Gilles Deleuze believed that the focus of Proust was not memory and the past but the narrator's learning the use of "signs" to understand and communicate ultimate reality, thereby becoming an artist. While Proust was bitterly aware of the experience of loss and exclusion—loss of loved ones, loss of affection, friendship and innocent joy, which are dramatized in the novel through recurrent jealousy, betrayal and the death of loved ones—his response to this, formulated after he had discovered Ruskin, was that the work of art can recapture the lost and thus save it from destruction, at least in our minds. Art triumphs over the destructive power of time. This element of his artistic thought is clearly inherited from romantic platonism, but Proust crosses it with a new intensity in describing jealousy, desire and self-doubt. (Note the last quatrain of Baudelaire's poem "Une Charogne": "Then, O my beauty! say to the worms who will / Devour you with kisses, / That I have kept the form and the divine essence / Of my decomposed love!").
