I now imagine a quantum theoretician who may even admit that the quantum-theoretical description refers to ensembles of systems and not to individual systems, but who, nevertheless, clings to the idea that the type of description of the statistical quantum theory will, in its essential features, be retained in the future. He may argue as follows: True, I admit that the quantum-theoretical description is an incomplete description of the individual system. I even admit that a complete theoretical description is, in principle, thinkable. But I consider it proven that the search for such a complete description would be aimless. For the lawfulness of nature is thus constituted that the laws can be completely and suitably formulated within the framework of our incomplete description.

From the preceding examples, we may get some idea of the change in perspective that may occur in our reading and interpretation of the philosophical works of antiquity when we consider them from the point of view of the practice of spiritual exercises. Philosophy then appears in its original aspect: not as a theoretical construct, but as a method for training people to live and to look at the world in a new way. It is an attempt to transform mankind. Contemporary historians of philosophy are today scarcely inclined to pay attention to this aspect, although it is an essential one. The reason for this is that, in conformity with a tradition inherited from the Middle Ages ... they consider philosophy to be purely abstract-theoretical activity.
Pierre Hadot
Speaking as of today, I do not consider it intellectually respectable to be a partisan in matters of religion. I see religion as I see such other basic fascinations as art and science, in which there is room for many different approaches, styles, techniques, and opinions. Thus I am not formally a committed member of any creed or sect and hold no particular religious view or doctrine as absolute. I deplore missionary zeal, and consider excessive dedication to and advocacy of any particular religion, as either the best or the only true way, an almost irreligious arrogance. Yet my work and my life are fully concerned with religion, and the mystery of being is my supreme fascination, though, as a shameless mystic, I am more interested in religion as feeling and experience than as conception and theory.
Alan Watts
As the natural sciences have developed to encompass increasingly complex systems, scientific rationality has become ever more statistical, or probabilistic. The deterministic classical mechanics of the enlightenment was revolutionized by the near-equilibrium statistical mechanics of late 19th century atomists, by quantum mechanics in the early 20th century, and by the far-from-equilibrium complexity theorists of the later 20th century. Mathematical neo-Darwinism, information theory, and quantitative social sciences compounded the trend. Forces, objects, and natural types were progressively dissolved into statistical distributions: heterogeneous clouds, entropy deviations, wave functions, gene frequencies, noise-signal ratios and redundancies, dissipative structures, and complex systems at the edge of chaos.

I now saw, that a science is either deductive or experimental, according as, in the province it deals with, the effects of causes when conjoined, are or are not the sums of the effects which the same causes produce when separate. It followed that politics must be a deductive science. It thus appeared, that both Macaulay and my father were wrong; the one in assimilating the method of philosophising in politics to the purely experimental method of chemistry; while the other, though right in adopting a deductive method, had made a wrong selection of one, having taken as the type of deduction, not the appropriate process, that of the deductive branches of natural philosophy, but the inappropriate one of pure geometry, which, not being a science of causation at all, does not require or admit of any summing-up of effects.
John Stuart Mill
The need for a fundamentally different approach to the study of physical processes at the molecular level motivated the development of relevant statistical methods, which turned out to be applicable not only to the study of molecular processes (statistical mechanics), but to a host of other areas such as the actuarial profession, design of large telephone exchanges, and the like. In statistical methods, specific manifestations of microscopic entities (molecules, individual telephone sites, etc.) are replaced with their statistical averages, which are connected with appropriate macroscopic variables. The role played in Newtonian mechanics by the calculus, which involves no uncertainty, is replaced in statistical mechanics by probability theory, a theory whose very purpose is to capture uncertainty of a certain type.
