which were seen were known and there were other things which were

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

a family or an order? More or less convenient terms of classification,
