I do not, however, believe that the better social scientists believe that social sciences are exactly like the physical sciences. I was fortunate to have been an undergraduate in political science and economics at the University of Toronto in 1955 to 1959. I could recall vividly that the faculty, and in particular the chairman, V.W. Bladen, emphasizing the limited scope of pure economics, and the emphasis placed on the humanities in general, and indeed on other areas of the social sciences. I myself regret not having read more psychology.
