An historical theory of intelligence

This article consists of three parts. First, ‘The past’ defines physical and verbal intelligence and maintains that intelligence, after centuries of insignificance, rose to prominence in modern times as a consequence of the increase in intelligence targets and the growth of verbal intelligence. Second, ‘The present’ explains that the function of intelligence is to optimize resources, that it is but an auxiliary element in war, and that it is necessary to the defense but is only contingent to the offense. Third, ‘The future’ articulates intelligence's two perpetual insoluble problems: foretelling everything and getting leaders to accept information that they do not like.
