One of the most effective ways to communicate ideas is through rhetoric. The art of rhetoric to large groups of people is called public oration. Like any skill, public oration requires practice in order to be effective. The more one practices, the better one's public speaking will be.
In modem democratic society, public speaking is the primary method of communication. Those who have good rhetorical skills find that they can persuade others of their points of view, while those who cannot speak well are not taken seriously. Those who wish to exert influence over community or society must develop strong speaking ability.
There are two approaches available to develop speaking skills. The first is through logical argument. This involves deriving valid conclusions from premises one can most clearly delineate as being true or correct. Sophistry is the second form. Sophistry involves using rhetorical devices (such as drama) or fallacious reasoning to support arguments, whether such arguments are good or bad. This first approach is in accordance with truth, while the second is degenerate.
People should obviously strive to cultivate speaking skills via the logical argument method.
Sophists are wrong in principle, but identifiable by careful listeners. Logical argumentation is not always easy, but with practice, one will be speaking clearly and precisely.
