"As soon as an object is regarded as a dynamic entity, then analysis and definition become both difficult and unsatisfactory. Thinking is under such circumstances well-nigh impossible for most people. To think at all logically, no matter how concretistic the thought may be, there must be some static point. Where, now are we to look for this point? The man of action answers, in its effect. Then an object becomes completely separated... from all other objective elements as well as from the perceiving self. ...Reality, in other words, is pragmatic. ...Like all other philosophers, he [the thinker, as opposed to the man of action] is... aware of the movement and the shifting form of things. He is as much impressed by this as the man of action. But the world must first be static and objects must first take on a permanent or, at least, a stable form before one can deal with them systematically. ...The attempts of these primitive thinkers are embodied in numerous creation myths... the task is always the same—an original, moving, shapeless or undifferentiated world must be brought to rest and given stable form. ...There exist, however, many things that manifestly do not have permanence of form and do look different at different times. Philosophers have always given the same answer to this problem and predicated a unity behind these changing aspects and forms."
