‘India In The Eyes Of Europeans’ by Martin Farek, one of the scholars of the Comparative School of Cultures in the Czech Republic; is a book that analyses the biases of the Christian European scholarship in interpreting all that is foreign to it; especially the way that scholars influenced by Christian theology, Western and Indian alike, view Indian and more specifically Hindu history.
Two decades after initially releasing his book, the author still holds the same biases regarding AIT without having come to terms with recent developments.
