In other words, I claim, if we really want to improve our judgment as individuals and as societies, what we need most is not more instruction in logic or rhetoric or probability or economics, even though those things are quite valuable.
En altres paraules, us dic que si volem millorar  el nostre criteri com a persones i com a societats, no necessitem més educació en lògica, ni en retòrica, probabilitat o economia, malgrat que aquestes tinguin molt valor.
