Stoicism – founded by Zeno of Citium and named after the Stoa, the covered walkway in the Athenian marketplace where this new philosophy was expounded – also saw happiness in terms of tranquillity and, like Epicureanism, its approach centred on ensuring the absence of pain. Stoics taught, along with the Epicureans, that we should limit our desires, and that perceived problems in life are due to errors in judgement about those problems. If we change our attitude, the pain of those external factors can disappear.
