Hostility which goes along with solidarity and understanding in objective matters is indeed, so to speak, clean and certain in its justification. The consciousness of such a differentiation assures us that we do not harbor personal antipathy where it does not belong. But the good conscience bought with this discrimination may under certain circumstances lead to the very intensification of hostility. For where hostility is thus restricted to its real center, which at the same time is the most subjective layer of personality, we sometimes abandon ourselves to it more extensively, passionately, and with more concentration than when the hostile impulse carries with it a ballast of secondary animosities in areas which actually are merely infected by that center.
