We live in a world which is an impressive and irresistible mixture of sufficiencies, tight completenesses, order, recurrences which make possible prediction and control, and singularities, ambiguities, uncertain possibilities, processes going on to consequences as yet indeterminate. They are mixed not mechanically but vitally like the wheat and tares of the parable. We may recognize them separately but we cannot divide them, for unlike wheat and tares they grow from the same root. Qualities have defects as necessary conditions of their excellencies; the instrumentalities of truth are the causes of error; change gives meaning to permanence and recurrence makes novelty possible. A world that was wholly risky would be a world in which adventure is impossible, and only a living world can include death.

— John Dewey, Experience and Nature (1929, 43)
