As he said...
before dropping out of a plane.
"Consider this my friend. The human being may be no more real than is a cinematograph film. When the projected light is switched off all that remains is a blank screen. That which has been projected by light was a series of 'stills'. Such also is what is beng projected by 'life'. The more you consider the analogy the more perfect it seems to be: it could help us to understand"
Then he let go, with a grin.
