Causality in Statistical Theories as an Example for the Idealization of Physical Laws,doubts about the applicability of this proposal as a general criterion, it often describes the behaviour of scientists even in the case when the two theories do not describe the facts “equally well”: In practical work physicists usually tolerate a larger margin of inaccuracy if they can only use a “

Stable Axioms in Physical Theories,rm. In the words of R. Thom [1]: “Une G-forme A sera dite . si toute form B assez voisine de A. est G-équivalente a A.”. (R. Thorn considers a pseudo-group G operating on forms.) In physics one often deals with stability of ., e.g. of orbits under small perturbations or of thermodynamical states und

Approximative Reduction by Completion of Empirical Uniformities,istic theories of spacetime and dynamics, or of classical to corresponding quantum theories. To formalize the idea of theory approximation one needs a mathematical structure with a certain type of convergence — the Cauchy convergence, which is defined on a uniform structure (comp. [9], [10], [11]).

,G. Ludwig’s Positivistic Reconstruction of the Physical World and His Rejection of Theoretical Concanalytical philosophers of science. We shall find striking similarities between Ludwigs philosophy of physics and the neopositivist account of the Vienna Circle before world war II. Ludwig started his philosophical investigation of physics quite independently of the analytical philosophical traditio

Abstraction, Idealization and Approximation,t every proposition has one of two truth-values, either true or false. Hence, if there are propositions the truth-values of which are not decidable in principle, anti-realism perhaps in the form of intuitionism or verificationism is epistemologically a more reasonable position than unrestricted real

,Sneed’s Theory Concept and Vagueness,es the following problem. There are practically no utterances of practising scientists about the relation of theory and approximation which could serve as ‘data’ against which the meta-discussion might be ‘tested’. This is not to say that approximation is not relevant for physics: the very first lab

Mystical Realism,ical terms is the same, namely two [14, 16]. Second, in all the abstract treatments of theoreticity, the theoretical terms are indexed from r to n (r < n). Are there always only two theoretical terms? If not, what happens when the theoretical vocabulary gets largs, is it simply a matter of letting a
