subjective sphere of personality. In the interest of association, and of social coherence, each must know certain things with reference to the other; and this other has not the right to resist this knowledge from the moral standpoint, and to demand the discretion of the other; that is, the undisturbed possession of his being and consciousness, in cases in which discretion would prejudice social interests. The business man who enters into a contractual obligation with another, covering a long future; the master who engages a servant; and, on the other hand, this latter, before he agrees to the servile relationship; the superintendent who is responsible for the promotion of a subordinate; the head of a household who admits a new personality into her social circle—all these must have the right to trace out or to combine everything with reference to the past or the present of the other parties in question, with reference to their temperament, and their moral make-up, that would have any relation to the conclusion or the rejection of the proposed relationship. These are quite rough cases in which the beauty of discretion—that is, of refraining from knowledge of everything which the other party does not voluntarily reveal to us—must yield to the demands of practical necessity. But in finer and less simple form, in fragmentary passages of association and in unuttered revelations, all commerce of men with each other rests upon the condition that each knows something more of the other than the latter voluntarily reveals to him; and in many respects this is of a sort the knowledge of which, if possible, would have been prevented by the party so revealed. While this, judged as an individual affair, may count as indiscretion, although in the social sense it is necessary as a condition for the existing closeness and vitality of the interchange, yet the legal boundary of this invasion upon the spiritual private property of another is extremely difficult to draw. In general, men credit themselves with the right to know everything which, without application of external illegal means, through purely psychological observation and reflection, it is possible to ascertain. In point of fact, however, indiscretion exercised in this way may be quite as violent, and morally quite as unjustifiable, as listening at keyholes and prying into the letters of
