According to Osho, the Charvakas’ contribution was to ignite a materialist, pleasure-affirming dissent in India, but they lacked rigorous argument and any great exemplar. Their debate remained low-level, never truly metaphysical or persuasive; without an Epicurus or a Hume, their stance failed to mature, endure, or significantly reshape India’s overwhelmingly belief-driven tradition.
They spoke up for enjoying life and denying the beyond, but without strong reasons or a great leader, so their ideas didn’t stick.
