A collection of letters attributed to Plato, mostly addressed to Dionysius II of Syracuse and the circle around Dion, defending his political interventions in Sicily.
The Letters are a set of epistles traditionally ascribed to Plato, the bulk of them concerning his repeated, disastrous involvement in the politics of Syracuse under the tyrants Dionysius I and Dionysius II. Plato was drawn to Sicily by his friend Dion, who hoped that philosophy might tame or educate a young ruler into something like a philosopher-king. The letters record the wreckage of that hope: broken promises, exile, slander, and a friendship between Dion and Dionysius that curdled into open hostility, with Plato caught in between and blamed by both sides.
The most substantial pieces are addressed to Dionysius himself. In them Plato defends his own conduct point by point -- why he first refused to get involved in Syracusan politics, why he eventually sailed back a second and third time, and why he will not take credit or blame for policies he never endorsed. He also drops into deliberately cryptic language about "the nature of the First" and a philosophical doctrine too dangerous or too easily garbled to commit fully to writing, warning Dionysius to burn the letter after reading it. Woven through the political self-justification is ordinary correspondence: requests to place tutors, arrange dowries for grandnieces, settle debts, buy a statue of Apollo, and send tunics and armor to friends.
The collection matters less as systematic philosophy than as a rare (if disputed) first-person window onto Plato's life -- his claim that philosophers must engage with power cautiously, his account of watching a real experiment in philosopher-kingship fail in real time, and his insistence that he never wrote a treatise on his deepest teaching, so that "there is no treatise by Plato, nor will there ever be." Scholars have long debated how much of the collection is genuinely his; Letter VII is generally considered the most likely to be authentic and is the source of most of the political narrative.
“The greatest safeguard is not to write it down but to learn it by heart; for it is not possible for what is written not to leak out.”

They are a collection of epistles, mostly addressed to Dionysius II, the tyrant of Syracuse, defending Plato's conduct during his repeated trips to Sicily to advise Dionysius and mediate between him and Dion. They mix political self-justification with personal and financial requests.
Authorship is disputed among scholars; Letter VII is the one most often accepted as genuinely Plato's, since it contains the fullest and most consistent account of his Sicilian ventures. Others in the collection are treated with more skepticism, though they were transmitted alongside his dialogues since antiquity.
Dion was Plato's friend and host in Syracuse, and the man who first invited Plato to try to educate the young Dionysius II into philosophical rule. The letters trace how Dion and Dionysius fell out, with Dion eventually exiled, and Plato repeatedly tries and fails to reconcile them.
No -- in Letter II he insists that he has never written a treatise on his deepest philosophical doctrine and never will, because anything written down can "leak out" to people unprepared for it, and he instructs Dionysius to burn the letter after reading it.
He argues that wisdom and power naturally seek each other out, and that he went to Syracuse hoping philosophy could shape a ruler into something better than a tyrant, but he also warns that great power breeds slanderers and that philosophers must engage with such power warily.
