Note | Philosophy of Aristotle

Contributor to Every Fields of the Human Knowledge

Aristotle is the greatest philosophers, and one of the greatest polymaths in the human history. He researched on all of knowledge from today’s natural science to social science and humanities, for example biology, natural history, physics, metaphysics, ethics, aesthetics, logic, rhetoric, psychology and politics. And his noteworthy achievement is the inquires on the system of knowledge, being, activity and logic.

Aristotle collected and organized theories of Greek philosophy till Socrates and Plato, and give back philosophy to Presocratic natural study, also he adopted Socratic ethical thought and modified Plato’s philosophy.

Metaphysics

Aristotle was a most eminent pupil of Plato, and he criticized Plato’s philosophy and critically succeed it. Aristotle inspected the defect of Plato’s theory of forms and modified it. He turned around Plato’s idealistic view and presented his realistic view, also grasp the natural things and world. And he planned to moderate Presocratic natural philosophy and Plato’s theory of ideas.

On Plato’s theory of forms, we can’t confirm existence of the world of idea, and on the theory of forms, the connection between form and things is unclear. And the theory of forms apply only productive and artificial things (things can exist by techne), can’t apply natural things (things can exist by physis). Aristotle inquired the changes and transformations of things, also tried to construct a theory covers natural things and the nature.

Different to Plato’s idealistic and abstract theory of forms, Aristotle thought each things and existences should be grasped concretely. The four causes theory describe all ousia (independent being or substance, or subject of a sentence) are made by a combination of eidos, hyle, dynamis and entelecheia

Aristotle thought all things have aspects of eidos (form or essence) and hyle (matter, stuff or existence). Eidos is formal cause of things and hyle is material cause of things.

Plato thought a connection between a thing (matter) and an idea (eidos) is accidental and external. But Aristotle thought hyle includes eidos as a potentially. The potentiality is named dynamis (agent, potentiality and efficient). Dynamis is moving cause of things, and the state is realized by it is named entelecheia (actuality, end or purpose).

All things are understood, have dynamis and entelecheia, and are relative between them. A tree is a purpose of a seed, also is potentiality of a material wood. A material wood is an actuality of a tree, also a potentiality of a desk. A desk is an actuality of a wood, also an agent of writing or working.

By Aristotle’s view is biological, and all things are moving. All things or existences are in the teleological moving to realize potentiality is in each of things. And this moving of things is caused by the power of gods. For Aristotle, to see this moving or changing is to feel gods’ grace. So Aristotle called his metaphysics “theology”.

Ethics

Aristotle’s teleological view to the nature relates to his practical philosophy or ethics. He thinks good men can be wise and virtuous only by experiences of praxis, like the moving of things. He thought moral and ethics can’t teach for children, only adult can study them.

Ethics treats the aspect of praxis (practice or action) in which the internal function itself of beings which works and realizes. In a scene of praxis, the problem is human nature and the virtue. On the other hand, virtue is not opposite to the nature, but is not given by the nature. Men can be virtuous to perceive the nature, and to complete the human nature by habits. Ethics is a point joins the nature and techne. Virtue is a kind of habit made by the human nature, become the second nature, it means virtue is ethos (characteristics, habit) of human.

The human proper property different to other creatures and things is logos (discretion or reason). Aristotle thought happiness is realized when logos in a spirit performs on a scene of praxis.

And the supreme good state by Aristotle, is theoria (theory), the stable state such as perception, reflection or meditation to see and appreciate changing of things and praxis by logos.

Problems of Aristotlian Philosophy

Aristotle made a great achievement and contribution in philosophy, but he remained many problems on philosophy.

He organized all theories of Greek philosophy, and constructed a huge system of philosophy. But he made philosophy complexed. Philosophy after Aristotle to the modern philosophy, became interpretation and argument about Aristotle’s philosophy. Especially the medieval scholasticism solely adapted and harmonized Christian theology and Aristotle’s philosophy. The problem of universals was the argument about which is important essentia (Aristotle’s eidos) or existentia (hyle) for a long time.

Plato’s theory of ideas is a total universal monism system, can explain being, changing, moral, beauty and politics. Aristotle made a total system of philosophy and science, but he divided science and philosophy into many subjects and branches. And there are different principles is in each subjects and branches, he thought.

Also his thinking of the divide of the static principle of metaphysics and the world of theoria from the biological changeable world left many problems in philosophy.

Note | Plato’s Theory of Ideas

Plato

Plato is the first philosopher set up philosophy as a total principle and a total human study. He was s pupil and the most influential successor to Socrates. Plato theorized Socrates’ act of life, his pursuit for virtue and truth, thought and questions, then established a philosophical principale theory (as a love of wisdom) for the first time.

And Plato, in his dialogues, treated many philosophical topics such as being, virtue, wisdom, beauty and politics which last until now.

The Theory of Ideas

Plato’s famous and important key concept is the theory of Ideas, also called the theory of forms, the doctrine of ideas.

The word origin of idea is “idein”, “to see” in ancient grec. The meaning of word idea in is “form or appearance is seen”. Also Aristotle’s eidos (form) has same origin and similar meaning. (But their actual meaning is different.) Idea is not unclear, airy, fluid or rough concept. It’s an abstract and unreal but solid and absolute form in the heaven, of which things and abstract concepts have. Plato’s idea is the original ideal form of each of things. Ideas belong to each species of things and concepts.

For example square. A square on a paper written by a man isn’t perfect, the lines are not completely straight and same length, and have thickness, the angles are not completely right angle, and the inner space is not completely closed or the lines stick out slightly. But we recognize it as a square. Like this, Plato thinks a square on a paper shares the idea of square. And Plato thinks each things (such as tree, desk and horse) and abstract concepts (such as good, love and beauty) have their ideas. Also things are in existence since they are provided, shared out by their idea.

Plato’s thinking is curious for us, but it supposed to have the aim to criticize the realistic view, materialism and decadence of Athens’ democracy, Presocratic philosophers and sophists. Their thoughts are things to leave to take its own course. Socrates and Plato thought the cause of the decadence is especially realism, practicalism and relativism of sophists.

Until Socrates, Presocratic philosophers researched the rule and system in the nature and they think there’s truth in the nature. Platon made the view to world reversed. Plato’s theory of ideas advocate the value of things and politics as they should be. The thought of Plato is order of spirit or mind makes a world. So the truth is in a mind of each persons.

Universal Principle and Problems of Platonism

The property of Ideas of each things are eternal and unchangeable. So an idea is identical and universal for everyone. By Plato’s thought, all wise men and men want to live good pursue and want the idea of good. And the idea of good is one and eternal, so they can understand mutually and have the universal principle of good. The theory of ideas shows possibility of mutual understanding and universal principle.

Plato’s philosophical thought by the theory of ideas called Platonism. Platonism teaches us the value of pursuit truth, virtue, wisdom and beauty. It’s a kind of idealism, positivism and optimism. There are ideal and perfect states of things in the world of idea, the model of the real world, and we can pursuit them and we should do it. A typical influence by Platonism is seen on education. Children must not be led nature take its own course, should be educated to become a good person.

On the other hand, there are any problems of Platonism. Platonism thinks the truth or the idea of good is one. So it can’t accept diversity of values. And Platonism bring about logical optimism, excessive rationalism and totalitarianism.

Platonism thinks there’s the world of ideas beyond the real world far in the distance, and offers pursuit for the world of ideas and truth, but we can’t never reach and grasp the true, ideal and perfect states of things. Platonism is an idealism, so it never fulfil the thought perfectly. And it regard reality or the real world is inferior to the world of ideas, the real world is provisional and temporary world. So Platonism possibly result in nihilism and cynicism.

Binomial opposition of ideas and reality of Platonism have been influenced on the Western thought and culture for good and bad.

Conclusion

Plato theorized Socrates’ philosophy, established the philosophy as love of wisdom in earnest which became the tradition of philosophy, and set up the first total philosophical principle unit ontology, ethics, beauty, politics and so on. Theory of ideas includes and units ontology, ethics, aesthetics and political thought. The theory of ideas and Platonism are a strong and influential ways of thinking.

Platonism have been influenced on the Western thought and culture. But it concealed the value of diversity, and regarded earthly world and life inferior and worthless.

Note | Philosophy of Socrates

The Man Set Up Philosophy as A Human Inquisition

Socrates is a philosopher who set up the philosophy as a human inquisition and a moral science for the first time. And it’s said that he invented the word philosophy. So that he is called “the father of philosophy”. And he is the creator of today’s ethics.

Philosophers before Socrates, such as Thales, Anaximander, Pythagoras, Heraclitus and Democritus utterly pursued and learned about rules and causes of the nature, the world or the universe. But the huge impact of Socrates changed the language game of philosophy. So philosophers before Socrates are named “Vorsokratiker (Presocratics)”.

The Socratic Problem

Socrates wrote nothing. He thought verbal words are only livid, written text is dead words. To know Socrates thought, it can be only from describes by authors of the same age. The representative authors are Xenophon, Aristophanes and Plato. Despite, these three descriptions about Socrates are utterly different. Xenophon describes Socrates as an ideal and sincere but strict teacher led truth and virtue, also told boring moral by common knowledge. Aristophanes’ character of Socrates is bold, unreliable and stupid sophist told the way of debate, took money for a charge, also researched natural studies. Plato’s Socrates is a cynical and ironic thinker always told paradoxical sayings, also have a god-like genius of thinking and debate.

By the philosophical contribution, I’ll comment on Plato’s Socrates.

Opposition to Sophists

The first half of Socrates’ life isn’t quite known. Socrates served in the military, went to the war three times. And he studied mathematics, astronomy and natural philosophy under Archelaus. But he soon noticed these study not useful for human understanding.

It’s said that in his forties, he began to tell and argue his philosophy at agora, and to dispute with the sophists. The sophist are a school philosophy of professional teachers told various knowledge and skills, especially rhetoric to win opponents and to attract audiences in an assembly or a court. They thought language is a tool and language itself has a sense and a truth, it’s right to win a debate by sophistry. By the technique of rhetoric, we can insist yes or no, good or bad in all subjects, they thought. And their thought is relativism. Protagoras’ famous saying “Man is the measure of all things,” stands for human thinking and sense are criterion of value of all things, and value of things are different each of men.

On the contrary Socrates insisted it should be extracted the truth and the value from things themselves. By using words and logic we must take out contradictions, demonstrate intuitions and prove the truth.

The Socratic Method : Elenchos (or Maieutike)

A day of late in life, Socrates’ friend Chaerephon received the answer that “no one was wiser than Socrates” by the Oracle at Delphi. Socrates felt the answer is not correct and thought “I know nothing expect the fact of my own ignorance”, and he decided to certify it. So Socrates visited and argued with politicians, poets (playwrights) and artisans (they were considered most honourable in Greek at that time).

Socrates argued about wisdom, temperance, courage and justice with notables. The argument is processed by the Socratic Questioning, a method of questioning, a question responses an interlocutor’s question to redefine his question. For example, an interlocutor presented a definition, Socrates told a further premise and the interlocutor approved of the premise, and Socrates further discussed and proved the definition and the premise are a contradiction, then Socrates insisted on the interlocutor’s definition is false or non-sense and the converse is true. This Socrates’ method indicate new consideration and refined definition, also interlocutors can’t say anything further and must recognize their ignorance and blunder.

This method of negatively aggressive questioning is named Socratic Method (Elenchos), also is named Maieutike (the way of midwife), . Because Socrates found a new knowledge or perception went through a hardships. And Socrates developed the dialectic which is made progress by Plato, Aristotle, Kant and Hegel.

“Knowing I Know Nothing” (The Socratic Ignorance)

By the arguments, Socrates recognized personages supposed to be wise, don’t know the truth and virtue, and only he know “I know that I know nothing”, so Socrates is wiser than others.

The Socratic Ignorance is a criticism to practical knowledge and vanity. Personages in Athens knew only separated practical knowledge. They didn’t know the importance of truth and virtue, the basis of things.

Some scholars think “knowing I know nothing” is a kind of knowledge and a self-contradiction. The true meaning of the Socratic Ignorance might be an “I understand just the importance of truth and virtue”.

The meaning of Socratic Ignorance is not only a nihilism or a cynicism. He found the importance of truth, virtue and moral issues. It’s a starting point to pursuit truth, virtue, humane study and ethics.

Why Socrates accepted the death penalty ?

Socrates’ emphasis on good spirit and virtue, his dialectic method look strange and abnormal for Athens citizens at that time. (Some researchers say Socrates extremely pushed forward very conservative and common thoughts such as faith gods, temperance and a proverb “know thyself”.) Socrates’ point of view and his method of debate is shocking for the citizens. So he was blamed, hated and feared by many people. Then Socrates was accused by a fake crime of atheism or faith in Damon by malicious men.

In the trial, Socrates testified against him and bitterly attacked accusers by his philosophical faith and principle. He made jury members angry more than necessary, and unfortunately received a sentence of death.

Socrates’ policy is pursuit of virtue, wisdom and truth, and inseparability of knowledge and action. Opposition to the law and the judgement of the nation is different with his policy. It’s an injustice. So he accompanied the law of Athens, accepted the death penalty, and took a cup of hemlock to follow his particular pragmatic philosophic view. He devoted his life to his philosophy and will to virtue. Therefore his act and thought remain permanently and they turned the meaning of philosophy.

Criticism to Socrates

Socrates is a martyr of philosophy. By his saintly activity, Socrates is worshiped as a saint equal to Jesus Christ and Buddha. But Socrates is criticized by many thinkers from the later modern era.

Especially Nietzsche severely accused the activity and the philosophy of Socrates. He really dislike Socrate’s belief of processes of thinking by dialectic must lead the truth, thought it as a very strange belief. What’s more Nietzsche said it’s further wrong Socrates took a cup of hemlock by himself to follow the validity of his logic. Socrates is the prototype of the theoretical optimist and the originator of the intellectualism about knowledge and logic.

By the modern and contemporary philosophers generally regard Socrates’ philosophy as an intellectualism, an anthropocentrism and a centrism of virtue, wisdom and reason. Socrates concealed the value of lively nature and the true nature of human in the nature are pursued by the Presocratics, and first divided philosophy into the human inquisition (today’s meaning of philosophy) and the natural science.

Conclusion

Socrates is a revolutionist of philosophy and a true activist of “philosophia”. His life and activity made a huge impact on philosophy and ethics. He launched the second birth of philosophy, and philosophy became a human inquisition and a moral science. His philosophy made huge impact on the Western culture and studies.

But he made an end to natural philosophy by the Presocratics, concealed the value of lively nature and the human nature in the nature pursued by them, and divided philosophy into the human inquisition and the natural science.
