The ghostly presence of virtual particles defies rational common sense and is nonintuitive for those unacquainted with physics. Religious belief in God, and Christian belief that God became Man around two thousand years ago, may seem strange to common-sense thinking. But when the most elementary physical things behave in this way, we should be prepared to accept that the deepest aspects of our existence go beyond our common-sense intuitions.
Octave Mirbeau
To take something from a person and keep it for oneself: that is robbery. To take something from one person and then turn it over to another in exchange for as much money as you can get: that is business. Robbery is so much more stupid, since it is satisfied with a single, frequently dangerous profit; whereas in business it can be doubled without danger.
