Rhetoric flourished during the period of ancient Greece and Rome, when it was taught by renowned speakers such as Demosthenes, Cicero, Aristotle, Quintilianus and Plato. The second half of the 20th century witnesses the second peak of rhetoric, that is, the art of public speaking. Man is a thinking being, and the basis of every social relationship is communication. What makes a good speaker and what does a good speech look like are questions that are frequently raised. A good speech is the result of hard work, study and practice. What turns us away from the speaker is monotonous and uniform communication. We cannot significantly influence certain innate things, such as tone of voice, however, certain exercises and hard work can improve the tone of voice. The same is true for pronunciation. It is often said that public opinion is created by the media. Current affairs programmes should put the emphasis on people as individuals. When it comes to transmission of statements, the main idea, preparation, clarity and the performance itself are what is important. Politics and rhetoric have been closely related since ancient Greece, when political speech became the means for making decisions, laws and regulations. Each politician has to possess exceptionally good communication skills and use the right arguments and figures. He has to know how to get the interest of the audience as well as how to start and finish the speech. Politicians achieve their goals through persuasion and speaking skills. Special occasions are part of our everyday life, and formal addresses are thus an inevitable part of various ceremonies. These are short rhetoric forms. With motivational speeches, the speaker should spread enthusiasm, hope and positivity to set an example for his audience, the listeners. Preparations for meetings form an integral part of the 21th century education. Each meeting has its goal. Ideas are exchanged and evaluated, problems are solved, future businesses and plans are developed. With the development of humankind and technology, presentations became a separate form of rhetoric, often accompanied by visual material. Presentation skills also have to be perfected, just like public speeches, therefore many companies provide their employees with presentation skills training. Nelson Mandela as an example of the power of speech. He gave one of the most renowned speeches in history after being awarded the Nobel prize for peace.
