Greek orators

Oratory is one of the earliest necessities of society; as soon as men were organised on terms of equality for corporate action, there must have been occasions when opinions might differ as to the best course to be pursued, and, if there were no inspired king whose unquestioned authority could impose his will, the majority must decide whether to flee or to fight, to kill or to keep alive. Thus different plans must be discussed, and, in cases where opinion was evenly balanced, that side would prevail which could state its views most convincingly; and so the need for deliberative oratory arose.
