What we have of systematic and orderly action and speech ... seems to go back to primeval systematic orderliness as found in magic. The scientific te… - Otto Neurath

Carnap, who has so far probably advanced the work of the Vienna Circle the most towards empiricism, made an attempt to create a constitutive constructive system; in this he distinguished two languages: a ‘monologizing’ (phenomenalist) one and an ‘intersubjective’ (physicalist) one. He tries to deduce the physical one from the phenomenalist.

Although what is called ‘philosophical speculation’ is undoubtedly on the decline, many of the practically minded have not yet freed themselves from a method of reasoning, which, in the last analysis, has its roots in theology and metaphysics. No science which pretends to be exact can accept an untested theory or doctrine; yet even in an exact science there is often an admixture of magic, theology, and philosophy. It is one of the tasks of our time to aid scientific reasoning to attain its goal without hindrance. Whoever undertakes this is concerned not so much with ‘philosophy,’ properly speaking, as with ‘anti-philosophy.’ For him there is but one science with subdivisions — a unified science of sciences. We have a science that deals with rocks, another that deals with plants, a third that deals with animals, but we need a science that unites them all.

Overcoming magic often takes the form of theology. From animals and ancestors the path leads to all kinds of spirits. The hypothesis (which already appeared in the magical age) of the little man alongside man, the “soul', and of the special being, 'God', more and more often seeks a parallel process 'behind' processes. Whereas in the magical age, empirically given facts were linked with each other on the basis of primitive theories without the introduction of uncontrollable elements, now their introduction becomes essential.
