If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it.

A man's value to the community primarily depends on how far his feelings, thoughts, and actions are directed towards promoting the good of his fellows.

Development of Western science is based on two great achievements: the invention of the formal logical system (in Euclidean geometry) by the Greek philosophers, and the discovery of the possibility to find out causal relationships by systematic experiment (during the Renaissance).
