It is the language of nature to which one has to listen.

Find things beautiful as much as you can, most people find too little beautiful.

At one time, the earth was supposed to be flat. Well, so it is, even today, from Paris to Asnieres. But that fact doesn't prevent science from proving that the earth as a whole is spherical. No one nowadays denies it. Well...we are still at the stage of believing that life itself is flat, the distance from birth to death. Yet the probability is that life, too, is spherical and much more extensive and capacious than the hemisphere we know.
