The Expressions of the Emotions in Man and Animals is the title of the latest work written by Charles Darwin. This author has already gained a pretty widespread name by his two volumes on the Descent of Man, and on The Origin of Species. In all these, he advocates the theory of only one parent and progenitor, common both to man and to the animal.

Man is the offspring of the brute. The only distinction between them is that of a more perfect development. Man is a monkey perfectly developed. This developing process is no other than habit transmitted, imitation, and practice.

This theory is supposed in the volume before us—The Expressions, etc. It is, indeed, taken for granted, and Mr. Darwin merely seeks confirmatory proofs in this work. How he does so we shall see.

The reasoning of the entire volume may be summed up in the following syllogism: The expressions of the emotions in man and animals are, for the most part, similar, nay, alike. Now, this could not be so, did man not descend from the animal; therefore, man is the offspring of the brute.

Of course, he will have to admit some accidental differences in the expressions of each. But these he easily gets over by saying that in man those external expressions of the emotions are already perfected, matured, and developed, while in animals they are as yet budding, developing, and perfecting.

The principle of evolution would seem to account for all differences. The animal, by evolving its faculties in a long series of years, rises gradually to a higher species, and finally, having walked on all fours, comes to the conclusion it would be better and more sensible to use only two feet. Having looked downward for a long time, it begins to think it would be more honorable and decent to assume an upright posture. And then, grunting and howling are by no means as becoming as speaking French, or Italian, or Chinese; hence, Mr. Orang comes to the conclusion that he has been silent long enough, and that it is time that he, too, should have his say about matters.

We do not say that this is all expressed in so many words in the volume before us. Oh! no; Mr. Darwin is too adroit to do that. Like the devil, he sometimes assumes the garment of light, and puts on an appearance of virtue. His words are characterized by a tone of modesty and humility and even diffidence which is not common to that class of writers. He does not directly affirm anything; but he asks questions that contain a negative answer. He insinuates. He does not tell us man is a monkey, but he affirms that man expresses his feelings in the same manner as do these animals. Hence how explain this similarity, if they be not brothers?

We call attention to this fact. It alone can render his work dangerous to youthful or unguarded minds. We think there is little to fear that its frivolous arguments will excite anything but laughter and ridicule among men of solid erudition.

Unfortunately, the ideas embodied in this book are the creed of many enlightened persons, even, of this “progressive” age. This alone accounts for the favor and widespread circulation Darwin’s writings have acquired. Protestantism has done its work only too well. Casting off all authority in matters of faith, it has paved the way to all errors, and its theory has merely been developed by our modern materialists.

We are not disposed to deny the great labor and varied research employed in the work before us; but, we must say, seldom has it been our lot to witness such shallowness of argument, such loose connection between premises and conclusions. It will astonish the intelligent reader that so earnest a student as Mr. Darwin evidently is, could make use of logic in a manner discreditable to any tyro.
