Between the conception and the creation, between the emotion and the response, Falls the shadow.
T. S. EliotThe river itself has no beginning or end. In its beginning, it is not yet the river; in the end it is no longer the river. What we call the headwaters is only a selection from among the innumerable sources which flow together to compose it. At what point in its course does the Mississippi become what the Mississippi means?
T. S. Eliot
