did it look to its own disease, seeking medicine in piety; but presuming on a false health, it gave itself over with vain curiosity to the study of alien things."
These considerations troubled Abélard not at all. He was conscious of a mind of singular acuteness and a tongue of parts, both of which would do whatever he willed. Beneath all the tumultuous talk of Paris, when he first arrived there, lay the great and unsolved problem of Universals and this he promptly made his own, rushing in where others feared to tread. William of Champeaux had rested on a Platonic basis, Abélard assumed that of Aristotle, and the clash began. It is not a lucid subject, but the best abstract may be found in Chapter XIV of Henry Adams' "Mont-Saint-Michel and Chartres" while this and the two succeeding chapters give the most luminous and vivacious account of the principles at issue in this most vital of intellectual feuds.
"According to the latest authorities, the doctrine of universals which convulsed the schools of the twelfth century has never received an adequate answer. What is a species: what is a genus or a family or an order? More or less convenient terms of classification, about which the twelfth century cared very little, while it cared deeply about the essence of classes! Science has become too complex to affirm the existence of universal truths, but it strives for nothing else, and disputes the problem, within its own limits, almost as earnestly as in the twelfth century, when the whole field of human and superhuman activity was shut between these barriers of substance, universals, and particulars. Little has changed except the vocabulary and the method. The schools knew that their society hung for life on the demonstration that God, the ultimate universal, was a reality, out of which all other universal truths or realities sprang. Truth was a real thing, outside of human experience. The schools of Paris talked and thought of nothing else. John of Salisbury, who attended Abélard's lectures about 1136, and became Bishop of Chartres in 1176, seems to have been more surprised than we need be at the intensity of the emotion. 'One never gets away from this question,' he said. 'From whatever point a discussion starts, it is always led back and attached to that. It is the madness of Rufus about Naevia; "He thinks of nothing else; talks of nothing else, and if Naevia did not exist, Rufus would be dumb."'
... "In these scholastic tournaments the two champions started from opposite points:--one from the ultimate substance, God,--the universal, the ideal, the type;--the other from the individual, Socrates, the concrete, the observed fact of experience, the object of sensual perception. The first champion--William in this instance-- assumed that the universal was a real thing; and for that reason he was called a realist. His opponent--Abélard--held that the universal was only nominally real; and on that account he was called a nominalist. Truth, virtue, humanity, exist as units and realities, said William. Truth, replied Abélard, is only the sum of all possible facts that are true, as humanity is the sum of all actual human beings. The ideal bed is a form, made by God, said Plato. The ideal bed is a name, imagined by ourselves, said Aristotle. 'I start from the universe,' said William. 'I start from the atom,' said Abélard; and, once having started, they necessarily came into collision at some point between the two."
