Whoever tries to discover the internal stimulus, the constructive idea, the lyrical motive, which led Shakespeare to convert the Chronicles of Holinshed and the Lives of Plutarch into dramatic form, when his possession of the epic ideal and nostalgia for the past have been excluded, finds nothing save an interest in and an affection for practical achievement, for action attentively followed, in its cunning and audacity, in the obstacles that it meets, in the discomfitures, the triumphs, the various attitudes of the different temperaments and characters of men. This interest, finding its most suitable material in political and warlike conflicts, was naturally attracted to history and to that especial form of it, which was nearest to the soul and to the culture of the poet of his people and of his time, English and Roman history. This material had already been brought to the theatre by other writers and was in this way introduced to the attention and used by the new poet. A psychological origin of this sort explains the vigour of the representations, which Shakespeare derived from history, incomprehensible, if as philologists maintain, he had simply set himself to cultivate, a "style" that was demanded in the theatre and known as _chronicle plays,_ or had there set himself a merely technical task, with a view to attaining dexterity. That psychological interest, too, in so far as separated from a supreme end or ideal, towards which actions tend, or rather in so far as it remains uncertain and vague in this respect, limiting itself to questions of loss or gain, of success or failure, of living or dying, is not a qualitative, but a _formal_ interest. It can also be called political, if you will, but political in the sense of Machiavelli and the Renaissance, in so far as politics are considered for themselves, and therefore only formally. Hence the impression caused by the historical plays of Shakespeare, of being now "a gallery of portraits," now "a series of personal experiences," which the poet is supposed to have achieved in imagination.
