“… Learn the morality implied in the Declaration of Independence, a document that today isn’t quoted enough nor sufficiently understood. The Objectivist ethics is merely the philosophically-worked-out proof of what the Founding Fathers implied in the Declaration. …” -- Ayn Rand Answers pg. 47: "What political steps should be taken to achieve your goals?"
This group states, “Objectivism stands opposed to religious ethics…”
The ethics of an INDIVIDUALIST, a moral descendant of the Founders, is self-interest. One need not be an atheist to be an individualist, to achieve glorious feats:
"The concept of individual rights is so prodigious a feat of political thinking that few men grasp it fully—and two hundred years have not been enough for other countries to understand it. But this is the concept to which we owe our lives—the concept which made it possible for us to bring into reality everything of value that any of us did or will achieve or experience." -- Ayn Rand
A proper philosophy is integrated. An honest man does not drop context. Yet, this group does not mention the ultimate goal of Objectivism: capitalism, the only social system concordant with individual rights.
One need not be an atheist to fight for rights and capitalism.
As to private faith:
“The only good which men can do to one another and the only statement of their proper relationship is — Hands off!” -- Howard Roark, The Fountainhead by Ayn Rand
