Seeing Is Believing

Galileo.

Leonardo: if the beard fits, wear it.

     "It's through seeing that you understand the beauty of created things, the greatest of the things that induce love."
     - Leonardo arguing in the early 1500s for what is in front of us, what we can see, touch, smell, hear, taste.    

     Galileo, one hundred years later, complained that "people were denying the evidence of their own senses and submitting to the judgement of others [i.e. the church], allowing people totally ignorant of an art or science to be judges of intellectuals ... these are the new powers that can ruin republics and subvert states."
     Same old refrain, 500 years later.
