QUOTE : HUMAN BEINGS TEND to regard the conventions of their own societies as natural, often as sacred. One of the great steps forward in history was learning to regard those who spoke odd-sounding languages and had different smells and habits as fully human, as similar to oneself. The next step from this realization, the step which we have still not fully made, is the willingness to question and purposefully alter one’s own conditions and habits, to learn by observing others. If a particular arrangement is not necessary, it might be possible to choose to change it.
