ABSTRACT
Natural laws are a statistical truth, which means that they are completely valid only when people are dealing with macro physical quantities. The philosophical principle that underlies our conception of natural law is causality. The term 'probability' therefore refers to the probability on a chance hypothesis. The consensus omnium plays a very important role psychologically; though empirically it is somewhat doubtful, for only in exceptional cases does the consensus omnium prove to be of value in establishing facts. The numinosity of a series of chance happenings grows in proportion to the number of its terms. Kammerer would no doubt have reminded me of his 'seriality'. The strength of an impression, however, proves nothing against the fortuitous coincidence of all these fishes. Schopenhauer believed in the absolute determinism of the natural process and furthermore in a first cause.
