In 11th-century Egypt, Aristotle's ancient thought that visible objects and our own eyes emit rays of light to enable our vision still held...

Dear Dr,
I am sure that Superman, role model to the Christian Youth of America, only used his X-Ray Vision Feature when absolutely necessary and only against the Forces of Evil.

I hope your interest in X-Ray Vision, Superman, and Aristotle has no prurient aspects. May I recommend St. Thomas Aquinas as an "antidote?"
