About this source

What it is

This is a moral essay by Seneca, written around 49 CE and addressed to Paulinus, likely a relative of Seneca's wife who held an important grain-supply post in Rome. It survives through later manuscripts and printed editions, including a 1643 Latin edition.

Why it matters

The essay argues that people waste their lives on meaningless pursuits and fail to value time properly, urging a purposeful, present-focused life in line with Stoic philosophy. It reveals Seneca's practical side as an adviser trying to convince a powerful friend to step back from public business, and it remains one of the most quoted texts from ancient philosophy.

Look closer

  • Why might Seneca use examples of famous Romans like Augustus and Cicero to make his argument?
  • What does the essay suggest about how busy, important Romans were expected to spend their time?
  • Why might Seneca have wanted Paulinus in particular to retire early?
