I would say that introverts make some of the best international philosophers. The less common attribute of the introverted lifestyle - a close societal connection, as such a connection disappears or changes in relevance as the currents of the winds change - leaves too much room for one's own cultural bias. Instead, introverts tend to turn inward, the laboratory of being and all its forms. This is the most accurate study of the individual human being, which is in turn, rather than those affected by cultural limitations, the most universal reflection of human understanding and human behavior.
