Aristotle

Greek philosopher and scientist, Aristotle, lived in the 4th century B.C. and is thought of as one of the most important figures from classical antiquity. Aristotle was probably the most famous member of Plato's Academy in Athens, whose writings would ultimately form the first comprehensive system of Western philosophy. His writings were not constrained to simply one field of inquiry but covered such various subjects as physics, biology, metaphysics,...

Written sometime in the 4th Century BC, Aristotle's "Rhetoric" is the definitive treatise on the art of persuasive public speaking. The art of oratorical persuasion was an essential skill for the successful politician during the days of ancient Greece and Aristotle's "Rhetoric" is considered one of the greatest works from antiquity on the subject. Like many of the surviving works attributable to Aristotle, "Rhetoric" was not intended for public dissemination,...

OUR next task is to study coming-to-be and passing-away. We are to distinguish the causes, and to state the definitions, of these processes considered in general, as changes predicable uniformly of all the things that come-to-be and pass-away by nature. Further, we are to study growth and 'alteration'. We must inquire what each of them is; and whether 'alteration' is to be, identified with coming-to-be, or whether to these different names there correspond...

THE science which has to do with nature clearly concerns itself for the most part with bodies and magnitudes and their properties and movements, but also with the principles of this sort of substance, as many as they may be. For of things constituted by nature some are bodies and magnitudes, some possess body and magnitude, and some are principles of things which possess these. Now a continuum is that which is divisible into parts always capable of...

The Ethics of Aristotle is one half of a single treatise of which his Politics is the other half. Both deal with one and the same subject. This subject is what Aristotle calls in one place the 'philosophy of human affairs;' but more frequently Political or Social Science. In the two works taken together we have their author's whole theory of human conduct or practical activity, that is, of all human activity which is not directed merely to knowledge...

Written in 350 BC, Aristotle's "De Anima" or "On the Soul" is not a work on spirituality, as the title would suggest, but rather a work that could be described as one of biopsychology, or a work on the subject of psychology from a biological perspective. Aristotle's exposition centers on the soul. Aristotle's soul however is not the same as the common modern spiritual conception of something distinct from the body that lives on past death. Rather...

Nicomachean Ethics focuses on the importance of habitually behaving virtuously and developing a virtuous character. Aristotle emphasized the importance of context to ethical behavior, and the ability of the virtuous person to recognize the best course of action. Aristotle argued that happiness and well being is the goal of life, and that a person's pursuit of such, rightly conceived, will result in virtuous conduct. "EVERY art and every inquiry, and...

One of the fundamental works of Western political thought, Aristotle's masterwork is the first systematic treatise on the science of politics. Aristotle in Politics examines the various options for governance and their respective values. A detailed and pragmatic approach to the subject, Politics provides much of the foundation for modern political thought. One of his central ideas is that "Man is a political animal," meaning that people can only...

All instruction given or received by way of argument proceeds from pre-existent knowledge. This becomes evident upon a survey of all the species of such instruction. The mathematical sciences and all other speculative disciplines are acquired in this way, and so are the two forms of dialectical reasoning, syllogistic and inductive; for each of these latter make use of old knowledge to impart new, the syllogism assuming an audience that accepts its...

The reasons for some animals being long-lived and others short-lived, and, in a word, causes of the length and brevity of life.
