MECHANISM IN THOUGHT AND MORALS. An Address delivered before the Phi Beta Kappa Society of Harvard University, June 29, 1870. With Notes and Afterthoughts. By Oliver Wendell Holmes. Boston: James R. Osgood & Co. 1871.

Dr. Holmes is a Benvenuto Cellini in literature, and everything he produces is of precious metal, skilfully enchased, and adorned with gems of art. The present address is no exception to the general rule, but rather an unusually good illustration of it. It is a remarkably curious piece of work, containing many interesting facts and speculations derived from the author's scientific studies on the mechanism of the brain. There is nothing in it positively affirmed which is necessarily materialistic, as far as we can see; rather, we should say that its doctrine stands on one side of both materialism and spiritualism, and can be reconciled with either. It can be explained, if we have understood it correctly, in conformity with the Aristotelian and scholastic philosophy, in such a way as not to prejudice the truth of the distinct and spiritual nature of the soul. The author, indeed, appears more inclined to that belief than the opposite, although we are sorry to find him expressing himself in so hesitating and dubious a manner. When he passes from thought to morals, he gets out of his element, and displays a flippancy and levity which may pass very well in humorous poetry, but are out of place in treating of graver topics. His remarks on some points of Catholic doctrine are so completely at fault as to show his entire incompetency to meddle with the subject at all. His language in regard to the Council of the Vatican and Pius IX. is more like that of a pert and vulgar student of Calvinistic divinity than that of an elegant and refined Cambridge professor. "But political freedom inevitably generates a new type of religious character, as _the conclave that contemplates endowing a dotard with infallibility_ has found out, we trust, before this time" (p. 95). Dr. Holmes has apparently profited by his close observations among that class of the female population of Boston who are wont to thrust their bodies half out of their windows, and "exhaust the vocabulary, to each other's detriment." We congratulate him, and the learned Society of Phi Beta Kappa, on the choice sentence we have quoted above. We trust those Catholics who are disposed to think that we can make use of Harvard University as a place of education for our youth, will take note of this sample of the language they may expect to hear in that and similar institutions, and open their eyes to the necessity of providing some better instruction for their sons than can be had at such sources. Notwithstanding our high appreciation of Dr. Holmes's genius, and the great pleasure we have derived from his works, we regret to say that we must consider his influence on young people grievously detrimental. In virtue of a reaction from Calvinism, he has swung into an extreme of rationalism the effect of which is checked in his own person by the influence of an unusually good heart and an early religious education, but in itself is sure to overthrow all reverence, faith, and moral principle. The whole effect of this address on the minds of young men tends to a most pernicious result, and encourages them, with a kind of thoughtless gaiety, to rush forward in a career of mental and moral lawlessness.
