The concept of dialectic in Plato's philosophy مقالة

ملخص الجهاز:

According to Plato, in the stage of dianoia (rational reasoning), the soul in research and investigation is forced to start from a hypothesis with the help of imitating images and move towards the result and not towards a first principle; for example, in geometry, the mind moves towards the result from hypotheses, using a trained shape. 4- The fourth meaning of dialectic is stated in the Republic dialogue, and it is the education and training of philosopher rulers or wise rulers, which ultimately leads to the "highest form," which is the idea of the Good. In the Republic dialogue (sections 504 and 505), Plato says: "Dialectic is the highest of knowledge and its subject is the idea of 'Good,' and justice and other human capabilities are good and beneficial only because of benefiting from it. In section 532 of the Republic dialogue, Plato states: Whoever walks on the path of dialectic does not seek help from the senses but only with the power of reason and by seeking help from abstract concepts reaches the true being of each thing. In the Republic dialogue, section 510, Plato says that those who work with geometry and mathematics whenever they want to examine something, place assumptions such as the concepts of odd and even, geometric shapes, and three types of angles as the basis of their work. Plato's dialectic, in its final stage, is negative and destructive, because its goal is to destroy assumptions and reach a first principle without assumptions, which is the idea.
