What does Nietzsche conclude in Beyond Good and Evil?

Nietzsche asserts that the Indo-Germanic are the most advanced culture when it comes to developing philosophies for the modern age. The author disparages other cultures such as Muslims whose language is not as expressive or adequate enough to develop worthwhile hypotheses to examine man's will to truth.

Whether or not it was Nietzsche's intention, Beyond Good and Evil seems to suggest that if all cultures had the ability to interpret ancient and modern philosophies in the appropriate language and tempo, then the learned world would be of one mind.
