verificationism
Verificationism is the doctrine of dragging every grand claim to the interrogation chamber of observable evidence. It banishes metaphysics from the elegant stage of theory, smashing it under the harsh fluorescent lights of the laboratory. It substitutes the spell of words with cold instruments, freezing heated debates into statistical frost. By plucking away the feathers of imagination and declaring only the visible to be truth, it becomes a tyrant that crushes the tender sprouts of wisdom.
