Every thinker puts some portion of an apparently stable world in peril and no one can wholly predict what will emerge in its place. - John Dewey

"The "matter" of materialists and the "spirit" of idealists is a creature similar to the constitution of the United States in the minds of unimaginative persons. Obviously the real constitution is certain basic relationships among the activities of the citizens of the country; it is a property or phase of these processes, so connected with them as to influence their rate and direction of change. But by literalists it is often conceived of as something external to them; in itself fixed, a rigid framework to which all changes must accommodate themselves."

Intellectual progress usually occurs through sheer abandonment of questions together with both of the alternatives they assume — an abandonment that results from their decreasing vitality and a change of urgent interest. We do not solve them: we get over them.

Life itself consists of phases in which the organism falls out of step with the march of surrounding things and then recovers unison with it — either through effort or by some happy chance. And, in a growing life, the recovery is never mere return to a prior state, for it is enriched by the state of disparity and resistance through which it has successfully passed. If the gap between organism and environment is too wide, the creature dies. If its activity is not enhanced by the temporary alienation, it merely subsists. Life grows when a temporary falling out is a transition to a more extensive balance of the energies of the organism with those of the conditions under which it lives.
