To explain, I will exhibit the heads of Seneca's and Cicero's philosophical works, the most extensive of any we have received from the ancients. Of ten heads in Seneca, seven relate to ourselves, viz. de ira, consolatio, de tranquilitate, de constantia sapientis, de otio sapientis, de vita beata, de brevitate vitae; two relate to others, de elementia, de beneficiis; and one relates to the government of the world, de providentia. Of eleven tracts of Cicero, five respect ourselves, viz. de finibus, Tusculana, academica, paradoxa, de Senectute; one, de officiis, relates partly to ourselves, partly to others; one, de amicitia, relates to others; and four are on different subjects, to wit, de natura deorum, de divinatione, de fato, and somnium Scipionis.
