We Are Made Of Starstuff.

Ask Courageous Questions. Do Not Be Satisfied With Superficial Answers. Be Open To Wonder And At The Same Time Subject All Claims To Knowledge, Without Exception, To Intense Skeptical Scrutiny. Be Aware Of Human Fallibility. Cherish Your Species And Your Planet.

Our Obligation To Survive And Flourish Is Owed Not Just To Ourselves But Also To That Cosmos, Ancient And Vast, From Which We Spring.
