because it's true. (synchronic possibility in Aquinas)

The more I read, the more I find myself at odds with Aquinas on a myriad of issues. And then he says this:

The divine will is capable of opposites, not in the sense that it first wills something and afterwards does not (which would be repugnant to its immutability), nor in the sense that it can will good and evil (for that would put defectibility in God), but rather in the sense that it can will or not will this particular thing.
