“Earthly knowledge is but shadow. Everything in the world is a shadow of its ideal form in the world of ideas. The allegory of the cave, in which knowledge of the world is limited to mere shadows of reality and truth is used by plato to explain his idea of a world of perfect form or ideas.”
My Notes
The real world is the world of ideas which contains the ideal form of everything we are born with the concept of this ideal form in the mind. The illusory world in which we live, the world of the census, contains imperfect copies of the ideal form. We recognize things in the world, such as dogs because we recognize they are in perfect copy of the concept in our minds. Everything in the world is a shadow of its ideal form in the world of ideas. World of ideas: Reasoning brings Plato to only one conclusion that there must be a world of ideas or forms which is totally separate from the material world. It is there that the idea of the perfect triangle along with the idea of perfect bed or a dog exists. He concludes that human senses cannot perceive this place directly. It is only it is perceptible to us through reason. Play to even goes on to state that this realm of ideas is reality and that the world around us is merely modeled upon it. Plato argues that our concepts of ideal form must be innate, even if we are not aware of this, he believes that human beings are divided into 2 parts. The body and the soul, our bodies, possess the senses through which we are able to perceive the material world, which the soul possesses the reason with which we can receive the realm of ideas. Plato concluded that our soul, which is immortal and eternal, must have inhabited the world of ideas before our birth and still yearns to return to the realm after our death. So when we see variation of the ideas in the world with our senses, we recognize them as a sort of recollection, recalling the innate memories of these ideas requires reason- an attribute of the soul.
