Abstract

EVENTS CONSIST IN THE INSTANTIATION OF PROPERTIES IN SUBSTANCES. TWO WORDS WHICH RIGIDLY DESIGNATE PROPERTIES, PICK OUT THE SAME PROPERTIES, NOT JUST BECAUSE THE TWO PROPERTIES HAVE THE SAME CAUSES OR EFFECTS, BUT IF AND ONLY IF THE WORDS MEAN THE SAME. IT FOLLOWS THAT HAVING A RED AFTER IMAGE AND HAVING C-FIBRES FIRE ARE DIFFERENT PROPERTIES. ALTHOUGH THE INSTANTIATION OF TWO DIFFERENT PROPERTIES IN A SUBSTANCE MAY CONSTITUTE THE SAME EVENT, THAT WILL BE SO ONLY IF (IN GOLDMAN’S TERMINOLOGY) THE INSTANTIATION OF THE ONE LEVEL-GENERATES THE INSTANTIATION OF THE OTHER. THIS DOES NOT HOLD IN THE CASE OF MENTAL AND BRAIN EVENTS
