Scientism in the Way of Science

by Gene Callahan

I repeatedly find attacks on positions in the social sciences made based on extremely limited and, frankly, antiquated views of how the physical sciences proceed. I will give one example from a rightist criticism of a leftist view, and one that is a leftist criticism of a rightist view, to illustrate that my point has nothing to do with ideology — or perhaps, that it has to do with the way ideology can lead one to embrace flimsy criticisms of other’s positions.

The first excerpt is from Hunter Lewis’s book, Where Keynes Went Wrong:

“In chapter 15, we saw how Keynes wrote N = F(D), which means that employment, denoted N, is a function of demand. Demand however is defined as expected sales, not actual sales. We noted that expectations are not a measurable quantity and thus do not belong in an equation.”

Well, one way to measure these expectations would be to walk around and ask the entrepreneurs “How much do you expect to sell this year?” then total up those amounts. Why in the world this would not be a fine measurable quantity is unclear.

What is Science?

by Jerry O’Driscoll  

Some recent controversies move me to take up the topic within the limitations of a blog post.  Many years ago (1956), Fritz Machlup ably addressed the issue in an essay titled “The Inferiority Complex of the Social Sciences.”  He rejected limiting the term science to particular subject matters or methods.  He concluded that “there is no epistemologically defensible borderline short of the widest meaning of scientific method, defined in the Encyclopedia Brittanica as ‘any mode of investigations by which impartial and systematic knowledge is acquired.’”  

I endorse Machlup’s broad definition of science as any systematic study of a subject.  As he observed in a footnote, the German Wissenschaft is more inclusive: “the historians of literature, the philologists, the philosophers, the mathematicians, the sociologists, they are all scientists (Wissenschaftler).” In French, science is knowledge and one can speak of la science infuse, intuitive knowledge. La science de l’art is simply the systematic study of art.
