A record, if it is to be useful to science, must be continuously extended, it must be stored, and above all it must be consulted.

Scientific progress on a broad front results from the free play of free intellects, working on subjects of their own choice, in the manner dictated by their curiosity for exploration of the unknown.

A belief may be larger than a fact. A faith that is overdefined is the very faith most likely to prove inadequate to the great moments of life.

Publication has been extended far beyond our present ability to make real use of the record.

Basic scientific research is scientific capital.
