be content with what we at present know, is, for the most part, to shut our ears against conviction; since, from the very gradual character of our education, we must continually forget, and emancipate ourselves from, knowledge previously acquired; we must set aside old notions and embrace fresh ones; and, as we learn, we must be daily unlearning something which it has cost us no small labour and anxiety to acquire. And this difficulty attaches itself more closely to an age in which progress has gained a strong ascendency over prejudice, and in which persons and things are, day by day, finding their real level, in lieu of their conventional value. The same principles which have swept away traditional abuses, and which are making rapid havoc among the revenues of sinecurists, and stripping the thin, tawdry veil from attractive superstitions, are working as actively in literature as in society. The credulity of one writer, or the partiality of another, finds as powerful a touchstone and as wholesome a chastisement in the healthy scepticism of a temperate class of antagonists, as the dreams of conservatism, or the impostures of pluralist sinecures in the Church. History and tradition, whether of ancient or comparatively recent times, are subjected to very different handling from that which the indulgence or credulity of former ages could allow. Mere statements are jealously watched, and the motives of the writer form as important an ingredient in the analysis of his history, as the facts he records. Probability is a powerful and troublesome test; and it is by this troublesome standard that a large portion of historical evidence is sifted. Consistency is no less pertinacious and exacting in its demands. In brief, to write a history, we must know more than mere facts. Human nature, viewed under an induction of extended experience, is the best help to the criticism of human history. Historical characters can only be estimated by the standard which human experience, wheth
