Abstract reasoning is among the main powers of the human intellect. It is more subjective than concrete reasoning because it is rather a product of mental work than of direct experience. The inductive logic, metaphorical approach and interpretational abilities are arts of their own. With increasing the proportion of abstraction, however, reasoning becomes more and more subjective, nonconcrete and unrealistic. The greater the idealization is the more one-sided it becomes. The proclivity of science to bias and ethnocentrism increases with the scope of the generalizations it employs. For that reason nonfigurative science is by necessity ethically biased in the same way as art and religion are.
