““What is the Vienna Circle?” is a question which is neither rhetorical nor trivial. It is perhaps an attempt to ‘square the circle’ – which is, meanwhile, mathematically possible, as Karl Menger described as early as 1934.
This question might be also a problem of how the whole relates logically to the parts or the parts to the whole, which was already addressed by mereology (whole-part theory) according to Stanislaw (1916).
Of course, we are all familiar with the irritating fact that one and the same phenomenon can be described consistently by more than one theory”

Context: The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation.
