superfluous task of depriving human experience of all significance. Left to themselves, the facts do not speak; left to themselves they do not exist, not really, since for all practical purposes there is no fact until some one affirms it. The least the historian can do with any historical fact is to select and affirm it. To select and affirm even the simplest complex of facts is to give them a certain place in a certain pattern of ideas, and this alone is sufficient to give them a special meaning. However "hard" or "cold" they may be, historical facts are after all not material substances which, like bricks or scantlings, possess definite shape and clear, persistent outline. To set forth historical facts is not comparable to dumping a barrow of bricks. A brick retains its form and pressure wherever placed; but the form and substance of historical facts, having a negotiable existence only in literary discourse, vary with the words employed to convey them. Since history is not part of the external material world, but an imaginative reconstruction of vanished events, its form and substance are inseparable: in the realm of literary discourse substance, being an idea, is form; and form, conveying the idea, is substance. It is thus not the undiscriminated fact, but the perceiving mind of the historian that speaks: the special meaning which the facts are made to convey emerges from the substance-form which the historian employs to recreate imaginatively a series of events not present to
