The two psychologies: is mind a causal object for natural science, while the free, purposive, valuing self belongs to a philosophy science cannot reach?

Hugo Münsterberg, answered from the texts and cited to the page.

The position in brief

There are two ways of regarding the mind, and the confusion of them is the source of endless error. As a natural scientist, I treat mental life as an object: a series of contents — sensations, images, feelings — to be explained, like any natural fact, by their antecedent physical and psychological conditions, in a strict causal chain, with no room for freedom or purpose as scientific categories.¹²³⁴

This is causal psychology, and all my applied work — the testing, the selection, the study of fatigue — is done wholly within it, for there mind is an object to be predicted and controlled. But this is not the whole truth of mental life, nor its deepest truth. The self of real life is not an object among objects; it is a subject that takes attitudes, wills, and values — free not as an exception to causal law but as belonging to an entirely different order, the order of purpose and of over-personal, eternal values, which no causal science can reach or reduce.⁵

The scientist rightly brackets freedom; the philosopher rightly preserves it. Keep the two standpoints apart, and the reality of the valuing self is safe from the determinism that is proper, and only proper, to the science.

1. That means that it treats the inner experience like objects. They are then simply contents of consciousness, which must be analyzed into their elements in the same way in which the anatomist dissects the body into its tissues and the tissues into their cells. And, finally, those contents of consciousness are to be explained as the physicist explains the changes in the contents of space.

2. The situation is this. In our immediate life-reality, which the poet expresses, which the historian interprets, and in which our legal or political or moral or social interests lie, we feel ourselves as personalities, and as such characterized by our unity, by our freedom, and by our purposiveness.

3. That inner life which man values and wants to see superior to the mere mechanism of matter is not the mind conceived in the thought form of causality. The mere mental processes as such have no dignity, since they are not the real inner life, hut are merely scientific constructions which we need as counters for our calculaUon.

4. How these two standpoints can be harmonized in the unity of a life philosophy is not our problem here. But a mixture of the two would be neither science nor religion. It would spoil physics by mysticism and would destroy spiritual religion by materialism. We demanded at the threshold of our work that the psychologist be equally consistent.

5. We may know little about that postulated causal world, but we are sure beforehand that whatever the future may discover about it must belong to the causal system, or it is wrong. We are free to choose the point of view, but when we have chosen it we are bound by its presuppositions.

Where the argument is made

• Psychology: General and Applied (1914 — causal versus purposive psychology, the action theory)
• the philosophical works on values (The Eternal Values, Science and Idealism)

How the argument was received

Münsterberg's two-standpoint dualism — causal natural-science psychology versus a purposive philosophy of the free, valuing self — draws on the neo-Kantian distinction (Windelband, Rickert) between the explanatory natural sciences and the sciences of value and understanding, and it was influential in his day. It was largely bypassed by the twentieth-century mainstream: behaviorism and later cognitive science pursued the causal science without the idealist counterpart, and Münsterberg's action theory and his philosophy of eternal values fell out of fashion. The distinction survives in transformed form in the modern debate between causal explanation and interpretive understanding, and in compatibilist and two-level responses to the free-will problem. The standing objection is that a two-standpoint dualism, by assigning freedom and value to a separate order sealed off from science, may preserve them by fiat rather than reconcile them with the causal picture — evading the mind-body and freedom problems rather than solving them.
