Aristotle

Aristotle (c. 384 B.C. to 322 B.C.) was an Ancient Greek philosopher and scientist who is still considered one of the greatest thinkers in politics, psychology and ethics. When Aristotle turned 17, he enrolled in Plato’s Academy. In 338, he began tutoring Alexander the Great. In 335, Aristotle founded his own school, the Lyceum, in Athens, where he spent most of the rest of his life studying, teaching and writing. Some of his most notable works include Nichomachean Ethics, Politics, Metaphysics, Poetics and Prior Analytics.

Aristotle’s Books Aristotle wrote an estimated 200 works, most in the form of notes and manuscript drafts touching on reasoning, rhetoric, politics, ethics, science and psychology. They consist of dialogues, records of scientific observations and systematic works. His student Theophrastus reportedly looked after Aristotle’s writings and later passed them to his own student Neleus, who stored them in a vault to protect them from moisture until they were taken to Rome and used by scholars there. Of Aristotle’s estimated 200 works, only 31 are still in circulation. Most date to Aristotle’s time at the Lyceum.

'Poetics'

Poetics is a scientific study of writing and poetry where Aristotle observes, analyzes and defines mostly tragedy and epic poetry. Compared to philosophy, which presents ideas, poetry is an imitative use of language, rhythm and harmony that represents objects and events in the world, Aristotle posited. His book explores the foundation of storymaking, including character development, plot and storyline.

'Politics'

In Politics, Aristotle examined human behavior in the context of society and government. Aristotle believed the purpose of government was make it possible for citizens to achieve virtue and happiness. Intended to help guide statesmen and rulers, Politics explores, among other themes, how and why cities come into being; the roles of citizens and politicians; wealth and the class system; the purpose of the political system; types of governments and democracies; and the roles of slavery and women in the household and society.

'Metaphysics'

In his book Metaphysics, Aristotle clarified the distinction between matter and form. To Aristotle, matter was the physical substance of things, while form was the unique nature of a thing that gave it its identity.

'Nicomachean Ethics' and 'Eudemian Ethics'

In Nichomachean Ethics, which is believed to have been named in tribute to Aristotle’s son, Nicomachus, Aristotle prescribed a moral code of conduct for what he called “good living.” He asserted that good living to some degree defied the more restrictive laws of logic, since the real world poses circumstances that can present a conflict of personal values. That said, it was up to the individual to reason cautiously while developing his or her own judgment. Eudemian Ethics is another of Aristotle’s major treatises on the behavior and judgment that constitute “good living.”

On happiness: In his treatises on ethics, Aristotle aimed to discover the best way to live life and give it meaning — “the supreme good for man,” in his words — which he determined was the pursuit of happiness. Our happiness is not a state but but an activity, and it’s determined by our ability to live a life that enables us to use and develop our reason. While bad luck can affect happiness, a truly happy person, he believed, learns to cultivate habits and behaviors that help him (or her) to keep bad luck in perspective.

The golden mean: Aristotle also defined what he called the “golden mean.” Living a moral life, Aristotle believed, was the ultimate goal. Doing so means approaching every ethical dilemma by finding a mean between living to excess and living deficiently, taking into account an individual’s needs and circumstances.

'Prior Analytics'

In Prior Analytics, Aristotle explains the syllogism as “a discourse in which, certain things having been supposed, something different from the things supposed results of necessity because these things are so.” Aristotle defined the main components of reasoning in terms of inclusive and exclusive relationships. These sorts of relationships were visually grafted in the future through the use of Venn diagrams.

'Rhetoric'

In Rhetoric, Aristotle observes and analyzes public speaking with scientific rigor in order to teach readers how to be more effective speakers. Aristotle believed rhetoric was essential in politics and law and helped defend truth and justice. Good rhetoric, Aristotle believed, could educate people and encourage them to consider both sides of a debate. Aristotle’s work explored how to construct an argument and maximize its effect, as well as fallacious reasoning to avoid 

Other Works on Logic
Besides Prior Analytics, Aristotle’s other major writings on logic include Categories, On Interpretation and Posterior Analytics. In these works, Aristotle discusses his system for reasoning and for developing sound arguments.

Works on Science
Aristotle composed works on astronomy, including On the Heavens, and earth sciences, including Meteorology. By meteorology, Aristotle didn’t simply mean the study of weather. His more expansive definition of meteorology included “all the affectations we may call common to air and water, and the kinds and parts of the earth and the affectations of its parts.” In Meteorology, Aristotle identified the water cycle and discussed topics ranging from natural disasters to astrological events. Although many of his views on the Earth were controversial at the time, they were re-adopted and popularized during the late Middle Ages.
