In the Novel Things fall apart How does Okonkwo's illustrate characteristics of manhood use examples from the novel?

Masculinity is one of Okonkwo's obsessions, and he defines masculinity quite narrowly. For him, any kind of tenderness is a sign of weakness and effeminacy. Male power lies in authority and brute force. But throughout the novel, we are shown men with more sophisticated understanding of masculinity. Okonkwo's harshness drives Nwoye away from the family and into the arms of the new religion.
