Understanding this quote
What it means
True novelty means something genuinely unprecedented, not just a new arrangement of existing elements. Crick argues that deterministic processes can only produce outcomes predictable from prior states—elaborate, but not truly new. Only chance—random mutation, random quantum events, unpredictable accidents—introduces something the universe hasn't seen before. Without randomness, reality would just replay itself indefinitely. Chance is the wild card that breaks causal chains and makes genuine innovation possible.
Relevance to Francis Crick
Crick co-discovered DNA's double helix—the molecule encoding life's instructions. His work showed random mutations in DNA sequence, not design, drive evolution's creative power. He arrived at biology by chance himself: WWII destroyed his physics research, redirecting his career. A committed atheist and materialist, Crick believed life and consciousness emerge from chemistry alone, with no guiding hand—making chance the only available architect of genuine novelty.
The era
Crick worked amid two revolutions: quantum mechanics had proven subatomic events are irreducibly random, and molecular biology was rewriting life as chemistry. Jacques Monod's 1970 book Chance and Necessity echoed this view—life arose from random mutation, not cosmic purpose. The Cold War era's secular scientism pushed back against religious determinism. DNA's discovery made the mechanism of random mutation concrete and measurable, grounding philosophical claims about chance in hard molecular evidence.
