Zum Verhältnis zwischen Experiment und Gedankenexperiment in den Naturwissenschaften

Abstract

To understand the reciprocal autonomy and complementarity of thought and real experiment, it is necessary to distinguish between a 'positive' (empirical or formal) and a transcendental perspective. Empirically and formally, real and thought experiments are indistinguishable. However, from a reflexive- transcendental viewpoint thought experiment is at the same time irreducible and complementary to real experiment. This is due to the fact that the hypothetical-anticipatory moment is in principle irreducible to physical reality-even though it refers to physical reality and is bound with the empirical use of our understanding. The presence of counterfactuals is the condition of the possibility for thought experiments to become in principle real ones, by means of a series of technical realisations that gradually approximate the idealisations that they contain. © 2007 Springer Science+Business Media, Inc.
