In the first two chapters of the Monologion Anselm shows, or tries to show that “Of all the things that exist, there is one that is the best, greatest and supreme.” In this paper I examine his argument.

In the opening chapter of the Monologion, Anselm offers an intriguing proof for the existence of a Platonic form of goodness. This proof is extremely interesting, both in itself and for its place in the broader argument for God’s existence that Anselm develops in the Monologion as a whole. Even so, it has yet to receive the scholarly attention that it deserves. My aim in this article is to begin correcting this state of affairs by examining Anslem’s proof (...) in some detail. In particular, I aim to clarify the proof’s structure, motivate and explain its central premises, and begin the larger project of evaluating its overall success as an argument for Platonism about goodness.

The article analyzes the a posteriori argumentation for the existence of God present in saint Anselm’s Monologion. It defends that the arguments in chapters I-IV are parts of a single argumentative way comparable with the fourth way of Thomas Aquinas. The only starting point for the argumentation is the evidence of the degrees of transcendental perfection (goodness and greatness) found in things. According to this single point of departure, the argument also has a single formulation of the principle of (...) causality given in chapter I. By this principle, Anselm infers the existence of a single first principle (that which is through itself) from its effects (that which is through another). Contrary to what is usually held, it is shown that chapters III and IV do not contain arguments properly meant to demonstrate God’s existence. Chapter III’s specific goal is to demonstrate the impossibility that that which is through itself may be something multiple, while chapter IV aims to demonstrate the impossibility that the supreme nature through whom all things exist may be overcome or equaled in dignity by another. Both arguments depend of the principle of causality formulated in chapter I to be conclusive. (shrink)
