Cicero on Friendship and Trust
“A friend is, as it were, a second self.” — Cicero, legal mind of Rome, put it in pure Latin: «Amicus est tamquam alter idem.»

Cicero, in De Amicitia (On Friendship), writes: «Amicus est tamquam alter idem.» — “A friend is, as it were, a second self.” In a city where enemies outnumbered allies, Cicero made friendship a sacred, almost philosophical bond.
More than dinner-party loyalty.
To Cicero, friendship is rare because it demands total trust. You recognize yourself in the other, risk their downfall as your own, and speak truth even when it stings. For a politician who fell from grace, friends were not just luxuries — they were lifelines and, sometimes, the blade.
Cicero trusted almost no one — and paid the price. His definition of friendship is scarcer, and sharper, than any social network today.
