Full Idea
All things come into being according to this Law ('logos'), ...and I expound theories (words) and processes (actions) separating each thing according to its nature and explaining how it is made.
Gist of Idea
Logos is the source of everything, and my theories separate and explain each nature
Source
Heraclitus (fragments/reports [c.500 BCE], B001), quoted by Sextus Empiricus - Against the Mathematicians 7.133
Book Reference
'Ancilla to the Pre-Socratic Philosophers', ed/tr. Freeman,Kathleen [Harvard 1957], p.24
A Reaction
I like the fact that things are separated according to their natures (particulars!), and not that natures are somehow bestowed on individuals.
