Single Idea 20770

[filed under theme 1. Philosophy / D. Nature of Philosophy / 4. Divisions of Philosophy ]

Full Idea

They say that philosophical theory is tripartite. For one part of it concerns nature [i.e. physics], another concerns character [i.e. ethics], and another concerns rational discourse [i.e. logic]

Gist of Idea

Philosophy has three parts, studying nature, character, and rational discourse

Source

report of Zeno (Citium) (fragments/reports [c.294 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.39

Book Ref

'The Stoics Reader', ed/tr. Inwood,B/Gerson,L.P. [Hackett 2008], p.8

A Reaction

Surely 'nature' included biology, and shouldn't be glossed as 'physics'? And I presume that 'rational discourse' is 'logos', rather than 'logic'. Interesting to see that ethics just is the study of character (and not of good and bad actions).
