Seneca's Wisdom Is the Hallmark of Roman Stoicism

Seneca is perhaps the greatest figure in the history of stoicism, apart from chrysippus. His philosophy pivots around this notion that our interior life, and nothing else, is truly up to us. The power of seneca's teaching lies in the promise that with patience and practice we can reshape ourselves so that we really are under our own control. But this requires us to renounce our obsessions with things that are not under our control.
