Throughout the history of mankind, providence has compelled man to study the world around him. Man must perceive the world around him simply in order to exist. Man must discover the worlds that surround him in order to improve his situation, to sustain the increasing population, to feed and clothe it. Man must evolve, develop science in order to know how to take advantage of nature for his own benefit. Without science, humanity would have been unable to survive and would remain at the level of no more than a primitive clan to this day. Man must attain such a state where he is master of his own fate, and nature will not allow him to remain in his beastly degree. Nature will force him to actively participate in the leadership of the world.
