2 February 1874 – 8 February 1874

I am still reading the “Origines du Christianisme” by Ernest Havet. I like the book and I dislike it. I like it for its independence and courage; I dislike it for the insufficiency of its fundamental ideas, and the imperfection of its categories. The author, for instance, has no clear idea of religion; and his philosophy of history is superficial. He is a Jacobin. “The Republic and Free Thought”—he cannot get beyond that. This curt and narrow school of opinion is the refuge of men of independent mind, who have been scandalized by the colossal fraud of ultramontanism; but it leads rather to cursing history than to understanding it. It is the criticism of the eighteenth century, of which the general result is purely negative. But Voltairianism is only the half of the philosophic mind. Hegel frees thought in a very different way. Havet, too, makes another mistake. He regards Christianity as synonymous with Roman Catholicism and with the church. I know very well that the Roman Church does the same, and that with her the assimilation is a matter of sound tactics; but scientifically it is inexact. We ought not even to identify Christianity with the gospel, nor the gospel with religion in general. It is the business of critical precision to clear away these perpetual confusions in which Christian practice and Christian preaching abound. To disentangle ideas, to distinguish and limit them, to fit them into their true place and order, is the first duty of science whenever it lays hands upon such chaotic and complex things as manners, idioms, or beliefs. Entanglement is the condition of life; order and clearness are the signs of serious and successful thought. Formerly it was the ideas of nature which were a tissue of errors and incoherent fancies; now it is the turn of moral and psychological ideas. The best issue from the present Babel would be the formation or the sketching out of a truly scientific science of man.
