Extracted from S. K. Belvalkar and R. D. Ranade’s History of Indian Philosophy (1927), this study examines the radical radicalism of Ajita Keśakambalin. Drawing from the Sāmaññaphala Sutta, the authors explore his rejection of ritualism, his four-element physicalism, and his place as an early precursor to full-fledged Cārvāka thought.
