Leadership
Leadership is both a research area and a practical skill encompassing the ability of an individual or organization to "lead" or guide other individuals, teams, or entire organizations. Specialist literature debates various viewpoints, contrasting Eastern and Western approaches to leadership, and also (within the West) United States versus European approaches. U.S. academic environments define leadership as "a process of social influence in which a person can enlist the aid and support of others in the accomplishment of a common task". Leadership seen from a European and non-academic perspective encompasses a view of a leader who can be moved not only by communitarian goals but also by the search for personal power.
Rhetoric
Rhetoric is the art of discourse, wherein a writer or speaker strives to inform, persuade or motivate particular audiences in specific situations. It can also be in a visual form; as a subject of formal study and a productive civic practice, rhetoric has played a central role in the European tradition. Its best known definition comes from Aristotle, who considers it a counterpart of both logic and politics, and calls it "the faculty of observing in any given case the available means of persuasion." Rhetoric typically provides heuristics for understanding, discovering, and developing arguments for particular situations, such as Aristotle's three persuasive audience appeals, logos, pathos, and ethos. The five canons of rhetoric, which trace the traditional tasks in designing a persuasive speech, were first codified in classical Rome: invention, arrangement, style, memory, and delivery. Along with grammar and logic (or dialectic – see Martianus Capella), rhetoric is one of the three ancient arts of discourse.
Leadership
Character in many ways is everything in leadership. It is made up of many things, but I would say character is really integrity. When you delegate something to a subordinate, for example, it is absolutely your responsibility, and he must understand this. You as a leader must take complete responsibility for what the subordinate does. I once said, as a sort of wisecrack, that leadership consists of nothing but taking responsibility for everything that goes wrong and giving your subordinates credit for everything that goes well.
Dwight D. Eisenhower, as quoted in Nineteen Stars : a Study in Military Character and Leadership (1971) by Edgar F. Puryear Jr.
Rhetoric
Concerning the utility of Rhetoric, it is to be observed that it divides itself into two; first, whether Oratorical skill be, on the whole, a public benefit, or evil; and secondly, whether any artificial system of Rules is conducive to the attainment of that skill.
