The truth of this, in so far as regards the limitation of the will, cannot fail to force itself upon the student of culture. It is, I venture to think, by classifying and arranging in evolutionary order the actual facts of the manifestations of mind, as seen in the development of the arts, institutions, and languages of mankind, no less than by comparative anatomy, and far more than by metaphysical speculation, that we shall arrive at a solution of the question, to what extent the mental Ego has been, to use Professor Huxley’s expression, a conscious spectator of what has passed.
I propose, therefore, with your permission, to give a few examples, by means of diagrams, of material evolution derived from the earliest phases of culture. In language and in all ideas communicated by word of mouth there is a hiatus between the limits of our knowledge and the origin of culture which can never be bridged over, but we may hold in our hand the first tool ever created by the hand of man.
It has been said that the use of speech is the distinctive quality of man. But how can we know that? We are literally surrounded by brute language. We can imitate their calls, and we find that animals will respond to our imitations of them. But who has ever seen any of the lower animals construct a tool and use it.
The conception of man, not as a tool-using but as a tool-making animal, is clear, defined, and unassailable; probably if we could trace language to its sources, we should be able to draw the same line between natural sounds employed as a medium of communication, and the created word. Thus the arts which we can study may perhaps be taken to illustrate the origin of language, which we cannot study in this phase.
The ape employs both sticks and stones as missiles and as hammers to crack the shells of nuts. But we have no evidence that he ever selects special forms for special uses. The arts therefore afford us a clearly defined starting-point for the commencement of culture.
To go in search of a particular form of stick or stone in order to apply it to a particular use would require greater effort of the will in fixing attention continuously on the matter in hand than is found to exist amongst the lower animals except in cases of instinct, which term I understand to mean an inherited congenital nervous organism which adapts the mind to the ready reception of experience of a particular kind. But this instinct does not exist in the case in question; there is no tool-making instinct: our tool has to be evolved through reason and experience, without the aid of any special organism for the purpose.
The process we have to assume therefore is that, in using stones as hammers, they would occasionally split. In using certain stratified rocks this would occur frequently, and so force itself on the attention of the creature. The creature going on hammering, it would force itself on his notice that the sharp fractured end was doing better work than before. It would be perceived that there were hard things and soft things, that the hard things split the stone, and the soft things were cut by it; and so there would grow up in the mind an association of ideas between striking hard things and splitting, and striking soft things and cutting, and also a sequence by which it would be perceived that the fracture of the stone was a necessary preliminary to the other; and in the course of many generations, during which the internal organism of the mind grew in harmony with this experience, the creature would be led to perform the motions which had been found effectual in splitting the stone before applying it to the purposes for which it was to be used.
Thus we arrive at a state of the arts in which we may suppose man to be able to construct a tool by means of a single blow. By constantly striking in the same direction, flakes would be produced; and by still further repeating the same motions, it would at last be found that by means of many blows a stone could be chipped to an edge or a point so as to form a very efficient tool.
But this continued chipping of the stone in order to produce a tool, implies a considerable mental advance upon the effort of mind necessary to construct a tool with one blow.
