Banaz for By many measures, our similarities to other animals far outweigh our differences from them. Nature (the impact of biology) is often contrasted with nurture (the impact of culture). Both nature and nurture continue to play important roles in politics. Not only our culture but also our biology shapes and constrains our political life. To understand the link between human nature and politics, we must take this biological influence seriously. The Political Significance of Human Nature What is the relationship between biology and politics, nature and nurture, and which is the more powerful force shaping our lives? These questions are as old as political thinking itself. Few ideas, a historian writes, have been recycled as often as the belief that the Is’ of nature must become the Ought’ of man. Banaz 2016.
