The independence of World 3

Among the inmates of my ‘third world’ [World 3] are, more especially, theoretical systems; but inmates just as important are problems and problem situations. And I will argue that the most important inmates of this world are critical argu­ments, and what may be called—in analogy to a physical state or to a state of consciousness—the state of a discussion or the state of a critical argument; and, of course, the contents of journals, books and libraries. …

Let me repeat one of my standard arguments for the (more or less) independent existence of the third world [World 3].

I consider two thought experiments:

Experiment (1). All our machines and tools are destroyed, and all our subjective learning, including our subjective knowledge of machines and tools, and how to use them. But libraries and our capacity to learn from them survive. Clearly, after much suffering, our world may get going again.

Experiment (2). As before, machines and tools are destroyed, and our subjective learning, including our subjective knowledge of machines and tools, and how to use them. But this time, all libraries are destroyed also, so that our ca­pacity to learn from books becomes useless.

If you think about these two experiments, the reality, significance, and degree of autonomy of the third world [World 3] (as well as its effects on the second and first worlds [Worlds 2 and 1]) may perhaps become a little clearer to you. For in the second case, there will be no re-emergence of our civilization for many millenia. [107-8]

Reducing mental to physical states

If mental entities or, better, mental states should exist—and I myself do not doubt that the do exist—then positing mental states is necessary for any true explanation of them; and shoud they one day be reduced to physical states, then this will be a tremendous success. [293]

Objective understanding

I have given here some reasons for the autonomous existence of an objective third world because I hope to make a contribution to the theory of understanding (‘hermeneutics’), which has been much discussed by students of the humanities (‘Geisteswissenschaften’, ‘moral and mental sciences’). Here I will start from the assumption that it is the understanding of objects belonging to the third world which constitutes the central problem of the humanities. This, it appears, is a radical departure from the fundamental dogma accepted by almost all students of the humanities (as the term indicates), and especially by those who are interested in the problem of understanding. I mean of course the dogma that the objects of our understanding belong mainly to the second world, or that they are at any rate to be ex­plained in psychological terms. [162]

Letting our theories die in our stead

As opposed to this, traditional epistemology is interested in the second world [World 2]: in knowledge as a certain kind of belief—justifiable belief, such as belief based upon perception. As a consequence, this kind of belief philosophy cannot explain (and dos not even try to explain) the decisive phenomenon that scientists criticize their theories and so kill them. Scientists try to eliminate their false theories, they try to let them die in their stead. The believer—whether animal or man—perishes with his false beliefs.[122]
