St. Thomas claims truth is essentially a relation to intellect, and so one account of truth must develop along the lines of what essentially relates to our own intellect. Developed in this way, truth is how Kant describes it in his Copernican turn, namely that the only objects that we can know are those that owe their existence to our thought. So is this the only way to develop St. Thomas’s account of truth?
From one point of view, yes. We know object, but to be an object is to owe ones existence to a mind. It’s not as if there would be cognitive objects without minds to know them. Again, as the scholastics insisted, things are in knowers according to the way the knower exists.
One can distinguish his way out of this problem, but that is not the point here. Our present tendency to identify knowledge with the dialectics of “science” gets its clearest defense in this Scholasticism filtered through Kant, and if we wanted to get to the root of it, we should look here.
