Steven Hayward writes,
for Progressive politics, the positivist distinction between facts and values, which corresponds to the distinction between administrative questions and political questions. . .preserves for the rulers alone freedom of choice and action. The “scientific” elites of the administrative state
I am taking this quote quite out of context. Please read the entire essay.
Back when I took Introduction to Philosophy, the professor taught positivism as an approach to epistemology, which deals with the question of how we know what is true. The positivist answer is that there is logical knowledge and empirical truths. Logical truths are embedded in the definitions of terms. Empirical knowledge comes from observation. Statements that are neither logical nor empirical are dogma.
The term dogma is meant to apply to statements such as “Jesus is the son of God,” or “Sodomy is wrong.”
Nowadays, it seems that what positivism means to Hayward (and others, including McCloskey) is the doctrine that we can and should separate fact from opinion, knowledge from preference, the news page from the editorial page. It links to progressivism in that the progressive imagines an ideal political system as one in which the voting public expresses preferences and then the experts with the knowledge design and execute policies to satisfy those preferences. It links to orthodox American economics, because those economists have always thought of themselves as having the knowledge needed in order to play the expert role.
Note that the progressive model cannot handle a situation in which the public expresses a preference not to be governed by experts. Such a preference does not compute.
There are some heterodox economists on the left and the right who deny that the facts/values distinction can be maintained. I think they have a point.
Let’s take as an example the effect of the minimum wage on employment. In principle, the question of how the minimum wage affects employment falls on the “facts” side of the facts/values divide. In practice, I think it is fair to say that the easiest way to predict where an economist will come out on the question of how the minimum wage affects employment is to find out where the economist stands on some other issue that divides left and right. So an economist who supports a higher military budget is likely to predict a larger adverse effect of an increase in the minimum wage on employment than economist who supports a smaller military budget. That is because the military spending issue and minimum wage policy “affiliate” with one another, even though they have essentially nothing to do with each other.
Still, I do not have a problem with the facts/values distinction in principle. I do not mind if economists try to keep facts and values separate, however much this tends to fail in practice. What I object to the most is the claim that economists have expertise that enables them to operate the administrative state as it exists today.
