philosophical enquiry, this mode of composition was well adapted, if not
to the discovery, at least to the confirmation of moral truth; especially
as the practice was then not uncommon, for speculative men to converse
together on important subjects, for mutual information. In treating of
any subject respecting which the different sects of philosophers differed
(64) from each other in point of sentiment, no kind of composition could
be more happily suited than dialogue, as it gave alternately full scope
to the arguments of the various disputants. It required, however, that
the writer should exert his understanding with equal impartiality and

dialogues of Cicero, he manages the arguments of the several disputants
in a manner not only the most fair and interesting, but also such as
leads to the most probable and rational conclusion.

After enumerating the various tracts composed and published by Cicero, we
have now to mention his Letters, which, though not written for
publication, deserve to be ranked among the most interesting remains of
Roman literature. The number of such as are addressed to different
correspondents is considerable, but those to Atticus alone, his
confidential friend, amount to upwards of four hundred; among which are
