The humble scientist

I've had the book St Thomas Aquinas, by G K Chesterton, on my shelves for many years, but had never read it until this week. What a great book, very readable, very clear and able to give insight not only into Aquinas but also into his time and into the history of philosophy in general. Over the next few days I'll be adding various long and short extracts from the book to this blog. 

We have all heard of the humility of the man of science; of many who were very genuinely humble; and of some who were very proud of their humility. It will be the somewhat too recurrent burden of this brief study that Thomas Aquinas really did have the humility of the man of science; as a special variant of the humility of the saint. It is true that he did not himself contribute anything concrete in the experiment or detail of physical science; in this, it may be said, he even lagged behind the last generation, and was far less of an experimental scientist than his tutor Albertus Magnus. But for all that, he was historically a great friend to the freedom of science. The principles he laid down, properly understood, are perhaps the best that can be produced for protecting science from mere obscurantist persecution. For instance, in the matter of the inspiration of Scripture, he fixed first on the obvious fact, which was forgotten by four furious centuries of sectarian battle, that the meaning of Scripture is very far from self-evident and that we must often interpret it in the light of other truths. If a literal interpretation is really and flatly contradicted by an obvious fact, why then we can only say that the literal interpretation must be a false interpretation. But the fact must really be an obvious fact. And unfortunately, nineteenth century scientists were just as ready to jump to the conclusion that any guess about nature was an obvious fact, as were seventeenth-century sectarians to jump to the conclusion that any guess about Scripture was the obvious explanation. Thus, private theories about what the Bible ought to mean, and premature theories about what the world ought to mean, have met in loud and widely advertised controversy, especially in the Victorian time; and this clumsy collision of two very impatient forms of ignorance was known as the quarrel of Science and Religion.
But St. Thomas had the scientific humility in this very vivid and special sense; that he was ready to take the lowest place; for the examination of the lowest things. He did not, like a modern specialist, study the worm as if it were the world; but he was willing to begin to study the reality of the world in the reality of the worm. His Aristotelianism simply meant that the study of the humblest fact will lead to the study of the highest truth. That for him the process was logical and not biological, was concerned with philosophy rather than science, does not alter the essential idea that he believed in beginning at the bottom of the ladder. But he also gave, by his view of Scripture and Science, and other questions, a sort of charter for pioneers more purely practical than himself. He practically said that if they could really prove their practical discoveries, the traditional interpretation of Scripture must give way before those discoveries. He could hardly, as the common phrase goes, say fairer than that. If the matter had been left to him, and men like him, there never would have been any quarrel between Science and Religion. He did his very best to map out two provinces for them, and to trace a just frontier between them.
It is often cheerfully remarked that Christianity has failed, by which is meant that it has never had that sweeping, imperial and imposed supremacy, which has belonged to each of the great revolutions, every one of which has subsequently failed. There was never a moment when men could say that every man was a Christian; as they might say for several months that every man was a Royalist or a Republican or a Communist. But if sane historians want to understand the sense in which the Christian character has succeeded, they could not find a better case than the massive moral pressure of a man like St. Thomas, in support of the buried rationalism of the heathens, which had as yet only been dug up for the amusement of the heretics. It was, quite strictly and exactly, because a new kind of man was conducting rational enquiry in a new kind of way, that men forgot the curse that had fallen on the temples of the dead demons and the palaces of the dead despots; forgot even the new fury out of Arabia against which they were fighting for their lives; because the man who was asking them to return to sense, or to return to their senses, was not a sophist but a saint. Aristotle had described the magnanimous man, who is great and knows that he is great. But Aristotle would never have recovered his own greatness, but for the miracle that created the more magnanimous man; who is great and knows that he is small.
