Yet at the same time, Mahalanobis was also representative of a specifically Indian rationalist tradition. Sankhya meant not only ‘number’ but something like a rational understanding of the universe. Mahalanobis’s family, from the famous small Brahmin gentry of Bikrampur in East Bengal, had converted to the rationalistic strain of the reforming Brahmo Samaj. His father was an activist in the widow re-marriage campaigns of the mid-nineteenth century. Mahalanobis himself was connected with the Samaj throughout his life, opposing the reintroduction of rituals and paying homage to the memory of the founder of the Samaj, Rammohan Roy. In fact it is striking how many of the Bengali intellectuals of the Independence generation, including Satyajit Ray, the film-maker and Nirad Chaudhuri, the self-declared ‘Unknown Indian’, were Brahmos or were influenced by the Samaj. For his part Mahalanobis declared that he was not a Hindu, but added paradoxically, a ‘Brahmo by religion.’ He also revered the great Bengali sage, Rabindranath Tagore, himself a covert Brahmo. So Mahalanobis’s cultural and religious stance stood on that intriguing Indian cusp between pantheism and what might be called ‘pan-atheism.’ As he once said, the human race would be improved by ‘thinking about him who cannot be known, by trying to know.’
