The correct answer is: A. Plato.
Plato was a Greek philosopher who lived in the 5th and 4th centuries BC. He is considered one of the founders of Western philosophy, and his work has had a profound influence on subsequent philosophers, including Aristotle, Thomas Aquinas, and René Descartes.
Plato’s most famous work is the Republic, in which he discusses the nature of justice and the ideal state. In the Republic, Plato argues that man is a social animal and that he cannot live without society. He says that “man without society is either a beast or a God.”
Plato’s view of man as a social animal is based on his belief that man is naturally inclined to live in a community with others. He argues that man is a rational animal, and that reason is the highest part of the soul. Reason, he says, is the faculty that enables us to understand the world around us and to make decisions about how to live our lives.
Plato also believes that man is a political animal. He argues that man is naturally inclined to participate in government and to make decisions about how to run the community. He says that man is a social animal because he needs others to help him fulfill his potential.
Plato’s view of man as a social animal has been influential in Western thought. It has been used to justify a variety of political systems, including democracy, socialism, and communism. It has also been used to justify a variety of social programs, such as welfare, education, and healthcare.
Plato’s view of man as a social animal is not without its critics. Some critics argue that man is not naturally inclined to live in a community with others. They argue that man is naturally inclined to be selfish and to look out for his own interests. They also argue that man is not naturally inclined to participate in government or to make decisions about how to run the community.
Despite these criticisms, Plato’s view of man as a social animal remains influential in Western thought. It is a view that has been used to justify a variety of political systems and social programs. It is also a view that has been used to explain the nature of man and his place in the world.
