We wish to know what are the occurrences that make the word "or" useful. These occurrences are not to be sought in the facts that verify or falsify beliefs, which have no disjunctive quality, but are what they are. The only occurrences that demand the word "or" are subjective, and are in fact hesitations. In order to express a hesitation in words, we need "or" or some equivalent word.... … "[N]ot" must derive its meaning from experiences of rejection, and "or" from experiences of hesitation. Thus no essential word in our vocabulary can have a meaning independent of experience.

DEFINE: Defines the origins of logical connectives ('or', 'not') by grounding them in felt experiences of hesitation and rejection rather than external facts.
