Monologion

BUT, just as it has been proved that there is a being that is supremely good, since all goods are good through a single being, which is good through itself; so it is necessarily inferred that there is something supremely great, which is great through itself. But, I do not mean physically great, as a material object is great, but that which, the greater it is, is the better or the more worthy,--wisdom, for instance. And since there can be nothing supremely great except what is supremely good, there must be a being that is greatest and best, i. e., the highest of all existing beings.
