What are the motifs in Consilience: The Unity of Knowledge by Edward O. Wilson?

Biology is a recurring idea in the narrative. Biology can enhance our view of the world that gains a different perspective when we unveil the manner in which it classifies life on earth, gaining a theoretical structure through the Darwinian theory of evolution. The same pattern that exists in biology involves causal events that are part of biological organization that are also applicable to life. Species not only exist in real life. They are also part of real science.
