베나세라프의 수의 비고유성 논증은 플라톤주의에 대한 강력한 반박들 중의 하나다. 이에 대한 플라톤주의 진영에서의 대응은 현재까지 네 가지 정도가 있었다. 라이트와 헤일로 대표되는 신프레게주의, 샤피로의 ante rem 구조주의, 밸러거의 혈기왕성한 플라톤주의, 그리고 잴타의 원리화된 플라톤주의에서의 대응들이 그것들이다. 이 네 가지 대응들 중 잴타의 원리화된 플라톤주의는 진정한 플라톤주의로 간주되기 매우 힘들며, 신프레게주의는 수의 비고유성 문제해결에 심각한 어려움을 갖고 있다. 한편 수의 비고유성 문제를 어느 정도 극복하고 있는 듯이 보이는 샤피로와 밸러거의 견해들 중, 밸러거의 견해는 인식과 지칭의 문제와 관련하여 심각한 난관에 봉착해 있다. 따라서 현재까지 제시된 이론의 상태에서는 샤피로의 견해가 수의 비고유성 문제를 인식의 문제와 함께 가장 잘 해결하고 있는 것으로 평가될 수 있다.

The most difficult problem for mathematical Platonism is the epistemological problem raised by Paul Benacerraf and Hartley Field. Recently, Mark Balaguer argued that his version of mathematical Platonism, Full Blooded Plantonism (FBP), can solve the epistemological problem. In this paper, I show that there are serious problems with Balaguer's argument. First, I analyse Balaguer's argument and reveal a formal defect in his argument. Then I raise an objection based on an analogical argument. Finally, I disarm some potential moves from Balaguer.

is Plato's last great philosophical work. 'Nocturnal Council' is located in the end of this work. Many scholars interpret 'Nocturnal Council' into opposite directions. According to one interpretation, this Council is a kind of an addition to supplement the philosophical elements. So this is Plato's 'after-thought'. But another interpretation is that 'Nocturnal Council' is a climax in Plato's political thought. Plato didn't abandon the theory of Idea in . In this respect, we find a coherence between and . Finally, a vague position of 'Nocturnal Council' in remains an opposite interpretations each other.

Plato said that our cosmos was created from the union of nous and $anank{\bar{e}}$ in Timaeus. In addition to this, 'the third kind', namely $ch{\bar{o}}ra$, exists already with genesis before the birth of the cosmos. Plato explains this $ch{\bar{o}}ra$ with several metaphors. That is, 'receptacle', 'mother', 'gold', 'space', 'place' etc. From Aristotle to contemporary scholars, generally three types of interpretations are presented. First, $ch{\bar{o}}ra$ is a kind of a 'void.' Secondly, $ch{\bar{o}}ra$ is Aristotle's $prot{\bar{e}}$ $hyl{\bar{e}}$. Thirdly, $ch{\bar{o}}ra$ has two aspects of space and matter. I will accept the third opinion. Plato's $ch{\bar{o}}ra$ has both a spatial aspect and material aspect. $Ch{\bar{o}}ra$ is a place that accommodates all sensible things in itself. On the other hand, $ch{\bar{o}}ra$ seems to be a mother who nourishes sensible things like a child. In this, Plato lacks a logical consistency. The research of $ch{\bar{o}}ra$ can not deviate from the limits of $eik{\bar{o}}s$ logos.

Plato's political thought is developed in , and . He hopes 'justifiable state' that all citizens can get happiness. He suggests the plan of the ideal state. And the most important element in this ideal state is philosopher-king. His metaphysics, psychology and education theory are melted in philosopher-king. But in actual, the appearance of chis ideal ruler is impossible. Therefore he finds the second best state in . Then does Plato gives up his dream of the ideal state or approaches to that closely? And ruler stands against laws or relates with partnership? This article deals with these problems. As last, we will compare Plato's ideal state and philosopher-king to God's kingdom and Jesus in the Bible.

Plato's Laws, Bk. 10 is made up of cryptically concise expressions and complex arguments, so that it is not simple to understand it. In this essay I would like to make use of Stoic perspective as an interpretative instrument, which would enable me, I hope, to reconstruct the main arguments of the Laws, Bk. 10 into an intelligible form. Through this approach we would have an opportunity to meet with some important philosophical ideas of Plato which did not reveal themselves clearly in other, especially early and middle dialogues. These ideas comprise the inseparability of the soul from the body, the intellectualization of nature, the human being as a part of the cosmos and the extensional overlapping of the moral law and the natural law. And at the same time my study would result in making a suggestion for history of reception. That is, in this paper I will find some grounds in the tenth book of the Laws that would show how great the influence of Plato upon the Stoics was. For we have but little knowledge about the possibility of the power of Plato's influence upon the Stoics, even though the scholarship on the Stoics until now shed some light on the features and range of Aristotle's influence upon them.

플라톤의 책에 대한 관념은 책에 대한 최고의 부정이다. 책의 세계는 진리의 이름으로 산출된 거짓의 세계라는 것이다. 글쓰기란 진리의 외면이기 때문이다. 플라톤의 이상국가에서는 시인은 추방되고, 책은 불태워져야 한다. 책의 위기란 그렇듯 문자가 태어날 때부터 있었다. 그러나 그 부정속에 글쓰기에 대한 최고의 긍정이 있다.

Plato's ontology is closer to Holism, which is based on IDEA, than to Dualism, which regards the matter and soul as being independently from each other. According to his metaphysics, the sensory things are the copies of IDEA. and IDEA is the original of them. Hence human body and soul are not separate from each other, but are ontologically continuous and functionally complementary. The reason why Plato's view of education, which pursues the perfection of the soul, emphasizes the physical training and makes it the premise of study is this ontology. It seems that Park Eun-sik, an independent activist in the late period of Joseon Dynasty, has a view of education similar to Plato's. He emphasized the importance of education on martial art in order to restore the our people's inner quality, 'Mind(心)'. Both Plato and Park Eun-sik thoughts that the education of physical training and martial art was the premise of study to make the humanity they pursued. And they expected that the talented people raised through the curriculum proposed by them would lead the prosperity of the nation by fulfilling their respective roles in society. In conclusion, from the view of Plato and Park Eun-sik's thoughts, it can be said that, the education of physical training and martial art for students is the premise of the study for personal perfection of human beings, and essential curriculum for making the ideal state that they dreamed.

The aim of this paper is to expound upon the concept of mental health and disease in Plato. In ancient Greece, philosophy was to care for the health of the soul and to pursue the happiness of the life, while medicine was to care for the health of the body. It is the role of philosophy that defines what the mental disease is, rather than the realm of medicine, and the practical function of philosophy is the life of caring for our souls. In order to take care of the soul, it is important to diagnose what the mental disease is and where it comes from. In ancient Greek, medicine disease was initially regarded as a divine punishment and healing as, quite literally, a gift from the gods. Plato, however, insists that mental illness is not just brain problem but a human whole problem, (2) it is caused by imbalance and discord, and (3) ignorance is also a mental disease, (4) and furthermore, injustice and vice are mental diseases as well. Therefore Plato argues that the aim of philosophy is to practice a virtue as the mental health and further to achieve political justice to maintain the health of the soul.

Following $G\ddot{o}del's$ own arguments, this paper explores his views on mathematics, its object, and mathematical intuition. The major claim is that we simply cannot classify the $G\ddot{o}del's$ view as robust Platonism or realism, since it is conceivable that both Platonistic ontology and intuitionistic epistemology occupy a central place in his philosophy and mathematics.
