If we are to include the outer and the inner struggle in a conception more definite than that of conflict in general, we must employ some such phrase as 'spiritual force.' This will mean whatever forces act in the human spirit, whether good or evil, whether personal passion or impersonal principle; doubts, desires, scruples, ideas-whatever can animate, shake, possess, and drive a man's soul. [19]In a Shakespearean tragedy some such forces are shown in conflict.

A total reverse of fortune, coming unawares upon a man who 'stood in high degree,' happy and apparently secure,-such was the tragic fact to the mediaeval mind. It appealed strongly to common human sympathy and pity; it startled also another feeling, that of fear. It frightened men and awed them. It made them feel that man is blind and helpless, the plaything of an inscrutable power, called by the name of Fortune or some other name,-a power which appears to smile on him for a little, and then on a sudden strikes him down in his pride.

The calamities of tragedy do not simply happen, nor are they sent; they proceed mainly from actions, and those the actions of men.We see a number of human beings placed in certain circumstances; and we see, arising from the co-operation of their characters in these circumstances, certain actions. These actions beget others, and these others beget others again, until this series of inter-connected deeds leads by an apparently inevitable sequence to a catastrophe.

The story depicts also the troubled part of the hero's life which precedes and leads up to his death; and an instantaneous death occurring by 'accident' in the midst of prosperity would not suffice for it. It is, in fact, essentially a tale of suffering and calamity conducting to death.

The centre of the tragedy, therefore, may be said with equal truth to lie in action issuing from character, or in character issuing in action.

Research, though toilsome, is easy; imagination, though delightful, is difficult.

Macbeth's deed is done in horror, and without the faintest desire or sense of glory- done, one may almost say, as if it were an appalling duty; the instant it is finished, its futility is revealed to Macbeth as clearly as its vileness had been revealed beforehand
