Without knowledge we descend into darkness. Back to our animal origins. We become imitators. Memorizers. Pretenders of the illusion of the civilized. Most of us don't know really how civilization came to be. How mankind rose from its primal origins. We don't know really the history of anything. So we look around and adapt to looking and acting like civilized, intelligent beings. But if you compare any real definition of intelligence to what is around, we see that there is a total mismatch.
The real questions elude us and we find easier ones with simple answers. We brush away our anxieties and quickly turn away to find some fun somewhere somehow to forget and to continue.
