There are four experiences that lead us to talk of 'some' things [Russell]
     Full Idea: Propositions about 'some' arise, in practice, in four ways: as generalisations of disjunctions; when an instance suggests compatibility of terms we thought incompatible; as steps to a generalisation; and in cases of imperfect memory.
     From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5)
     A reaction: Modern logicians seem to have no interest in the question Russell is investigating here, but I love his attempt, however vague the result, to connect logic to real experience and thought.
