Individualism and the Western Liberal Tradition argues that ethnic influences are important for understanding the West. The prehistoric invasion of the Indo-Europeans had a transformative influence on Western Europe, inaugurating a prolonged period of what is labeled "aristocratic individualism" resulting form variants of Indo-European genetic and cultural influence. However, beginning in the seventeenth century and gradually becoming dominant was a new culture labeled "egalitarian individualism" which was influenced by preexisting egalitarian tendencies of northwest Europeans. Egalitarian individualism ushered in the modern world but may well carry the seeds of its own destruction.
