A form of intellectual productiveness, therein lies its peculiar charm. Intellectual productiveness is one of the greatest joys - if not the greatest one - of human existence.

I have always a slight feeling of pity for the man who has no knowledge of chess, just as I would pity the man who has remained ignorant of love. Chess, like love, like music, has the power to make men happy.
