Conjecture and Refutation
Popper's account of how knowledge actually grows — not by gradual accumulation of confirmed facts but by the rhythm of bold hypothesis and severe test, in which neither half works without the other.
Conjecture and refutation is the operational method of critical rationalism. Knowledge advances when a bold conjecture is subjected to the most severe test its proposer can devise. If the conjecture survives, it earns provisional standing — not truth, but the specific trust of the tested. If it fails, the failure is information: it tells us something true about the world by revealing what the world is not. Popper insisted that both halves are essential. Conjecture without refutation is speculation, however brilliant. Refutation without conjecture is sterile criticism, capable of destroying but not of building. The growth of knowledge requires the alternation: creative leap, critical landing, revised leap, more severe landing. The AI moment has disrupted this rhythm by supercharging one half and leaving the other exactly where it was.
