Aristotle: Someone asked whether playing a good game of chess depends on talent or chess skills. My opinion is that hard study without abundant talent, and talent without training, are useless. The two should serve each other and combine with each other.

Kant: There are two things that the more often we think about them over and over, the more they infuse people's hearts with admiration and awe that are constantly renewed and unabated. This is the chess piece in my hand. The rules of chess in your mind.

Sumlinsky: To be a river of fiery emotions and calm reason, and not to make hasty decisions. This is one of the sources that the art of chess will never dry up.

Shelley: A shrewd person is a person who carefully considers his own chess game, and a wise person is a person who carefully considers other people's chess games.
