Defining Ancient Greek Skepticism
Ancient Greek skepticism, rooted in the term "skepsis," challenges you to investigate knowledge rather than accept beliefs at face value. It emphasizes the suspension of judgment, or epoch, especially when faced with conflicting evidence. This approach encourages you to rethink what you know and to adopt a critical attitude toward knowledge claims.
In a similar vein, ethical considerations in educational data mining emphasize the importance of questioning the reliability and implications of data used in education.
Within ancient skepticism, two main forms emerged: Academic skepticism, which questions the possibility of certain knowledge, and Pyrrhonian skepticism, which advocates for a life free from belief and assertion. Figures like Pyrrho, founder of Pyrrhonism, and Arcesilaus, who led the Academy towards skepticism, highlighted the limitations of human knowledge. They argued that certainty is often unattainable.
Carneades, a key figure after Arcesilaus, introduced a practical criterion called "to pithanon," guiding you to rely on convincing impressions in your actions despite the uncertainty inherent in knowledge.
