The first three sessions of this Symposium would, I think, lead one to say that if one tried to arrange man on the basis of biological characteristics one would get a continuum; the papers given in this fourth session have shown the ineradicable, or so far ineradicable, tendency of mankind to split themselves up into discontinuous groups.

I personally believe the study of race relations should always be directed to a practical result, that is to enable one to get over this simple human tendency, and to enable us to live together.
