Innate and Acquired Drives -- The Conception that Whatever Humans Achieved Derives from the Unrestricted Capacity of Their Brain to Acquire Drives -- Enhancer Regulation: A Neurochemical Approach to the Innate and Acquired Drives -- Approaching Old Problems From A New Angle -- Theoretical Aspects of the Enhancer Regulation Approach -- Conclusion.The main message of this monograph is that the appearance of the mammalian brain with the ability to acquire drives ensured the development of social life, and eventually led to the evolution of the human society. This most sophisticated form of organized life on earth is still in the trial and error phase of its development. It seeks to outgrow the myth-directed era of its history and come to its final state, the ration-directed human society.
