G.R. Evans comments at some length on how, for Anselm, divine thinking is a kind of divine speaking:
Anselm introduces [in Monologion 10] the idea of ‘talking’ (locutio). In succeeding chapters we often find thinking and and speaking apparently being used interchangeably… One passage in particular, in Monologion 63, suggests a close association in Anselm’s mind between talking and thinking… ‘For when the Supreme Spirit “speaks” in this way, it is the same same as when he perceives by thought, just as the “speaking” of our own minds is nothing but the act of reviewing our thinking.’… Here, it seems, thinking is envisaged as something more than a still activity, in which we simly contemplate the object of thought; and locutio, too, involves some sort of movement, a reviewing of thought, a process perhaps of bringing it into focus. The exact sense is by no means clear, but there can be no doubt about the clsoeness of association between the two in Anselm’s mind. When God expresses himself by speaking his thought, he creates: ‘So that I may consider, if I can, his speaking, through which all things were made’ (ut de eius locutione, per quam facta sunt omnia); ‘There is one Word, throug hwhich all things were made’ (est unum verbum, per quod facta sunt omnia). It is plain enough, then, that thinking and talking are closely allied activities for Anselm and almost always when he mentions either activity in the Monologion, he considers both their human and their divine application. What he has to say about ‘thinking’ about God will tell us a good deal about his view of the problem of ‘talking’ about God… (Evans, Anselm on Talking About God, 23-4)
