, and so introduced metal into human affairs. But in spite of their extraordinary advance in practical, matter-of-fact knowledge they remained very primitive in their beliefs. The same may be said of the peoples of Mesopotamia and of the western Asiatic nations in general--just as in our own day the practical arts have got a long start compared with the revision of beliefs in regard to man and the gods.

The peculiar opinions of the Egyptians do not enter directly into our intellectual heritage, but some of the fundamental religious ideas which developed in western Asia have, through the veneration for the Hebrew Scriptures, become part and parcel of our ways of thinking.

To the Greeks, however, we are intellectually under heavy obligation. The literature of the Greeks, in such fragments as escaped destruction, was destined, along with the Hebrew Scriptures, to exercise an incalculable influence in the formation of our modern civilized minds. These two dominating literary heritages originated about the same time--day before yesterday--viewed in the perspective of our race's history. Previous to the Greek civilization books had played no great part in the development, dissemination, and transmission of culture from generation to generation. Now they were to become a cardinal force in advancing and retarding the mind's expansion.

It required about a thousand years for the Greek shepherds from the pastures of the Danube to assimilate the culture of the highly civilized regions in which they first appeared as barbarian destroyers. They accepted the industrial arts of the eastern Mediterranean, adopted the Phoenician alphabet, and emulated the Phoenician merchant. By the seventh century before our era they had towns, colonies, and commerce, with much stimulating running hither and thither. We get our first traces of new intellectual enterprise in the Ionian cities, especially Miletus, and in the Italian colonies of the Greeks. Only later did Athens become the unrivaled center in a marvelous outflowering of the human intelligence.

It is a delicate task to summarize what we owe to the Greeks. Leaving aside their supreme achievements in literature and art, we can consider only very briefly the general scope and nature of their thinking as it relates most closely to our theme.

The chief strength of the Greeks lay in their freedom from hampering intellectual tradition. They had no venerated classics, no holy books, no dead languages to master, no authorities to check their free speculation. As Lord Bacon reminds us, they had no antiquity of knowledge and no knowledge of antiquity. A modern classicist would have been a forlorn outlander in ancient Athens, with no books in a forgotten tongue, no obsolete inflections to impose upon reluctant youth. He would have had to use the everyday speech of the sandal-maker and fuller.

For a long time no technical words were invented to give aloofness and seeming precision to philosophic and scientific discussion. Aristotle was the first to use words incomprehensible to the average citizen. It was in these conditions that the possibilities of human criticism first showed themselves. The primitive notions of man, of the gods, and of the workings of natural forces began to be overhauled on an entirely new scale. Intelligence developed rapidly as exceptionally bold individuals came to have their suspicions of simple, spontaneous, and ancient ways of looking at things. Ultimately there came men who professed to doubt everything.

As Abelard long after put it, "By doubting we come to question, and by seeking we may come upon the truth." But man is by nature credulous. He is victimized by first impressions, from which he can only escape with great difficulty. He resents criticism of accepted and familiar ideas as he resents any unwelcome disturbance of routine. So criticism is against nature, for it conflicts with the smooth workings of our more primitive minds, those of the child and the savage.

It should not be forgotten that the Greek people were no exception in this matter. Anaxagoras and Aristotle were banished for thinking as they did; Euripides was an object of abhorrence to the conservative of his day, and Socrates was actually executed for his godless teachings. The Greek thinkers furnish the first instance of intellectual freedom, of the "self-detachment and self-abnegating vigor of criticism" which is most touchingly illustrated in the honest "know-nothingism" of Socrates. They discovered skepticism in the higher and proper significance of the word, and this was their supreme contribution to human thought.

One of the finest examples of early Greek skepticism was the discovery of Xenophanes that man created the gods in his own image. He looked about him, observed the current conceptions of the gods, compared those of different peoples, and reached the conclusion that the way in which a tribe pictured its gods was not the outcome of any knowledge of how they really looked and whether they had black eyes or blue, but was a reflection of the familiarly human. If the lions had gods they would have the shape of their worshipers.

No more fundamentally shocking revelation was ever made than this, for it shook the very foundations of religious belief. The home life on Olympus as described in Homer was too scandalous to escape the attention of the thoughtful, and no later Christian could have denounced the demoralizing influence of the current religious beliefs in hotter indignation than did Plato. To judge from the reflection of Greek thought which we find in Lucretius and Cicero, none of the primitive religious beliefs escaped mordant criticism.

The second great discovery of the Greek thinkers was metaphysics. They did not have the name, which originated long after in quite an absurd fashion,* but they reveled in the thing. Nowadays metaphysics is revered by some as our noblest effort to reach the highest truth, and scorned by others as the silliest of wild-goose chases. I am inclined to rate it, like smoking, as a highly gratifying indulgence to those who like it, and, as indulgences go, relatively innocent. The Greeks found that the mind could carry on an absorbing game with itself. We all engage in reveries and fantasies of a homely, everyday type, concerned with our desires or resentments, but the fantasy of the metaphysician busies itself with conceptions, abstractions, distinctions, hypotheses, postulates, and logical inferences. Having made certain postulates or hypotheses, he finds new conclusions, which he follows in a seemingly convincing manner. This gives him the delightful emotion of pursuing Truth, something as the simple man pursues a maiden. Only Truth is more elusive than the maiden and may continue to beckon her follower for long years, no matter how gray and doddering he may become.

* When in the time of Cicero the long-hidden works of Aristotle were recovered and put into the hands of Andronicus of Rhodes to edit, he found certain fragments of highly abstruse speculation which he did not know what to do with. So he called them "addenda to the Physics"--Ta meta ta physica. These fragments, under the caption "Metaphysica," became the most revered of Aristotle's productions, his "First Philosophy," as the Scholastics were wont to call it.
