540-412: The nous , wherein is contained the infinite store of ideas. The world-soul , the copy of the nous , is generated by and contained in it, as the nous is in the One, and, by informing matter in itself nonexistent, constitutes bodies whose existence is contained in the world-soul.

He also thinks that the soul is the bearer of moral properties (i.e., when I am virtuous, it is my soul that is virtuous as opposed to, say, my body).

From this geometry he derived a new cosmology with

1080-559: The beautiful is opposite of the ugly, they are two." [Glaucon:] "Of course." "And since they are two, each is one?" "I grant that also." "And the same account is true of the just and unjust, the good and the bad, and all the forms. Each of them is itself one, but because they manifest themselves everywhere in association with actions, bodies, and one another, each of them appears to be many." "That's right." "So, I draw this distinction: On one side are those you just now called lovers of sights, lovers of crafts, and practical people; on

1215-409: The being and knowing of all other Forms is contingent. Conceptions derived from the impressions of sense can never give us the knowledge of true being, i.e., of the forms.

1305-968: The critical realism and metaphysics of Nicolai Hartmann . In contemporary philosophy, most Platonists trace their ideas to Gottlob Frege 's influential paper "Thought", which argues for Platonism with respect to propositions, and his influential book, The Foundations of Arithmetic , which argues for Platonism with respect to numbers and is a seminal text of the logicist project. Contemporary analytic philosophers who espoused Platonism in metaphysics include Bertrand Russell , Alonzo Church , Kurt Gödel , W. V. O. Quine , David Kaplan , Saul Kripke , Edward Zalta and Peter van Inwagen . Iris Murdoch espoused Platonism in moral philosophy in her 1970 book The Sovereignty of Good .

In contemporary Continental philosophy , Edmund Husserl 's arguments against psychologism are believed to derive from

1350-404: The existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object. In a narrower sense, the term might indicate the doctrine of Platonic realism ,

1440-503: The forms, the eternal, unchangeable, perfect types, of which particular objects of moral and responsible sense are imperfect copies. The multitude of objects of sense, being involved in perpetual change, are thereby deprived of all genuine existence. The number of the forms is defined by the number of universal concepts which can be derived from the particular objects of sense. The following excerpt may be representative of Plato's middle period metaphysics and epistemology: [Socrates:] "Since

1530-550: The other side are those we are now arguing about and whom one would alone call philosophers." "How do you mean?" "The lovers of sights and sounds like beautiful sounds, colors, shapes, and everything fashioned out of them, but their thought is unable to see and embrace the nature of the beautiful itself." "That's for sure." "In fact, there are very few people who would be able to reach the beautiful itself and see it by itself. Isn't that so?" "Certainly." "What about someone who believes in beautiful things, but doesn't believe in

1575-452: The reception of Plato in early modern Europe was how to deal with the same-sex elements of his corpus. Christoplatonism is a term used to refer to a dualism opined by Plato, which holds spirit is good but matter is evil, which influenced some Christian churches , though the Bible's teaching directly contradicts this philosophy and thus it receives constant criticism from many teachers in

1620-466: The soul moves things by means of its thoughts, as one scholar puts it, and accordingly, the soul is both a mover (i.e., the principle of life, where life is conceived of as self-motion ) and a thinker.

Plato delivered his lectures at

1665-481: The soul? That absolutely is. The Phaedo most famously caused problems to scholars who were trying to make sense of this aspect of Plato's theory of the soul, such as Broadie and Dorothea Frede. More-recent scholarship has overturned this accusation arguing that part of the novelty of Plato's theory of the soul is that it was the first to unite the different features and powers of the soul that became commonplace in later ancient and medieval philosophy. For Plato,

1710-504: The system in conscious opposition to Christianity —even as many influential early Christian writers took inspiration from it in their conceptions of monotheistic theology. The Platonic Academy was re-established during this period; its most renowned head was Proclus (died 485), a celebrated commentator on Plato's writings. The academy persisted until Roman emperor Justinian closed it in 529. Platonism has had some influence on Christianity through Clement of Alexandria and Origen , and

1755-439: The tenets of Christianity and Islam that are today classified as 'orthodox' teachings, but also the gnostic or esoteric 'heterodox' traditions of these religions that circulated in the ancient world, such as the former major world religion Manichaeism , Mandaeism , and Hermeticism .

1800-566: The theory of a Great Earth, which states that the Earth is a maximal sphere in a cyclical space and its surface therefore a total plane , the equator plane of the Cosmos . The (total) plane, as well as the straight line and space as a whole, is flat, without curvature yet closed, running back on itself. Barthel considered this his most important theory, even the most significant thought of the century , as he writes in his autobiography. While some of his academic colleagues stated that Barthel's theory

1845-420: The theory of the Forms, on the one hand, and, on the other hand, the doctrine of the immortality of the soul. Indeed, Plato was the first person in the history of philosophy to believe that the soul was both the source of life and the mind. In Plato's dialogues, the soul plays many disparate roles. Among other things, Plato believes that the soul is what gives life to the body (which was articulated most of all in
