"For psychological interpretation the present is no mere fleeting moment : it holds within it both the past and the future" ; and "space and time do not isolate personality ; they express an order within it." ... But this is to be misled by metaphor. ... The relations of the present to the past and the future, in psychology as elsewhere, are causal relations, not relations of interpenetration. ...Memory does not prolong the existence of the past ; it is merely one way in which the past has effects.
