Сторінка 103 - For failings he had undoubtedly — many of us remember them; we are this day considering the effect of them. But he had no failings which were not owing to a noble cause; to an ardent, generous, perhaps an immoderate, passion for fame; a passion which is the instinct of all great souls.
