Thou shalt not believe in preposterous things, especially gods.
Thou shalt believe only in things that are founded on evidence and good reason.
Thou shalt not use faith as a basis for thy beliefs, for faith is anathema to reason.
Thou shalt shalt stop using the word "faith", for it is ambiguous and misleading.
Thou shalt accept with grace those things you once believed but later turned out to be wrong.
Thou shalt update thy beliefs with better data.
Thou shalt not pollute the earth.
Thou shalt not permit corporations to take over the world.
Thou shalt not have more than two or three children. Four or more offspring is vulgar. Five is right out.
If anyone among you claims to know what god wants, you shall take him or her unto a psychiatric hospital and commit him or her.
