Loosing touch with reality is the very essence of madness. Quite the contrary, such a person will likely boast in his empirical scrupulousness. He will insist that a sober assessment of the evidence shows there is no Truth, there is no God, there are no moral absolutes. But such protestations are hollow. He is like the hunter who stomps boisterously into the woods and then emerges a short time later confidently to proclaim the woods devoid of game.
Truth hides from the arrogant and the distrustful.
At the heart of our society's rejection of Truth is its aversion to moral absolutes. The natural consequences of violating God's moral laws are just as certain as the consequences of ignoring natural laws. We can deny the existence of gravity, but if we step off a cliff we will still fall. If we ignore the moral absolutes God has built into the cosmos, we will suffer. You would expect such suffering to awaken us to our delinquency, but typically it does not.
