Uniformity Is Easy

When you listen and read one thinker, you become a clone… two thinkers, you become confused… ten thinkers, you’ll begin developing your own voice… two or three hundred thinkers, you become wise and develop your voice.

― Timothy Keller

There is a messiness to gaining wisdom. To get there, you must go through confusion, and when confused people interact it can become quite tumultuous. It's simpler to deny that more than one viewpoint could have validity. Clones are easier to manage than thinkers.
