Also known as the Tusculan Disputations, written about the greatness of Rome etc. Cicero states his purpose in Book I, 'prudentiam cum eloquentiam' and 'inlustrandem'.
A short extract, relgious in its veneration and personification of philosphy:
O philosophy leader of life, o thou that searchest out virtue and banishest vice! Could there be without you, not only for us entirely for the life of me?? You have founded cities, you call together the scattered people in the community, you join them amongst themselves first in the home, then in marriage, then by mutual sharing in the written and the spoken word, you creator of law, you have been the teacher of customs and morality, we flee to you, we seek assistance from you, we hand over to you, as previously for the most part, thus now completely (and whole). Moreover one day spent well and in accordance to your laws we must prefer than an eternity of sin. And so whose resources should we use other than you, you who bestowed upon us life and lift away the terror of death?
