Explorative experimentation brings about manifold conditions and looks for the respective sequels in order to analyse systematically sets of events with respect to condition-sequel relationships. In this setting one has to differentiate between necessary determinant and necessary concomitant conditions as well as accidental concomitant circumstances. The latter are analysed empirically through variations and control (fixing and minimizing) of conditions/circumstances. For this purpose the following methods, proposed by J. S. Mill, can be applied: the methods of agreement and difference, the indirect method of difference, the methods of residues and concomitant variation. They provide a solid background for the development of object-ori ented conceptions leading to the discovery of the laws of inorganic nature. However, they do not lead to the unconstrained determination of the components of condition-sequel relationships.

Among other components, a single ideal experiment within the physical sciences is based on conceptions for experimental settings and preparations of the necessary and sufficient conditions. The explicit prepara tion of such experiments is based on cause-effect relationships and therefore at odds with the assumption of the universal validity of conditional determinism; thus, each true experiment is a proof of the individual au tonomy of the will-power of the human being as experimenter. The seven phases of an individual ideal ex perimental process presented in this paper encompass a subtle interplay of diverse cause-effect and condi tion-sequel relationships. It can be shown that the demand for the reproducible character of an experiment is equivalent to the demand for an individual knowledge process and is not an intrinsic property of the ex periment itself.
