The first step which visibly brought mankind away from the animal world was that which led to the first invention. The invention itself owes its origin to the ruses and stratagems which man employed to assist him in the struggle with other creatures for his existence and often to provide him with the only means he could adopt to achieve success in the struggle. Those first very crude inventions cannot be attributed to the individual; for the subsequent observer, that is to say the modern observer, recognizes them only as collective phenomena. Certain tricks and skilful tactics which can be observed in use among the animals strike the eye of the observer as established facts which may be seen everywhere; and man is no longer in a position to discover or explain their primary cause and so he contents himself with calling such phenomena 'instinctive.'

This is more easily understood and more easy to believe in the case of man. His first skilled tactics in the struggle with the rest of the animals undoubtedly originated in his management of creatures which possessed special capabilities.

There can be no doubt that personality was then the sole factor in all decisions and achievements, which were afterwards taken over by the whole of humanity as a matter of course. An exact exemplification of this may be found in those fundamental military principles which have now become the basis of all strategy in war. Originally they sprang from the brain of a single individual and in the course of many years, maybe even thousands of years, they were accepted all round as a matter of course and this gained universal validity.

Man completed his first discovery by making a second. Among other things he learned how to master other living beings and make them serve him in his struggle for existence. And thus began the real inventive activity of mankind, as it is now visible before our eyes. Those material inventions, beginning with the use of stones as weapons, which led to the domestication of animals, the production of fire by artificial means, down to the marvellous inventions of our own days, show clearly that an individual was the originator in each case. The nearer we come to our own time and the more important and revolutionary the inventions become, the more clearly do we recognize the truth of that statement. All the material inventions which we see around us have been produced by the creative powers and capabilities of individuals. And all these

inventions help man to raise himself higher and higher above the animal world and to separate himself from that world in an absolutely definite way. Hence they serve to elevate the human species and continually to promote its progress. And what the most primitive artifice once did for man in his struggle for existence, as he went hunting through the primeval forest, that same sort of assistance is rendered him to-day in the form of marvellous scientific inventions which help him in the present day struggle for life and to forge weapons for future struggles. In their final consequences all human thought and invention help man in his life-struggle on this planet, even though the so-called practical utility of an invention, a discovery or a profound scientific theory, may not be evident at first sight. Everything contributes to raise man

Hence all inventions are the result of the creative faculty of the individual. And all such individuals, whether they have willed it or not, are the benefactors of mankind, both great and small. Through their work millions and indeed billions of human beings have been provided with means and resources which facilitate their struggle for existence.
