In the modern condition - aiming at Final Participation - most Men realise that truth is something chosen. Truth is no longer compelled upon us from outside; truth active and us passive.
Our modern truth can only be active - if we are not active, there will be no truth.
What is not realised, or denied, is that there is only one reality.
So the situation really-is that there is only one reality, and we must choose it.
The modern sin of pride is manifested in assuming that because we must choose truth, therefore we can invent truth. And because modern truth is invented, then we can deny truth.
