power of the mind

Shakespeare said it first in a line given unto Hamlet "...for there is nothing either good or bad, but thinking makes it so..." and therein lies the trouble.

Certainly the mind can wend its way through labyrinthine justifications or excuses, exceptions or even denials. The mind likewise can defy logic, ignore reason, and leap from one thought to the next with lightning-like nimble electricity.

What defines good and bad? How do we know one without the other for contrast? How can we lumber our way through life rather than insinuate our way through all the paths of least resistance? What fun it is to ponder!
