De Fato (English: "Concerning Fate") is a partially lost philosophical treatise written by the Roman orator Cicero in 44 BC.

[1][2] It takes the form of a dialogue, although it reads more like an exposition,[1][3] whose interlocutors are Cicero and his friend Aulus Hirtius.

[1][3] In any case, the work would have most likely been completed prior to Cicero's abortive departure for Greece in July of that year.

Therefore neither assent nor action is in our power; and from this it follows that neither praise nor blame are just, nor honours nor punishment"[11]Cicero essentially dismisses this proposition as antithetical to what is observed, but postulates freedom as a necessity for moral life.

[6] Ultimately, Cicero maintains this position as he is emotionally convinced that it is in man's power to achieve virtue for himself; if determinism were the order of things, then such ability would not be true.
