His creator has said that he has always conceived and thought of the life of his hero and of the book as a river.

The river is explored as though it were absolutely uncharted. Nothing that has ever been said or thought of life is accepted without being brought to the test of Jean-Christophe's own life. What is not true for him does not exist; and, as there are very few of the processes of human growth or decay which are not analysed, there is disclosed to the reader the most comprehensive survey of modern life which has appeared in literature in this century.
