I am re-posting this only because I think that everyone, regardless their beliefs or lack of them, should live by these rules.
TEN COMMANDMENTS FOR A GLOBAL HUMANISM
1- Proclaim the natural dignity and inherent worth of all human beings, in all places and in all circumstances.
2- Respect the life and property of others at all times.
3- Practice tolerance and open-mindedness towards the choices and life styles of others.
4- Share with those who are less fortunate and mutually assist those who are in need of help.
5- Use neither lies, nor spiritual doctrine, nor temporal power to dominate and exploit others.
6- Rely on reason, logic and science to understand the Universe and to solve life’s problems, avoiding superstitions, which numb the mind and are an obstacle to thinking for oneself.
7- Conserve and improve the Earth’s natural environment – land, soil, water, air and space – as humankind’s common heritage.
8- Resolve differences and conflicts cooperatively without resorting to violence or to wars.
9- Organize public affairs according to individual freedom and responsibility, through political and economic democracy.
10- Develop one’s intelligence and talents through education and effort, in order to reach fulfillment and happiness, for the betterment of humanity and of future generations.
