Scripture tells us that in the end times, people will lose the ability to reason. They will think they are waxing eloquently and intelligently, however their thoughts and actions will lack wisdom.
This is becoming more and more clear everyday, as we spiral toward the end of all known things and come face to face with our Creator.
"Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done." Romans 1:28
