Anthropic principle Quote by Carl Sagan
““There is something stunningly narrow about how the Anthropic Principle is phrased. Yes, only certain laws and constants of nature are consistent with our kind of life. But essentially the same laws and constants are required to make a rock. So why not talk about a Universe designed so rocks could one day come to be, and strong and weak Lithic Principles? If stones could philosophize, I imagine Lithic Principles would be at the intellectual frontiers.””

Source Speech: Interview on cosmology, 1990s
The Anthropic Principle focuses on conditions for life, but similar conditions also allow non‑living structures like rocks, suggesting a broader “Lithic Principle” for matter.
In simple terms: Life‑friendly laws also make rocks; consider a rock‑centric view of the universe.
