Tria Genera Causarum

Extract

The early handbooks of rhetoric compiled by Tisias and Corax and their successors seem to have been directed entirely at successful speaking in courts of law. This was the art that Strepsiades set out to learn in the Philosopher's Thinking-shop; this, Isocrates complains, was the only object of technical writers on rhetoric before his time; and Aristotle, when he wrote the chapter that stands first in hisRhetoric, made just the same complaint: τ⋯ς αὐτ⋯ς oὔσμς μεθ⋯δoυ περι τ⋯ δημηγoρικτ⋯ και δικανικ⋯ και καλλιoνoς και πoλιτικωτ⋯ραςτ⋯ς δημηγoρικ⋯ς πραγματειας oὔςηρ ἤ oὔσης ἤ τ⋯ς περι τ⋯ ςυναλλ⋯γματα, πει μ⋯ν ⋯κεινης oὐδ⋯ν λ⋯γoυγι, περι δ⋯ικ⋯ξεσθαι π⋯ντες πειρ⋯νται τεχνoλoγειν. The art as the Sophists practised it was by no means so limited in its application: many of them were accustomed to playing the parts of statesmen and diplomats as well as of educators; and the most notorious field for their powers of oratory was of course the lecture or ⋯πιδειξις. But the systems of rhetoric that they devised and taught did not cover their own practice; and forensic oratory, as well as seeming the most commonly necessary kind at that time, was also, it must be said, the easiest to reduce to rule. Gorgias, it is true, professed to teach a rhetoric of more extended application, by means of which his pupils would be able to produce conviction in any public assembly;* but we must conclude that this wider field was at least very imperfectly treated in all the technical systems of the time. Plato shortly describes the position thus:μ⋯λιστα μ⋯ν πως περι τ⋯ς δικας λ⋯γεται τε και γρ⋯φεται τ⋯χνῇ, λ⋯γεται δ⋯ και περι δημηγoριας ‧ ⋯π ι πλ⋯o≠ δ⋯ oκ⋯κoα.
