The Theory of the Ideas and Plato’s Ontology

Plato’s Theaetetus starts off with Euclid of Megara by speaking with his friend Terpsion about a dialogue he has between Socrates and Theaetetus. He says, that the dialogue was from when Theaetetus was young. Euclid of Megara’s conversation with Terpsion acts as the structure for the dialogue itself. The other participants of the dialogue are Socrates, Theodorus, and Theaetetus. The question that the participants are asking is “what is knowledge?” Theaetetus gives four definitions to the question “what is knowledge?” The first being that knowledge is arts and sciences, the second being knowledge is sense-perception, the third that knowledge is true judgment, and the fourth being knowledge is true judgment with an account. But Socrates was

Plato separates reality into two spheres: one of appearance, which is a material world, and one of reality. Plato believes “in a transcendent world of eternal and absolute beings, corresponding to every kind of thing there is, and causing in particular things their essential

Plato’s idea that there was a perfect world of ideas affected this pieces subject and the

According to this allegory, which is related to Plato's Theory of Forms", the "Forms" (or Ideas"), own the highest and most fundamental kind of reality, and not the material world of change known to us through sensation. Real knowledge composes of knowledge of the Forms only. It is an attempt to explain the philosopher's place in society and to attempt to impart knowledge to the "prisoners".

Plato is remembered as one of the worlds best known philosophers who along with his writings are widely studied. Plato was a student of the great Greek philosopher Socrates and later went on to be the teacher of Aristotle. Plato’s writings such as “The Republic”, “Apology” and “Symposium” reveal a great amount of insight on what was central to his worldview. He was a true philosopher as he was constantly searching for wisdom and believed questioning every aspect of life would lead him to the knowledge he sought. He was disgusted with the common occurrence of Greeks not thinking for themselves but simply accepting the popular opinion also known as doxa. Plato believed that we ought to search for and meditate on the ideal versions of beauty, justice, wisdom, and other concepts which he referred to as the forms. His hostility towards doxa, theory of the forms, and perspective on reality were the central ideas that shaped Plato’s worldview and led him to be the great philosopher who is still revered today.

“If the truth of all things always existed in the soul, then the soul is immortal” (The Philosophical Journey 89). This states that since the soul has all knowledge integrated, one recollects this knowledge through situations in an individual’s life and use one’s reasoning. With the dialogues of the Meno and Phaedo, Plato discusses the ideas of recollection and immortality of the soul in general. As well, the Republic, through the three different situations shown, Plato shows the ideas of the forms and what is real and what is not.

Plato's theory of forms, also called his theory of ideas, states that there is another world, separate from the material world that we live in called the "eternal world of forms". This world, to Plato, is more real than the one we live in. His theory is shown in his Allegory of the Cave (from The Republic, Book VII), where the prisoners only live in what they think is a real world, but really it is a shadow of reality. According to Plato, to the prisoners in the allegory and to humanity in the material world "truth would be literally nothing but shadows" and he believes us to be as ignorant as the people in the cave. Plato followed the belief that in order for something to be real it has to be permanent, and as everything in the world we

Plato, in addition to being a philosopher, wrestled at the Olympic level, is one of the classical Greek authors, mathematicians and the founder of The Academy, the first higher learning institute in the west. In short, Plato is one of the great thinkers in history and his contributions to philosophy, ethics and politics are many and varied. One of Plato’s main philosophical ideas is based on the idea that the world

In his essay, “The Allegory of the Cave,” Plato, argues his idea of how to distinguish the reality and truth from that which is a falsehood. Most essentially, he finds it as important to enlighten others that may remain in that

This paper discussed The Allegory of The Cave in Plato's Republic, and tries to unfold the messages Plato wishes to convey with regard to his conception of reality, knowledge and education.

Plato, arguably one of the most famous philosophers in history is known for his dialogues and theory of Forms. The theory of Forms argues that ideas (non-physical forms) are more real than tangible objects or what our senses perceive. According to Plato, there is the visible realm and intelligible realm. Reality could be divided into three different levels; the level of appearances, the real level, and the ideal level which he explains through the analogy of the ‘Divided Line’ in The Republic.

universal truths and pass it on to those who cannot see it. To Plato the above is his

“Everything which exist in this world and all things that we see around us are not as they appear to us” this is the core idea behind plato’s theory of forms.From this idea only he moves towards explaining his world of forms or ideas.

Plato argued that true knowledge was not obtained through the knowledge of the physical world around us, but from these unchanging ideas. Plato’s theory of knowledge is well explained through his discussion of the Divided Line; a line divided into two unequal parts. One section represents the visible order and the other intelligible order, relating to opinion and knowledge, respectively. The stages of cognition flow upwards: imagining, belief, thinking, and intelligence. The visible, changing world of opinion begins with the awareness of images through perception. Awareness of images can include

Plato was interested in how we can apply a single word or concept to many words or things. For example how can the word house be used for all the individual dwellings that are houses? Plato answered that various things can be called by the same name because they have something in common. He called this common factor the thing’s form or idea. Plato insisted that the forms differ greatly from the ordinary things that we see around us. Ordinary things change but their forms do not. A particular triangle may be altered in size or shape but the form of a triangle can never change. Plato concluded that forms exist neither in space or time. They can be known not only by the intellect but also by the senses. Because of their stability and perfection, the forms have greater reality than ordinary objects observed by the senses. Thus true knowledge is knowledge of the forms.
