On Dialectic

I was somewhat surprised to learn of the emphasis Stoics placed on dialectic and rhetoric. I had thought even dialectic was relatively unimportant to them, to say nothing of rhetoric. Yet, Diogenes Laertius claims early Stoics valued them both, and texts by Zeno, Chrysippus, and Epictetus partially support this notion. I was quite pleased then, since I recognize the value of dialectic, to see the Stoics attached several virtues to the science of logic and discourse. Non-precipitancy, uncarelessness, irrefutability, and non-randomness.

Zeno of Citium valued both divisions of logic. Dialectic was 'the closed fist' - clarity and brevity. Rhetoric was 'the outstretched hand' - breadth of argument and ability. Chrysippus, naturally, valued them both as well. It seems later Stoics eased off on their support for rhetoric. Certainly it is a useful skill to have, but not essential. Dialectic, however, as far as it comprises definitions and logical analysis is of great necessity to even an amateur philosopher.

I'll end with a strange view on arguments by Zeno. When told not to pass judgement until both sides had spoken, Zeno replied, "The second speaker must not be heard, whether the first speaker proved his case (for the inquiry is then finished) or did not prove it (for that is just like his not having complied when summoned, or his having complied by talking nonsense). But either he proved his case or he did not prove it. Therefore the second speaker must not be heard." I can honestly say I have never heard this take on discourse before, but perhaps there is something to it.
