Sir Charles Eliot (1921) describes on about 400 pages the History and Influence of Buddhism in Asia and the Western World. This book includes a detailed biography of the author and an introduction by way of a literary critique. "The spread of Hindu and Buddhist thought was an intellectual conquest, not an exchange of ideas. On the north-western frontier there was some reciprocity, but otherwise the part played by India was consistently active and not receptive. The Far East counted for nothing in her internal history, doubtless because China was too distant and the other countries had no special culture of their own. Still it is remarkable that whereas many Hindu missionaries preached Buddhism in China, the idea of making Confucianism known in India seems never to have entered the head of any Chinese. "It is correct to say that the sphere of India's intellectual conquests was the East and North, not the West, but still Buddhism spread considerably to the west of its original home and entered Persia. But in Persia and its border lands there were powerful state religions, first Zoroastrianism and then Islam, which disliked and hindered the importation of foreign creeds and though we may see some resemblance between Sufis and Vedantists, it does not appear that the Moslim civilization of Iran owed much to Hinduism. "But in all Asia north and east of India, excluding most of Siberia but including the Malay Archipelago, Indian influence is obvious. Though primarily connected with religion it includes much more, such as architecture, painting and other arts, an Indian alphabet, a vocabulary of Indian words borrowed or translated, legends and customs. The whole life of such diverse countries as Tibet, Burma, and Java would have been different had they had no connection with India. "The influence of Indian religion on Christianity is part of the wider question of its influence on the west generally. It is clear that from 200 B.C. until 300 A.D. oriental religion played a considerable part in the countries round the Mediterranean. Charles Eliot expresses the view that: 'When all allowance is made for similar causes and coincidences, it is hard to believe that a collection of such practices as clerical celibacy, confession, the veneration of relics, the use of the rosary and bells can have originated independently in both religions'."
