Quote from ‘Second Talk to the Phil. Club [and] Second Talk. On Deduction’
Several years reconsideration leads to this new definition. Not necessary but compulsive reasoning. [—] Deduction points to the premisses & to their relation & then shakes its fist in your face and tells you “By the eternal powers, you have got to admit the conclusion.[“] [—] Compulsive means that you are logically forced to admit the conclusion.
MS [R] 754
