Carneades
Carneades was a Greek philosopher who served as the head of Plato's Academy from approximately 165 to 137 BCE. He is best known for his development of Academic skepticism, which he refined into a more systematic school of thought, often referred to as the New Academy. He argued against the Stoic criterion of truth, holding that no certain knowledge is possible, and that we should rely on probable impressions to guide action. He is famous for his arguments against the existence of gods and for his defense of the idea that justice is based on utility. His teachings, preserved through his students, including Clitomachus, had a profound influence on the history of skepticism.
Who was Carneades and what is he known for?
Carneades was a Greek philosopher who became the head of Plato's Academy in the 2nd century BCE. He is known for his development of Academic skepticism, which he refined into a more systematic school of thought, often called the New Academy. He argued against the Stoic criterion of truth, holding that no certain knowledge is possible. He proposed that we rely on probable impressions to guide action. His teachings, preserved by his student Clitomachus, have had a lasting influence on the history of philosophy, particularly on skepticism and epistemology.
What is Carneades's view on the criterion of truth?
Carneades rejected the Stoic claim that there is a clear and distinct impression that serves as a criterion of truth. He argued that no impression is so clear or self-evident that it cannot be mistaken or doubted. Instead, he proposed that we should rely on probable impressions, which are those that appear to be true and are consistent with other perceptions. He developed a sophisticated classification of probabilities to guide action without claiming certainty. This view challenged the dogmatic epistemologies of his time and became a hallmark of Academic skepticism.
What is the difference between Carneades and Arcesilaus?
Carneades and Arcesilaus are both associated with the skeptical turn in the Academy, but there are differences in their approaches. Arcesilaus, who initiated the Middle Academy, argued for the suspension of judgment on all matters, following a more radical skepticism. Carneades, who led the New Academy, modified this position, arguing that while certain knowledge is impossible, we can still adopt probable judgments as a guide to action. Carneades's skepticism was more practical and less radical, allowing for a degree of probability in decision-making while still rejecting certainty.
What is the significance of Carneades's arguments against the gods?
Carneades is famous for his arguments against the existence of gods, which he presented as part of his skeptical method. He used the example of a man who navigates a storm by a rope to argue that the gods do not intervene in human affairs. He also argued that the existence of evil is incompatible with the idea of a benevolent deity. These arguments were not intended to promote atheism but to show that dogmatic beliefs about the gods are unfounded and that we should suspend judgment on such matters. His arguments have been influential in the history of religious skepticism and philosophy of religion.
What is Carneades's view on justice?
Carneades argued that justice is not a natural virtue but is based on utility and social convention. He famously presented two speeches on justice in Rome, one arguing that justice is a necessary virtue for social order, and another arguing that justice is merely a product of human agreement and has no foundation in nature. This exercise in arguing both sides of a question demonstrated his skeptical method of showing that every claim can be met with an equally plausible counterargument. His views on justice have influenced later thinkers, including the development of social contract theory.
What is Carneades's legacy in philosophy?
Carneades's legacy is significant. He is remembered as one of the most important figures in the history of philosophical skepticism. His development of Academic skepticism, particularly his concept of the probable as a guide to action, influenced later thinkers, including Sextus Empiricus, who preserved his ideas. His arguments against dogmatic certainty and his method of arguing both sides of a question have been influential in the development of critical thinking and dialectic. He is also remembered as a key figure in the history of the Platonic Academy, marking a period of its most vigorous engagement with skepticism.
What are Carneades's major contributions to philosophy?
Carneades's major contributions include his development of Academic skepticism into a more systematic and practical school. He introduced the concept of the probable as a guide to action, distinguishing between different degrees of probability. He also made significant contributions to the debate on the criterion of truth and to the philosophy of religion and justice. His method of arguing both sides of a question, known as the 'Carneadean method,' became a hallmark of his philosophical practice. His ideas have had a lasting impact on the history of epistemology and skepticism.
Who were Carneades's students?
Carneades had several prominent students, the most important of whom was Clitomachus, who succeeded him as the head of the Academy. Clitomachus was responsible for preserving and spreading his teacher's ideas, and he played a key role in the development of Academic skepticism. Other students included Charmadas and Metrodorus, who also contributed to the spread of Carneades's philosophy. Through his students, Carneades's influence extended well beyond his lifetime, shaping the course of skeptical thought in antiquity.
