We no longer see the evolution of the nervous system, but that of a certain individual. The role of the memory is very important but. . . not as important as we believe. Most of the important things that we do don't depend on memory. To hear, to see, to touch, to feel happiness and pain; these are functions which are independent of memory; it is an a priori thing. Thus, for me, what memory does is to modify that a priori thing, and this it does in a very profound way.
A great mind is a good sailor, as a great heart is.
