“ There was a time when all Indo-Europeans made up one people and spoke one common language, as has now been established by linguists through a comparison of the old and new Indo-European languages. But the old situation, in which all Indo-Europeans understood one another, gradually broke down and disappeared and a new set of circumstances arose in which there came about a splitting of the language, of the common national awareness, the common language, into various languages, beliefs, attitudes, traditions, etc. ”
