Legality/Identification/Identifiability/Individuation/Law/legal/Millikan: Properties are identifiable only because they are involved in legal procedures.
Substances: are only identifiable because they have properties.
Concept/Test/Millikan: is it necessary to make inferences of sentences in which tokens of concepts occur, in order to test the theory?
Knowledge: we need knowledge about the use of concepts in actions, not in conclusions. And that would be impossible if the facts did not occur in laws.
N.B.: But it does not follow that we need to know these laws at all. For example, to distinguish between red and green, we need to know no law of optics. I could do it anyway before I learned any law.
Conviction/belief/Millikan: I can also develop beliefs about objects without having developed any theories about the entities of which the concepts are about in my beliefs._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
