This essay defends rationality against modern fundamentalism and postmodern critiques, drawing parallels between classical Greek drama and Indian philosophy. Highlighting quotes from Sophocles, Euripides, and the Yogavāsiṣṭha, it underscores that reason must be continuously cultivated. In ancient India, the heterodox Cārvāka materialists stood out as uncompromising rationalists who rejected uncritical scriptural authority.
