This article throws light upon the six major limitations of Plato’s theory. 1. Plato has classified the people into three classes according to innate abilities. That is contrary to human psychology. There are various classes of people because each individual differs from others. This is psychologically sound. 2. Society has been stratified into three rigid classes. It hampers social progress. From social point of view, this stratification is not tenable. 3. Education was meant for the upper and leisured class. He himself belonged to the upper strata. The common people and the manual labourers were deprived of education. This is undemocratic. Class consciousness was very dominant in those days. Plato was highly influenced by this class consciousness. 4. Education did not pay attention to vocation. Plato advocated education for culture. He developed a cultural and liberal scheme of education. ‘Liber means book. Hence liberal education means bookish education. Books were regarded as the highest product of human talent and experience. Agriculture and industry were completely neglected in Plato’s scheme of cultural education. 5. Every individual should serve the society according to his best abilities and capacities. But Plato did not show how an individual should apply his theoretical knowledge into practice. Though Plato himself was a great thinker and philosopher, he did not participate in the state or social activities of the day. He refused the governorship of Syracuse. He did not show how knowledge derived through dialectic method could be applied to practice. 6. Our mental life constitutes of three elements — emotional, intellectual and volitional. Plato only gave emphasis on the intellectual aspect of mind. Knowledge is unified, an organic whole. Connective or motive aspect is-very important in our behaviour. The source of action is within the individual. Plato has failed to realise the interrelation between volitional and intellectual aspects. In spite of these limitations in Plato’s scheme of education he is regarded as the greatest democratic educator of the world.
