Science can measure how much dopamine your brain releases when you eat chocolate. It can’t tell you whether you should eat the chocolate.
This distinction matters more than most people realize.
We live in a world that treats scientific knowledge as the highest form of truth. And for describing what exists, science is unmatched. It maps reality with stunning precision.
But “what is” isn’t the same as “what matters.”
Science tells us that humans and ants are both carbon-based life forms following evolutionary imperatives. It doesn’t tell us whether human suffering matters more than ant suffering. That’s a value judgment, not a factual claim.
The confusion happens because facts feel objective and values feel subjective. So we assume facts are more reliable guides for living.
But this misses something crucial: you can’t get an “ought” from an “is.” Knowing that sugar triggers pleasure responses doesn’t tell you whether pleasure is good. Knowing that cooperation increases survival doesn’t tell you whether survival is worth pursuing.
Even choosing to live by scientific principles is itself a value choice. You’re deciding that evidence and rationality matter. Science can’t prove they should.
I’m not dismissing science. I think it’s our best tool for understanding reality. But understanding reality isn’t the same as knowing how to live in it.
The map is not the territory. And the territory isn’t a moral guide.
