The East has been upsetting and sometimes even revolutionizing Europeans’ modes of thought, feeling and enjoyment since the most ancient times, well before Marco Polo, when it transmitted its techniques and arts (printing, paper money, the compass, porcelain, etc.). From the 18th century Europe has played a similar role in the technological and even the philosophical field, with regard to India, China and Japan. Apart from the infrequent exchanges between West and East, the transmission of knowledge was carried out through ‘buffer civilizations’ - Persians, Sassanids, the Turkic-Iranian Muslim world - whose languages were Indo-European or whose religion was Abrahamic, and so culturally linked to the West. Thus it was to the east of them that the great frontier between civilizations was situated, in a region that, since around the seventh century, has been dedicated to Islam. The huge Euro-Asian bloc was the arena for several encounters, or clashes, between civilizations which considerably enriched the technical skills, culture and taste of Europeans; the transmission of Greco-Arab knowledge in the 12th century, the contribution of Chinese techniques thanks to the great Asian land routes (christened the Silk Road in the 19th century), the importation of Indian techniques over the sea routes. These encounters were also the occasion for two-way trade that gave a new face to countries like India or Japan; the latter, for instance, opened up not only to western technologies in the Meiji period, but also to the philosophies of Husserl and Heidegger in the early 20th century (the case of the Kyôto School of philosophy should be mentioned). The last of the great encounters date from the late 19th and the 20th centuries at the very moment when Europe and the American world were claiming to be the only ‘civilization’ worthy of the name, and considered they had nothing to learn from others, but, on the contrary, could teach them everything. However, this was also the time when a deepening knowledge of India, China, Korea, Japan led to a ‘rediscovery’ of Asia as a continent of great and rich civilizations whose philosophies, arts and many other disciplines were a match for their European counterparts; the French writer Henri Michaux described himself as a ‘barbarian’ when he visited that part of the world at the beginning of the 20th century.
