This strong connection between thoughts, language, and tools, each of which is impossible without the other, shows that they must have developed at the same time. How this development took place, we can only conjecture. Undoubtedly it was a change in the circumstances of life that changed men from our ape-like ancestors. Having migrated from the woods, the original habitat of apes, to the plain, man had to undergo an entire change of life. The difference between hands and feet must have developed then. Sociability and the ape-like hand, well adapted for grasping, had a due share in the new development. The first rough objects, such as stones or sticks, came to hand unsought, and were thrown away. This must have been repeated so often that it must have left an impression on the minds of those primitive men.
To the animal, surrounding nature is a single unit, of the details of which it is unconscious. It can not distinguish between various objects. Our primitive man, at his lowest stage, must have been at the same level of consciousness. From the great mass surrounding him, some objects (tools) come into his hands which he used in procuring his existence. These tools, being very important objects, soon were given some designation, were designated by a sound which at the same time named the particular activity. Owing to this sound, or designation, the tool and the particular kind of activity stands out from the rest of the surroundings. Man begins to analyze the world by concepts and names, self-consciousness makes its appearance, artificial objects are purposely sought and knowingly made use of while working.
This process—for it is a very slow process—marks the beginning of our becoming men. As soon as men deliberately seek and apply certain tools, we can say that these are being developed; from this stage to the manufacturing of tools, there is only one step. The first crude tools differ according to use; from the sharp stone we get the knife, the bolt, the drill, and the spear; from the stick we get the hatchet. With the further differentiation of tools, serving later for the division of labor, language and thought develop into richer and newer forms, while thought leads man to use the tools in a better way, to improve old and invent new ones.
So we see that one thing brings on the other. The practice of sociability and the application to labor are the springs in which technique, thought, tools and science have their origin and continually develop. By his labor, the primitive ape-like man has risen to real manhood. The use of tools marks the great departure that is ever more widening between men and animals.
IX. ANIMAL ORGANS AND HUMAN TOOLS.
In animal organs and human tools we have the main difference between men and animals. The animal obtains its food and subdues its enemies with its own bodily organs; man does the same thing with the aid of tools. Organ (organon) is a Greek word which also means tools. Organs are natural, adnated (grown-on) tools of the animal. Tools are the artificial organs of men. Better still, what the organ is to the animal, the hand and tool is to man. The hands and tools perform the functions that the animal must perform with its own organs. Owing to the construction of the hand to hold various tools, it becomes a general organ adapted to all kinds of work; it becomes therefore an organ that can perform a variety of functions.
With the division of these functions, a broad field of development is opened for men which animals do not know. Because the human hand can use various tools, it can combine the functions of all possible organs possessed by animals. Every animal is built and adapted to a certain definite surrounding. Man, with his tools, is adapted to all circumstances and equipped for all surroundings. The horse is built for the prairie, and the monkey is built for the forest. In the forest, the horse would be just as helpless as the monkey would be if brought to the prairie. Man, on the other hand, uses the axe in the forest, and the spade on the prairie. With his tools, man can force his way in all parts of the world and establish himself all over. While almost all animals can live in particular regions, such as supply their wants, and if taken to different regions cannot exist, man has conquered the whole world. Every animal has, as a zoölogist expressed it once, its strength by which means it maintains itself in the struggle for existence, and its weakness, owing to which it falls a prey to others and cannot multiply itself. In this sense, man has only strength and no weakness. Owing to his having tools, man is the equal of all animals. As these tools do not remain stationary, but continually improve, man grows above every animal. His tools make him master of all creation, the king of the earth.
In the animal world there is also a continuous development and perfection of organs. This development, however, is connected with the changes of the animal’s body, which makes the development of the organs infinitely slow, as dictated by biological laws. In the development of the organic world, thousands of years amount to nothing. Man, however, by transferring his organic development upon external objects has been able to free himself from the chain of biologic law. Tools can be transformed quickly, and technique makes such rapid strides that, in comparison with the development of animal organs, it must be called marvelous. Owing to this new road, man has been able, within the short period of a few thousand years, to rise above the highest animal. With the invention of these implements, man got to be a divine power, and he takes possession of the earth as his exclusive dominion. The peaceful and hitherto unhindered development of the organic world ceases to develop according to the Darwinian theory. It is man that acts as breeder, tamer, cultivator; and it is man that does the weeding. It is man that changes the entire environment, making the further forms of plants and animals suit his aim and will.
With the origin of tools, further changes in the human body cease. The human organs remain what they were, with the exception of the brain. The human brain had to develop together with tools; and, in fact, we see that the difference between the higher and lower races of mankind consists mainly in the contents of their brains. But even the development of this organ had to stop at a certain stage. Since the beginning of civilization, the functions of the brain are ever more taken away by some artificial means; science is treasured up in books. Our reasoning faculty of today is not much better than the one possessed by the Greeks, Romans or even the Teutons, but our knowledge has grown immensely, and this is greatly due to the fact that the mental organ was unburdened by its substitutes, the books.
Having learned the difference between men and animals, let us now again consider how they are affected by the struggle for existence. That this struggle is the cause of perfection and the weeding out of the imperfect, can not be denied. In this struggle the animals become ever more perfect. Here, however, it is necessary to be more precise in expression and in observation of what perfection consists. In being so, we can no longer say that animals as a whole struggle and become perfected. Animals struggle and compete by means of their particular organs. Lions do not carry on the struggle by means of their tails; hares do not rely on their eyes; nor do the falcons succeed by means of their beaks. Lions carry on the struggle by means of their saltatory (leaping) muscles and their teeth; hares rely upon their paws and ears, and falcons succeed on account of their eyes and wings. If now we ask what is it that struggles and what competes? the answer is, the organs struggle. The muscles and teeth of the lion, the paws and ears of the hare, and the eyes and wings of the falcon carry on the struggle. It is in this struggle that the organs become perfected. The animal as a whole depends upon these organs and shares their fate.
