I am firmly convinced to-day that, generally speaking, it is in youth that men lay the essential groundwork of their creative thought, wherever that creative thought exists. I make a distinction between the wisdom of age- which can only arise from the greater profundity and foresight that are based on the experiences of a long life- and the creative genius of youth, which blossoms out in thoughts and ideas with inexhaustible fertility, without being able to put these into practice immediately, because of their very superabundance. These furnish the building materials and plans for the future; and it is from them that age takes the stones and builds the edifice, unless the so-called wisdom of the years may have smothered the creative genius of youth.
