Decisive Criticism

A decisive criticism contradicts the idea it targets: if you accept the criticism, you cannot rationally also accept the idea, because both cannot be true. It says an idea is an error that will cause failure at a specific purpose, in a context. This is the central commitment of Yes or No Philosophy: every criticism is either decisive (it refutes the idea) or it does nothing at all. An idea cannot partially survive a criticism.

This is where CF goes beyond Critical Rationalism. Popper rejected positive arguments and induction, but still let us form a critical preference for whichever surviving idea seems best given the weight of the arguments. CF rejects that residue. It denies argument strength entirely: there are no strong or weak arguments, no gradations of certainty, no weighing. An “argument” that only nudges your estimate is indecisive, and an indecisive argument has no logical connection to its conclusion — you can accept it and still deny the conclusion without contradiction.

Why insist on this? Errors have logical priority over merits: one fault can sink an idea no matter how many good traits it has, so no pile of positives ever proves success. Criticism is also asymmetrically cheap — one counter-example refutes “all ravens are black,” while a million black ravens prove nothing.

CF holds that many positive and degree arguments are convertible to decisive negative form (criticize the alternatives, or specify a good-enough breakpoint that turns a flaw into failure). Arguments that resist conversion are, CF conjectures, simply mistaken. The conclusion you reach is the non-refuted idea you tried and failed to refute.
