The time of the Reverie. Memory and duration in Rousseau

There are three modes adopted by the temporal succession to which we are subjected: succession of desires, succession of identities and succession of instants. But happiness is a permanent state; therefore, it is not a state that corresponds to man. We propose that succession is the horizon from which Rousseau thinks about the possibility of happiness that, being discontinuous and brief, can achieve a permanence that results from another experience of time that we will call duration. Our hypothesis is: firstly, that this possibility is available thanks to memory given over daydream (rêverie); secondly, that this memory is a memory of love because love, like happiness, aspires to eternity. We examine the main feature of duration, that is: the past is preserved in the present without being confused with it, just as each past note of a melody is somehow preserved in the present one. Past times are never lost times. We consider two discoveries by Rousseau, the sensitive memory and the memorious imagination, to show the interplay between memory and personal identity. Finally, we venture a comparison with the duration according to Bergson through the metaphor of a symphony and we confront this memory in love with the memory of pain inaugurated by Nietzsche in his Genealogy of Morality.
