Living life without faith in God’s heaven or society’s Utopia requires using your mind.

“As products of the split between man’s soul and body, there are two kinds of teachers of the Morality of Death: the mystics of spirit and the mystics of muscle, whom you call the spiritualists and the materialists, those who believe in consciousness without existence and those who believe in existence without consciousness. Both demand the surrender of your mind, one to their revelations, the other to their reflexes. No matter how loudly they posture in the roles of irreconcilable antagonists, their moral codes are alike, and so are their aims: in matter—the enslavement of man’s body, in spirit—the destruction of his mind.

The good, say the mystics of spirit, is God, a being whose only definition is that he is beyond man’s power to conceive—a definition that invalidates man’s consciousness and nullifies his concepts of existence. The good, say the mystics of muscle, is Society—a thing which they define as an organism that possesses no physical form, a super-being embodied in no one in particular and everyone in general except yourself. Man’s mind, say the mystics of spirit, must be subordinated to the will of God. Man’s mind, say the mystics of muscle, must be subordinated to the will of Society. Man’s standard of value, say the mystics of spirit, is the pleasure of God, whose standards are beyond man’s power of comprehension and must be accepted on faith. Man’s standard of value, say the mystics of muscle, is the pleasure of Society, whose standards are beyond man’s right of judgment and must be obeyed as a primary absolute. The purpose of man’s life, say both, is to become an abject zombie who serves a purpose he does not know, for reasons he is not to question. His reward, say the mystics of spirit, will be given to him beyond the grave. His reward, say the mystics of muscle, will be given on earth—to his great-grandchildren.

Selfishness—say both—is man’s evil. Man’s good—say both—is to give up his personal desires, to deny himself, renounce himself, surrender; man’s good is to negate the life he lives. Sacrifice—cry both—is the essence of morality, the highest virtue within man’s reach.”
- From Galt’s speech

Who would want to? How do you know the Deity is imaginary? Do you know the description of life? I do! I learned it in high school.

I am constantly amazed at people who fear God and try to force their ideas on others. You must admit the Ten Commandments are truly great. And religion brings comfort to so many people. I find no fault in that!
