  With regard to Islam, it should first of all be pointed out that classic Islamic philosophy, with its roots in classical Greek philosophy, is not Eastern in the same sense as Buddhist, Vedantic, Chinese, and Japanese thought. It shares roots with Augustinianism and Thomism, and thus with some of the traditions that have been central to the development of personalism in the West. On the other hand, it has been observed that there is no conceptual equivalent of the Western philosophical concept of “person” in Arabic and in classic Islamic philosophy, something which would seem to confirm the importance of the specifically Christian, to a considerable extent Trinitological, terminological and conceptual origins of the term. But as there are other sources of personalism than the Trinitological thought that was decisive for the early formation of the concept (when, it should also be remembered, it was not yet fully personalistic in the modern sense), and as these sources have also produced Jewish versions of personalism, the historical absence of a conceptual equivalent in Arabic has not precluded the development of Islamic personalism. Themes with regard to the self and the nature of God which are very similar to those of Western personalists are found in a modern Muslim thinker like Muhammad Iqbal (1877–1938). Mohammed Aziz Lahbabi (1922–1993) explicitly sought to develop a Muslim version of personalism, and was influenced not least by Mounier.
