“Reminiscences, even extensive ones, do not always amount to an autobiography.... For autobiography has to do with time, with *sequence* and what makes up the continuous flow of life. Here, I am talking of a space, of moments and discontinuities. For even if months and years appear here, it is in the form they have in the moment of recollection. This strange form—it may be called fleeting or eternal—is in neither case the stuff that life is made of.”

—Walter Benjamin (1892–1940)

“The absence of the beloved, *short* though it may last, always lasts too long.”

—Molière [Jean Baptiste Poquelin] (1622–1673)

“The really great novel ... tends to be the *exact* negative of its author’s life.”

—André Maurois (1885–1967)
