Let us take up the necessity for a world outlook from the angle of the proverbial riddle (the chicken and egg riddle). Which came first: human beings or their world outlook? This is a riddle which can be easily solved by asking the question in this manner: "Which came first, theory or practice?" Human beings have gone through thousands of years of practice, or, one could say, evolution. What is known historically is that first there were some physical, anatomical, physiological changes, or, in sum, structural changes, followed by a change in function. It is not possible to explain the existence of human beings without, biologically speaking, various physiological and structural changes having taken place. One of the important changes was the development of vocal cords. For homo sapiens to stand erect on two legs, to become unique bipedal mammals, a lot of changes in their biological structure had to take place. Only once such changes were in place to a certain extent was it possible for the function itself to evolve into what we call the human, that is, to be able to use the hands consistently with the brain and thus change nature. In human social development, it is practice which had to develop to a certain level before theory could come into being and play its own directing role. Today too, without practice it is not possible to acquire a world outlook consistent with that practice. Of all the great struggles of the present era, the class struggle and the struggles for production and scientific experimentation, play the most dominant role in social development. It can be said that without waging the class struggle, it will not be possible to acquire a world outlook. Without acquiring a world outlook, it is not possible to further develop the class struggle. As regards the development of the species, it can be said with certainty that homo sapiens had no choice but to evolve. The conditions were crying out for nature to produce such a species as could not only think-in-itself and work according to habits acquired over millennia, transformed into spontaneous natural behavior, so determined by the structure and function of any organism within those conditions, but a species which could also think for others, which could abstract absence (i.e., conceptualize what is missing) in a profound way and make nature yield what was necessary for the humanization of both the social and the natural environments.
