The solution often turns out more beautiful than the puzzle.

I accept that there may be things far grander and more incomprehensible than we can possibly imagine.

Biology is the study of the complex things in the Universe. 

Physics is the study of the simple ones.

Evolution has no long-term goal. 

There is no long-distance target, 

no final perfection to serve as a criterion for selection, 

although human vanity cherishes the absurd notion 

that our species is the final goal of evolution.

The essence of life 

is statistical improbability 

on a colossal scale.

We are moved to tears by a beautiful piece of music

and we describe the performance as 'magical'.

We gaze up at the stars on a dark night with no moon and no city lights

and, breathless with joy, we say the sight is 'pure magic'.
