History of Western Philosophy - Bertrand Russell [238]
Clearly an argument with such a distinguished history is to be treated with respect, whether valid or not. The real question is: Is there anything we can think of which, by the mere fact that we can think of it, is shown to exist outside our thought? Every philosopher would like to say yes, because a philosopher's job is to find out things about the world by thinking rather than observing. If yes is the right answer, there is a bridge from pure thought to things, if not, not. In this generalized form, Plato uses a kind of ontological argument to prove the objective reality of ideas. But no one before Anselm had stated the argument in its naked logical purity. In gaining purity, it loses plausibility; but this also is to Anselm's credit.
For the rest, Anselm's philosophy is mainly derived from St Augustine, from whom it acquires many Platonic elements. He believes in Platonic ideas, from which he derives another proof of the existence of God. By Neoplatonic arguments he professes to prove not only God, but the Trinity. (It will be remembered that Plotinus has a Trinity, though not one that a Christian can accept as orthodox.) Anselm considers reason subordinate to faith. 'I believe in order to understand,' he says; following Augustine, he holds that without belief it is impossible to understand. God, he says, is not just, but justice. It will be remembered that John the Scot says similar things. The common origin is in Plato.
St Anselm, like his predecessors in Christian philosophy, is in the Platonic rather than the Aristotelian tradition. For this reason, he has not the distinctive characteristics of the philosophy which is called 'scholastic', which culminated in Thomas Aquinas. This kind of philosophy may be reckoned as beginning with Roscelin, who was Anselm's contemporary, being seventeen years younger than Anselm. Roscelin marks a new beginning, and will be considered in a later chapter.
When it is said that medieval philosophy, until the thirteenth century, was mainly Platonic, it must be remembered that Plato, except for a fragment of the Timaeus, was known only at second or third hand. John the Scot, for example, could not have held the views which he did hold but for Plato, but most of what is Platonic in him comes from the pseudo-Dionysius. The date of this author is uncertain, but it seems probable that he was a disciple of Proclus the Neoplatonist. It is probable, also, that John the Scot had never heard of Proclus or read a line of Plotinus. Apart from the pseudo-Dionysius, the other source of Platonism in the Middle Ages was Boethius. This Platonism was in many ways different from that which a modern student derives from Plato's own writings. It omitted almost everything that had no obvious bearing on religion, and in religious philosophy it enlarged and emphasized certain aspects at the expense of others. This change in the conception of Plato had already been effected by Plotinus. The knowledge of Aristotle was also fragmentary, but in an opposite direction: all that was known of him until the twelfth century was Boethius's translation of the Categories and De Emendatione. Thus Aristotle was conceived as a mere dialectician, and Plato as only a religious philosopher and the author of the theory of ideas. During the course of the later Middle Ages, both these partial conceptions were gradually emended, especially the conception of Aristotle. But the process, as regards Plato, was not completed until the Renaissance.
