stamp as, eighteen centuries ago, by Christianity, and twenty-five centuries ago, by Buddhism, when, around the Mediterranean as in Hindostan, the extreme effects of Aryan conquest and organization led to intolerable oppression, the crushing of the individual, utter despair, the whole world under the ban of a curse, with the development of metaphysics and visions, until man, in this dungeon of despondency, feeling his heart melt, conceived of abnegation, charity, tender love, gentleness, humility, human brotherhood, here in the idea of universal nothingness and there under that of the fatherhood of God.  Look around at the regulative instincts and faculties implanted in a race; in brief, the turn of mind according to which it thinks and acts at the present day; we shall find most frequently that its work is due to one of these prolonged situations, to these enveloping circumstances, to these persistent gigantic pressures brought to bear on a mass of men who, one by one, and all collectively, from one generation to another, have been unceasingly bent and fashioned by them, in Spain a crusade of eight centuries against the Mohammedans, prolonged yet longer even to the exhaustion of the nation through the expulsion of the Moors, through the spoliation of the Jews, through the establishment of the Inquisition, through the Catholic wars; in England, a political establishment of eight centuries which maintains man erect and respectful, independent and obedient, all accustomed to struggling together in a body under the sanction of law; in France, a Latin organization which, at first imposed on docile barbarians, than leveled to the ground under the universal demolition, forms itself anew under the latent workings of national instinct, developing under hereditary monarchs and ending in a sort of equalized, centralized, administrative republic under dynasties exposed to revolutions.  Such are the most efficacious among the observable causes which mold the primitive man; they are to nations what education, pursuit, condition, and abode are to individuals, and seem to comprise all, since the external forces which fashion human matter, and by which the outward acts on the inward, are comprehended in them.

There is, nevertheless, a third order of causes, for, with the forces within and without, there is the work these have already produced together, which work itself contributes toward producing the ensuing work; beside the permanent impulsion and the given environment there is the acquired momentum.  When national character and surrounding circumstances operate it is not on a tabula rasa, but on one already bearing imprints.  According as this tabula is taken at one or at another moment so is the imprint different, and this suffices to render the total effect different.  Consider, for example, two moments of a literature or of an art, French tragedy under Corneille and under Voltaire, and Greek drama under AEschylus and under Euripides, Latin poetry under Lucretius and under
