Poets have frequently sought to arouse our pity, and it may be our fear as well, through the presentation of conflicts of this kind, following the rule of Aristotle, who lays it down that fear and compassion are objects of tragedy. Strictly speaking we experience neither fear nor reverence when confronted with rights which only exist among barbarians and are the misfortune of uncivilized times. Any compassion which such situations are likely to arouse is almost immediately converted into a spirit of indignant hostility. The only true artistic _dénouement_ of such a conflict is one where we find such illegitimate rights are not carried into execution, as, for example, neither Iphigenia nor Orestes are respectively sacrificed in Aulis and Tauris. (_γγ_) The _third_ and last class of that type of collision which is based on purely natural condition is that which is duetto personal passion caused by natural peculiarities of temperament and character. The jealousy of Othello is a supreme example of this. Ambition, avarice, nay, even love itself in certain aspects, will furnish other illustrations. Collision of this kind is only properly referred to such passions in so far as individuals, seized and dominated exclusively by the power of such emotions, are thereby forced into antagonism with the truly ethical constitution and inherently justifiable course of human existence, and consequently are plunged into a still more serious conflict. This carries our inquiry into the consideration of that third subdivision of our original classification of general types of collision, the type of which is based exclusively upon the conflict of spiritual forces, in so far as such opposition is the result of human activity. (_γ_) We have already observed when dealing with purely natural collisions that they only form the starting-point as it were for further states of contradiction. And the same is more or less true of the second type of conflict already adverted to. All these, in artistic compositions of really profound significance, are unable to remain in such forms of opposition as we have hitherto discussed. Such disturbances and conflicting elements merely substantiate the opportune moment, out of which the true and essential forces of spiritual life will clash together in opposition and contend for the mastery. That which is spiritual can only be set in activity by virtue of spirit. Consequently the oppositions of Spirit can only win reality in actual human deed, can only thus manifest themselves in their true character. The position we have arrived at, then, is this. We have on one hand a difficulty, an obstacle, a violation effected through something human life has carried out in action. We have on the other a violation of interests and forces intrinsically just and right. By treating these two forms of determination in close juxtaposition we, for the first time, are able to gauge the full depth of this last type of collision.
