Aristotle

Biography

Raphael portrays two of Greece's great philosophers as the focal point of his masterpiece The School of Athens. Aristotle has his hand pointing straight out as if he is declaring to Plato that truth is found right here around us. Aristotle was an excellent teacher who is considered to be the prince of philosophy and one of the world's most influential thinkers of all time. Aristotle was born in 384 B.C at Stragyra in Thrace, on the north coast of the Aegean Sea. This was fifteen years after the death of Socrates and three years after the founding of Plato's Academy. His father was the court physician and friend of King Amyntas of Macedonia. It is likely that Aristotle's great interest in biology and science, in general, was nurtured in his early childhood. At the age of seventeen, Aristotle moved to Athens and enrolled in Plato's Academy as a student of philosophy. He studied for over twenty years at the Academy until Plato died in 348 B.C. Throughout his time at the Academy, Aristotle became one of the top scientist and philosophers, and though he studied under Plato, he was not a Platonist. In fact, he would later criticize Plato and his various doctrines.

After the mourning of Plato's death had subsided, Speusippus seized power of the Academy. At this time Aristotle quickly left Athens and lived for a time in Assos and Mytilen where he was able to write, research, and teach. He did return, for a time, to Macedonia to tutor Philip's son Alexander at his request. By the age of forty-nine, Aristotle had traveled back to Athens to found a school. Many historians believe this is when Aristotle began the most productive period of his life. His school was named the Lyceum, named after the groves where Socrates went to think and which was the sacred domain of Apollo Lyceus. The Lyceum had a fine library, an extensive collection of maps, and a zoo where Aristotle preformed much of his zoological research. . The school was located close to a long covered walk called in the greek peripatos. Aristotle would take his students on this long covered walkway where he conducted much of his teaching as they strolled along pondering many philosophical questions. As a result of this method of teaching, the students of the Lyceum were commonly referred to as peripatetics. Aristotle was only in Athens for twelve years when it was necessary for him to leave for political reasons to save his life. In 322 B.C. Aristotle died and his library was passed on to his successor, Theophratus.

Aristotle is regarded as the first truly cosmopolitan thinker. He was interested in a plethora of subjects and gave significant contribution to many of them. He composed major studies of logic, ethics, and metaphysics. Today he is best renown for his work the Metaphysics and the Nichomachean Ethics. In addition to these major studies he also wrote on epistemology, physics, biology, meteorology, dynamics, mathematics, psychology, rhetoric, dialectics, aesthetics, politics, and philosophy. Choose any field of research and Aristotle probably studied it, select an area of human reason and he probably theorized on it. If all of his writings were published today they would fill fifty large volumes in print. Unfortunately, over the last two thousand years many of his writings have been lost. Only one fifth of his writings have endured time. What has been preserved are what many believe are Aristotle's lecture notes and notes of his students that were not meant to be printed. These rough notes have been edited in a cut paste fashion in order to try to make sense of Aristotle's profound thought.

Aristotle philosophy is a development of Plato's philosophy. Aristotle respected Plato but rejected the dualism that Plato passionately embraced and taught his pupils. Plato's primary reality of the unchanging world existed separately from the world of particular things. Aristotle believed he was able to avoid this ambiguous ideal of two worlds and still communicate all the necessary concepts that Plato did. Metaphysically, Aristotle believed that every living being, except God, is a composite of two factors called form and matter. In Aristotle's system of epistemology, he believes that the forms that Plato held unattainable actually exist as essential parts of the things that we asses through our senses. He believed that a human being is a holistic unit of both the body and soul.

Aristotle specialized in classifying the many different components in the universe: humans, animals, plants, inanimate objects, etc. His work Catergories was his flagship in the organization of the world. He believed that humans were certainly in a classification of their own, and that human beings could be divided up into three dimensions, or more specifically, three dimensional thinking. The first dimension is "productive thinking" and refers to man as a maker; the second is "practical thinking" and refers to man as a learner and knower. All of the books that Aristotle wrote can basically be divided into these three categories. For example his book on poetry would be in the category of productive thinking; ethics would be in the category of practical thinking; philosophy, science, and metaphysics would be in the category of theoretical thinking.

Aristotle can be credited with the creation of both the science and the philosophy of biology. His work in science involved the discovery of interconnections between characteristics of organisms. This led to the biological specialties of taxonomy and systematics. This evidenced that he was able to adapt his metaphysical and logical thought to that of the area of zoology. His application of thought to the experimentation makes him one of the founders of laboratory research.

Aristotle was the first to create the study of deductive inference. His theory of syllogism, simply put, is a discourse in which certain things having been stated, something else follows of necessity of doing so. Aristotle believed that the laws of logic apply to more than just human thinking. He believed that these laws of being allow the understanding of the logical structure of the world. The premise to his logical system is the law of noncontradiction. Aristotle states in his law that "It is impossible for the same attribute at once to belong and not belong to the same thing in the same relation." More simply would be that (B) can not be both (B) and non(b) at the same time in the same sense. This law cannot be proven but it must not be ignored. It is a universal core principle of human thinking. However, a caveat is necessary because the absence of a contradiction doesn't necessary guarantee truth.

The world is in a constant state of change. Aristotle
