Yes, if a memory, thanks to forgetfulness, has been unable to contract any tie, to forge any link between itself and the present, if it has remained in its own place, of its own date, if it has kept its distance, its isolation in the hollow of a valley or on the peak of a mountain, it makes us suddenly breathe an air new to us just because it is an air we have formerly breathed, an air purer than that the poets have vainly called Paradisiacal, which offers that deep sense of renewal only because it has been breathed before, inasmuch as the true paradises are paradises we have lost. ☛ PROUST, Marcel (1927).
