Plantinga's paper on being an anti-realist

This is the link to Plantinga's How to Be an Anti-Realist.

So what we really have here is a sort of antinomy. On the one hand there is a deep impulse towards anti-realism; there can't really be truths independent of noetic activity. On the other hand there is the disquieting fact that anti-realism, at least of the sorts we have been considering, seems incoherent and otherwise objectionable. We have here a paradox seeking resolution, a thesis and antithesis seeking synthesis. And what is by my lights the correct synthesis, was suggested long before Hegel. This synthesis was suggested by Augustine, endorsed by most of the theistic tradition, and given succinct statement by Thomas Aquinas: "Even if there were no human intellects, there could be truths because of their relation to the divine intellect. But if, per impossible, there were no intellects at all, but things continued to exist, then there would be no such reality as truth." (De Veritate Q. 1, A.6 Respondeo). The thesis, then, is that truth cannot be independent of noetic activity on the part of persons. The antithesis is that it must be independent of our noetic activity. And the synthesis is that truth is independent of our intellectual activity but not of God's.

And later:

By way of conclusion then: the fundamental anti-realist intuitionthat truth is not independent of mind-is indeed correct. This intuition is best accommodated by the theistic claim that necessarily, propositions have two properties essentially: being conceived by God and being true if and only if believed by God. So how can we sensibly be antirealists? Easily enough: by being theists.
