In other words, while they would in general admit that some kinds of statistical laws are consistent with the assumption of further individual laws operating in a broader context, they believe that quantum mechanics could never satisfactorily be regarded as a law of this kind. The statistical features of the quantum theory are thus regarded as representing a kind of irreducible lawlessness of individual phenomena in the quantum domain. All individual laws (e.g. classical mechanics) are then regarded as limiting cases of the probability laws of the quantum theory, approximately valid for systems involving large numbers of molecules.

At any particular stage in the development of science, our concepts concerning the causal relationships will then be true only relative to a certain approximation and to certain conditions.

We often find that we cannot easily give up the tendency to hold rigidly to patterns of thought built up over a long time. We are then caught up in what may be called absolute necessity. This kind of thought leaves no room at all intellectually for any other possibility, while emotionally and physically, it means we take a stance in our feelings, in our bodies, and indeed, in our whole culture, of holding back or resisting. This stance implies that under no circumstances whatsoever can we allow ourselves to give up certain things or change them.
