If [the student “rebels”] “seem unable to formulate or sustain a systematized
political theory of society,” yet shriek with moral righteousness that they
propose to achieve their social goals by physical force—hasn’t Logical
Positivism taught them that ethical propositions have no cognitive meaning and
are merely a report on one’s feelings or the equivalent of emotional
ejaculations? If they are savagely blind to everything but the immediate
moment—hasn’t Logical Positivism taught them that nothing else can be claimed
with certainty to exist?
