These philosophers were all atheists, for they did not believe in the existence of God. Atheists may be very expert in mental speculation and may be so-called great philosophers, but they can be defeated by a Vaiṣṇava firmly situated in his conviction and God consciousness. Following in the footsteps of Śrī Caitanya Mahāprabhu, all the preachers engaged in the service of ISKCON should be very expert in putting forward strong arguments and defeating all types of atheists.
