What we really mean by free will... is the visualizing of alternatives and making a choice between them. ...the central problem of human consciousnes… - Jacob Bronowski

All great scientists have used their imaginations freely, and let it ride them to outrageous conclusions without crying "Halt!"

And when we describe it as I shall do, it becomes plain that imagination is a specifically human gift. To imagine is the characteristic act, not of the poet's mind, or the painter's, or the scientist's, but of the mind of man.

The air in a man's lungs contains 10,000,000,000,000,000,000,000 atoms, so that sooner or later every one of us breathes an atom that has been breathed before by anyone you can think of who has ever lived — Michelangelo or George Washington or Moses.
