Summa contra Gentiles1.64 Chapter LXIV. Order of the things to be said about the divine knowledge

In order to refute this error, and moreover to show the perfection of the divine knowledge, we must carefully seek the truth about each of the aforesaid arguments, so as to disprove whatever is contrary to the truth. In the first place, then, we shall show that the divine intellect knows singulars; secondly, that it knows things that actually are not; thirdly, that it knows future contingencies with an unerring knowledge; fourthly, that it knows the movements of the will; fifthly that it knows infinite things; sixthly, that it knows all the most trivial and petty things; seventhly, that it knows all evils and privations or defects.
