  What the directly measured facts of scientific practice seem to tell us, then, is that, although the universe displays varying degrees of habit (that is to say, of partial, varying, approximate, and statistical regularity), the universe does not display deterministic law. It does not directly show anything like total, exact, non-statistical regularity. Moreover, the habits that nature does display always appear in varying degrees of entrenchment or “congealing.” At one end of the spectrum, we have the nearly law-like behavior of larger physical objects like boulders and planets; but at the other end of the spectrum, we see in human processes of imagination and thought an almost pure freedom and spontaneity; and in the quantum world of the very small we see the results of almost pure chance.
