between 334 and 323 BC." They encompass both his 'scientific' writings (metaphysics, physics, biology, meteorology, and astronomy, as well as logic and argument) the 'non-scientific' works (poetry, oratory, ethics, and politics), and "major elements in traditional Greek and Roman education". Writers of textbooks also use writing to teach and there are numerous instructional guides to writing itself. For example, many people will find it necessary to make a speech "in the service of your company, church, civic club, political party, or other organization" and so, instructional writers have produced texts and guides for speechmaking. Tell a story Many writers use their skill to tell the story of their people, community or cultural tradition, especially one with a personal significance. Examples include Shmuel Yosef Agnon; Miguel Ángel Asturias; Doris Lessing; Toni Morrison; Isaac Bashevis Singer; and Patrick White. Writers such as Mario Vargas Llosa, Herta Müller, and Erich Maria Remarque write about the effect of conflict, dispossession and war. Seek a lover Writers use prose, poetry, and letters as part of courtship rituals. Edmond Rostand's play Cyrano de Bergerac, written in verse, is about both the power of love and the power of the self-doubting writer/hero's writing talent. Authorship Pen names Writers sometimes use a pseudonym, otherwise known as a pen name or "nom de plume". The reasons they do this include to separate their writing from other work (or other types of writing) for which they are known; to enhance the possibility of publication by reducing prejudice (such as against women writers or writers of a particular race); to reduce personal risk (such as political risks from individuals, groups or states that disagree with them); or to make their name better suit another language. Examples of well-known writers who used a pen name include: George Eliot (1819–1880), whose real name was Mary Anne (or Marian) Evans; George Orwell (1903–1950), whose real name was Eric Blair; George Sand (1804–1876), whose real name was Lucile Aurore Dupin; Dr. Seuss (1904–1991), whose real name was Theodor Seuss Geisel; Stendhal (1783–1842), whose real name was Marie-Henri Beyle; and Mark Twain (1835–1910), whose real name was Samuel Langhorne Clemens. Apart from the large numbers of works attributable only to "Anonymous", there are a large number of writers who were once known and are now unknown. Efforts are made to find and re-publish these writers' works. One example is the publication of books like Japan As
