Valuing communication.

In meditations on the impossibility of knowledge, the ancient sophist, Gorgias, arrives at a conclusion that makes the most optimistic slump in their chair; even if knowledge is possible, it will not be possible to communicate it (Fragment 83). In a less pessimistic mood, Gorgias was rumoured to have taught classical physicians rhetorical skills including the ability to persuade their patients to pay for their services in a timely manner, methods of communication to advertise the physician's prowess, and techniques to encourage patients to particular regimens.
