Here are the roots of all the life of the valleys, and here more simply than elsewhere is the eternal flux of nature manifested.

There is a constant flux in the labor-world, which is the result largely, not of special opportunity, but of worth, application, and concentrated thought.

For, once fix the seat of your disorder, and your fancies flux into it like bad humours.

The postulate once formulated, we seek in the flux for confirmations of it, and thus construct a system of 'facts' which are relative to it; that is how the postulate reacts upon experience.

Thus the English system of binding precedents is troublesome enough in a civilization in chronic and violent flux like modern civilization, even when applied to ordinary municipal law which may be changed at will by legislation, but it brings society almost to a stand when applied to the most vital functions of government, with no means at hand to obtain a corrective.

Yet nothing in reality is more of a changing flux than the body in all of its parts and tissues and organs.
