"Rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law' because law is often but the tyrant's will, and always so when it violates the rights of the individual." - Thomas Jefferson.
"The major difference between a thing that might go wrong, and a thing that cannot possibly go wrong, is that when a thing that cannot possibly go wrong, goes wrong, it usually turns out to be impossible to get at or repair." - Douglas Adams.
"Optimist: The glass is half full. Pessimist: The glass is half empty. Scientist: Look, the glass is half full of water and half full of air, so it's completely full. What is the world coming to?" -Crucial Mistake's sig (maybe former sig)
"Pessimism is, in brief, playing the sure game. You cannot lose at it; you may gain. It is the only view of life in which you can never be disappointed. Having reckoned what to do in the worst possible circumstances, when better arise, as they may, life becomes child's play." - Thomas Hardy.
