Open a book and turn a page. Let your mind wander through another persons thoughts. See what is before you and understand a new thing. Change the direction of your life. Know that you will not agree with everyone, but be open to see from their perspective. Decide for yourself if what you have read suits you. Then respond if you feel the need to make a different argument. Ideas must flow and be exchanged in order for understanding to take root. Oppression and suppression of new thoughts is not an option that a free person can abide, so the exchange of ideas must go on.
