Abstract
Marcel Proust is not known as a philosopher. Nevertheless, his monumental masterpiece, In Search for Lost Time, must be understood as a System - not a «philosophical System», but a System sustained and moved by a philosophy of existence: «System of existence itself»; «System of time» in its mere occurrence. Memory becomes here, in face of time, an almost sacred way of revealing sense: and sense - the sense that one can see and understand by this work of memory - somehow emerges like a perfect, platonical form, that brings happiness and is wisdom, not as if we have already seen it in a previous life of the soul, but in the process of making its own rememberance and comprehension.
