Think always in the spirit of "we"; this is universal thinking and breeds tolerance and understanding. Remember, what makes you happy will also make others happy. So, learn to share in your thinking and actions. We are all our brother's keeper, and evolve only as a family. –Alfred J. Parker

Love without possession is the great secret of a happy life. –Alfred J. Parker

No human investigation can be called real science if it cannot be demonstrated mathematically. –Leonardo da Vinci

Know that a wise man changes his mind; but a fool never. Be humble, and thus keep the door to wisdom always open. Ego is the greatest destroyer of potential thinkers. Be principled, just, and honest at all times; and peace, health, and success will follow you all the days of your life. –Alfred J. Parker
