Christianity has done something which is totally revolutionary. Christ did not say “I have the truth”, he said “I am the truth”, Moses did not say so, Buddha did not say so, Mohammed did not say so. Christ alone claims that He is The Truth, capital T. Now, the very moment that you are confronted with the Truth, and you suddenly discover all the lies that are in us, there are two possibilities. Either you kneel down and adore and recognise Christ to be God, or you run away and say “depart from us, we can do without you”.
--Alice von Hildebrand, “The Secular War on the Supernatural.”
How does a materialist account for the stubborn fact of consciousness? If it’s nothing but physical brain activity, then what is my consciousness of my physical brain activity? Remember, the knowledge of a thing one of the parts of the thing known. This can be proved by formal logic alone. For the alternative would make accurate knowledge (knowledge that matches the thing known) impossible. For in the very act of knowing all the facts about a thing you create a new fact about that thing: that it was known. And that fact can be only known still by another act of knowing, et cetera ad infinitum.
