Life of Cicero

I am conscious of a certain audacity in thus attempting to give a further life of Cicero which I feel I may probably fail in justifying by any new information; and on this account the enterprise, though it has been long considered, has been postponed, so that it may be left for those who come after me to burn or publish, as they may think proper; or, should it appear during my life, I may have become callous, through age, to criticism.
