Much has been made of Kant's Scottish ancestry but his debt to Kerala has scarcely been acknowledged. Recently, Shashi Tharoor's daring 'de-Kanting' (as Prof. Binmore puts it) and re-formulation of Ethics has re-opened the whole question of Malyalee- in particular Shree P. Menon's- influence on Kant.
Menon Sahib, whom Kant addressed as Prolego (Prahalad? Palghat?), had a great influence on Kant' views though, with typical European condescension the sage of Konisberg wrote a letter of introduction for Prolego Menon to all future Metaphysics. This gives us the clue that Shri P. Menon may have been a student or, more likely, a waiter at a South Indian Restaurant and had requested this favor from the German philosopher.
