logical positivism
Logical positivism is the playground of philosophers lazy enough to declare non-existent entities non-existent. It confines all meaning to what can be observed and verified, dismissing abstract questions more thoroughly than ever. Metaphysical anguish is thrown away as "meaningless verbiage," and reason is caged under the name of measurability. Theories become both lab rats and poison testers, forced to survive inside the cage or quietly vanish without troubling the authorities. In the end, it proclaims "Only what we can experience for certain is real," and that echo resounds alone.
