Neil deGrasse Tyson: Why astrology unravels civilization

Tyson notes that roughly 80% of Gen Z believe in astrology and many use it to guide major life decisions. He argues this is tolerable only while it’s not universal; if belief in horoscopes approached 100%, society would regress to a ‘cave’ mindset where unexplained phenomena are attributed to mysterious forces instead of investigated. He stresses that when people value what they *think* is true over what *is* true, it becomes ‘a recipe for the unraveling of civilization,’ especially once such thinking influences laws and policy.

By matching the elemental makeup of our bodies (hydrogen, oxygen, carbon, nitrogen) to that of the universe, Tyson shows we are literally made of stardust. He argues we’re not just alive *in* the universe; ‘the universe is alive within us.’ This perspective, he says, ‘borders on the spiritual’ yet is a scientific result, dissolving superficial differences (race, tribe, nationality) and highlighting our deep kinship with all life—including sharing DNA with bananas and fungi.

Tyson rejects the idea that meaning is an external treasure to be discovered ‘under a rock’ or handed down. He insists that we each have the power—and responsibility—to *make* meaning by learning daily, reducing others’ suffering, and turning information into wisdom. For him, mortality is essential to focus and purpose: if we lived forever, we’d have no urgency and ‘mathematically… a life of no meaning at all.’ His guiding maxim: ‘Be ashamed to die until you have won some victory for humanity.’

After initially giving blunt, dismissive answers about God, Tyson deliberately read widely across religious texts (Torah, Qur’an, Mormon writings, Jehovah’s Witness literature, etc.) to converse more respectfully and knowledgeably with believers. He argues religion has been one of the greatest forces shaping civilization, but also a major source of tribal division and war. He suspects that church’s greatest social value may be in the *ritual community* it creates—regularly bringing people together in a way that modern, atomized life increasingly does not.

Tyson emphasizes that being scientifically literate means caring about what *is* true, not what we wish to be true. He encourages questioning instead of outright accepting or rejecting claims (about crystals, Mercury retrograde, conspiracies, etc.), warning that confidently held ignorance makes education much harder. His advice: never overvalue your own thoughts; instead, aim to be ‘humbled daily with new ideas that challenge’ what you currently think. This stance, he argues, is the antidote to dogmatism and polarization.
