That's called coping. Coping with life, just getting by, being thankful that we can figure out how things work and just make do. The other category, he says, is radically different. We create the way we experience life. The wise man builds his house on the solid rock of truth, and not on the shifting sands of instability.
Reality is that which is real and enduring.
The foolish man, living only in sense perception, has no measure for reality and builds his life on false options and erroneous concepts and the storms of experience tear the walls apart. Truth alone endures to the eternal day. I had a professor in the seminary who was a member of the Jesus Seminar, which is a group of theologians and teachers in seminaries in major universities. A hundred of them have gotten together to take a new look and come to a new viewpoint about the life of the historical Jesus. They are shifting from the belief that Jesus was an apocalyptical preacher telling us about how the world would end and how there would be divine intervention at the last moment.
