The problem I wish to consider is: What do we know in these cases, where the subject is merely described ? I have considered this problem elsewhere1 from a purely logical point of view; but in what follows I wish to consider the question in relation to theory of knowledge as well as in relation to logic, and in view of the above-mentioned logical discussions, I shall in this paper make the logical portion as brief as possible. In order to make clear the antithesis between 'acquaintance' and
