As I mentioned above, in speaking to a modern audience, it is essential to address the notion of objective truth. Yes, it exists. Yes, we can be certain of it. And yes, we can logically refute any attack against it. Peter Kreeft addresses the issue of objective truth magnificently in a chapter of his great book, Handbook of Christian Apologetics, a book that is essential for any Catholic/Christian library.

...it is essential to address the notion of objective truth. Yes, it exists. Yes, we can be certain of it. And yes, we can logically refute any attack against it.

Putting aside the question of what you mean by "objective truth," I notice that you left out:

And yes, we can know with certainty whether or not any particular proposition is an objective truth.

Knowing that objective truth exists as an ontological category is different than knowing what is contained within that category, no?
