Charles darwin principle of antithesis

Later, such reactions, which could be observed by other members of the group, increasingly become more distinctive and exaggerated in order to fulfill a primarily socially communicative function. Respiration is partly voluntary, but mainly reflex, Charles darwin principle of antithesis is performed in the most natural and best manner without the interference of the will.

There is a very elaborate discussion on blushing. These are actions that have all the appearance of being guided by intelligence and instigated by will in an animal, the recognized organ of whose intelligence and will has been removed.

Notably we have here not merely contractions of muscles, but combined and harmonized contractions in due sequence for a special purpose. At the same time from habit he closely 46 depresses his ears, so as to protect them from being bitten, as if he were fighting with another horse.

Such habitual movements are often, or generally inherited; and they then differ but little from reflex actions.

But when a man or horse starts, his heart beats wildly against his ribs, and here it may be truly said we have an organ which has never been under the control of the will, partaking in the general reflex movements of the body.

We will now consider how the principle of antithesis in expression has arisen. Thus reflex actions, when once gained for one purpose, might afterwards be modified independently of the will or habit, so as to serve for some distinct purpose.

Norfolk, in speaking of Cardinal Wolsey, says -- " Some strange commotion Is in his brain; he bites his lip and starts; Stops on a sudden, looks upon the ground, Then, lays his finger on his temple: This is quite involuntary, and does not occur later in life, but the whole mechanism by which it is produced has been traced out, and it is found that it is a provision to prevent injury to the delicate vessels of the eyes by the increased flow of blood to the head during violent screaming.

It has been an objection to Mr. Sometimes it was repeated incessantly for an hour or more. They are explicable, as far as I can see, solely from being in complete opposition or antithesis to the attitude and movements which, from intelligible causes, are assumed when a dog intends to fight, and which consequently are expressive of anger.

A book review printed in the January number of the Quarterly Journal of Science. I request the reader to look at the four accompanying sketches, which have been given in order to recall vividly the appearance of a dog under these two states of mind.

Now when a directly opposite state of mind is induced, there is a strong and involuntary tendency to the performance of movements of a directly opposite nature, though these are of no use; and such movements are in some cases highly expressive. Having referred to the act of sucking, I may add that this complex movement, as well as the alternate protrusion of the fore-feet, are reflex actions; for they are performed if a finger moistened with milk is placed in the mouth of a puppy, the front part of whose brain has been removed.

It is probable that sneezing and coughing were originally acquired by the habit of expelling, as violently as possible, any irritating particle from the sensitive air-passages. I give these assertions on the authority of Dr.

Eager to stress the differences between human and animal communication, Bell wrote: He who will attend to the starting of his horse, when tired and fresh, will perceive how perfect is the gradation from a mere glance at some unexpected object, with a momentary doubt whether it is dangerous, to a jump so rapid and violent, that the animal probably could not voluntarily whirl round in so rapid a manner.

After his initial correspondence with the psychiatrist James Crichton-Browne [12] Darwin set aside his material concerning emotional expression in order to complete The Descent of Manwhich covered human ancestry and sexual selection. If this foot be cut off, it cannot thus act. It is well known that cats dislike wetting their feet, owing, it is probable, to their having aboriginally inhabited the dry country of Egypt; and when they wet their feet they shake them violently.

It has been thought by some to be a special endowment for the purpose of expressing modesty or shame, but Mr. Nevertheless it is more than doubtful, as we shall immediately see, whether any of the cases which come under our present head of antithesis, have thus originated.

Jackals, fennecs, and other allied animals in the Zoological Gardens, treat their straw in this manner; but it is a rather odd circumstance that the keepers, after observing for some months, have never seen the wolves thus behave. A good illustration of this fact has already been given in the Introduction, namely, in the grotesque movements of a young and eager billiard- 65 -player, whilst watching the course of his ball.

Now when horses in their stalls are about to be fed and are eager for their corn, they paw the pavement or the straw. Now I have noticed scores of times that when two strange dogs meet on an open road, the one which first sees the other, though at the distance of one or two hundred yards, after the first glance always lowers its head, generally crouches a little, or even lies down; that is, he takes the proper attitude for concealing himself and for making a rush or spring, although the road is quite open and the distance great.
