Diogenes Laertius, Stoicorum Veterum Fragmenta
- Stoicorum Veterum Fragmenta: SVF II.38b: "Philosophy, they say, is like an animal: logic corresponding to the bones and sinews, ethics..."
Stoicorum Veterum Fragmenta is a collection of fragments and testimonia of the earlier Stoics composed in 1903–1905 by Hans von Arnim. It includes the fragments and testimonia of Zeno of Citium, Chrysippus and their immediate followers. At first the work consisted of three volumes, to which Maximilian Adler in 1924 added a fourth, containing general indices.
