Aristotle , a philosopher and scientist from ancient Greece , is considered one of the greatest intellectual figures in Western history. He was the author of a philosophical and scientific system that became the framework and vehicle for Christian scholasticism and medieval Islamic philosophy . Even after the intellectual revolutions of the Renaissance, Reformation, and Enlightenment, Aristotelian concepts remained embedded in Western thought.

Who was Aristotle?

He was one of the main philosophical figures of Greece and of antiquity. He left a cultural legacy on the disciplines of knowledge that have lived for more than two millennia.


Aristotle’s intellectual range was enormous, mainly in the field of natural sciences and arts , including biology, botany, chemistry, ethics, history , logic, metaphysics , rhetoric , philosophy of mind, philosophy of science , physics , poetics, political theory, psychology. and zoology.


He was the founder of formal logic , devising for it a finished system that for centuries was considered the sum of discipline; and he was a pioneer in the study of zoology . But his main role was as a philosopher . His writings in ethics and political theory, as well as in metaphysics and the philosophy of science continue to be studied, and his work remains a powerful current in contemporary philosophical debate.

Aristotle’s biography

Aristotle was born on the Chalkidian peninsula of Macedonia , in northern Greece . His father, Nicomacheus , was the physician to Amyntas III, who was King of Macedonia and grandfather of Alexander the Great . After the death of his father, Aristotle moved to Athens, where he joined the Academy of Plato , a place where he remained for 20 years as a student and colleague of Plato.

Some time after leaving Athens, he decided to return to the cradle of the civilization of Hellenic culture to found his own school, better known as the Lyceum, there .

In his last years of life he had managed to gather a large library , as well as a large number of followers, the Peripatetics , who were so named because the philosopher used to teach and discuss ideas with his students while walking.

It was during this last period that he wrote most of the works that remain to this day, including his famous Nicomachean Ethics . When he was 61 years old, Aristotle left Athens again when Alexander the Great’s death occurred in 323 BC. C. and traveled to Chalcis , where he died the following year of natural causes at 62 years of age.

Aristotle’s thought

Aristotle’s thought was based on different characteristics, which are:

His thoughts were based on syllogisms and for this reason he is considered the father of logic , as he was one of the first to study it and state its principles. The basis of logic is the syllogism through discourse . From certain signals, a necessary outcome is reached.

He believed in the principle of non-contradiction which holds that a proposition and its negation cannot be true at the same time nor can they have the same meaning. It is one of the basic laws of logic and allows more complex arguments.

Aristotle said that there were some apparently valid arguments but that they are not in reality, and for that reason he called them fallacies . For him the fallacies have the form of a syllogism .

For him, the essence can be identified with the substance of things and remains unchanged. He thought that the segmentation between the essential and the apparent can be applied to objects as well as to animals or people . He also thought that sciences were multiple and each one of them had its specific object.


Among his main contributions we can mention:

  • He founded a formal system of reasoning and that is why he is considered the father of logic .
  • He promoted the importance of premises .
  • He left great contributions in the field of politics , especially with the structure , operation and objective of the state and the city.
  • It ensured the importance of a ruler and a constitution to shape the lives of citizens.
  • Made contributions in the field of physiology and anatomy
  • He studied animal anatomy and compared it to the animal.
  • He developed a taxonomic or classification scheme on animals.
  • We inherited the learning process by association .

Arche of Aristotle

Aristotle’s arche was the substance, what the substratum meant, what gives us support . For him, what was opposed to the substance was the accident , which does not happen through oneself, but needs another being in order to occur. The relationship between the accident and the substance were at the same time linked.


Some of Aristotle’s writings also belong to this period, although most of them only survive in fragments. Aristotle wrote initially in dialogue form , and his early ideas show a strong Platonic influence .

  • His dialogue Eudemus reflects the Platonic vision of the soul as a prisoner of the body and as capable of a happier life only when the body has been left behind.
  • History of animals – and some little booklets about animals.
  • Small works on natural beings.
  • The first and last analytics.
  • On Philosophy.
  • Part of the Metaphysics books.
  • Part of the Policy.
  • On the Soul book III.
  • About the Interpretation.
  • Some short booklets on animals.
  • Rhetoric.

Aristotle phrases

  • The friendship is a soul inhabiting two bodies; a heart that dwells in two souls.
  • The ignorant affirms, the wise doubt and reflect.
  • The wise man does not say everything he thinks, but he always thinks everything he says.
  • I consider the one who conquers his desires more courageous than the one who conquers his enemies, since the hardest victory is the victory over oneself.
  • Anyone can get angry , that is something very simple. But getting mad at the right person, at the right degree, at the right time, for the right purpose, and in the right way. That is certainly not that simple.
