Cicero Quotes About Trust

De Amicitia, chapter 21 / classical section 80, Andrew P. Peabody translation, Project Gutenberg #7491. Laelius says that unless self-love is transferred into friendship a true friend cannot be found, “for such a friend is, as it were, another self.” The familiar another-self formulation is presented in its philosophical context and not as a literal identity claim.

De Amicitia, chapter 8 / classical section 27, Andrew P. Peabody translation, Project Gutenberg #7491.

De Amicitia, chapter 6 / classical section 22, Andrew P. Peabody translation, Project Gutenberg #7491. “Friendship has more advantages than I can easily name” introduces Laelius’ catalogue of the many uses and consolations of friendship; the open-ended praise remains rhetorical/philosophical rather than a quantified claim about relationship outcomes.

Peabody translation, Project Gutenberg #7491. “Firm, steadfast, self-consistent men are to be chosen as friends” follows Laelius’ recollection of Scipio’s concern that people test possessions more carefully than friendships.
