Why do humans fight each other

Author's name: Bertrand Russell Publisher: Al-Takween for Publishing and Distribution Year of publication: 2024 Literary classification: Philosophy and Thought Brief about the book: Why do humans fight? Is it because they love fighting? Or is fighting an instinct or a nature in the human soul? And is fighting an evil that must be endured? Is it a defense of existence? Or an attempt to attack others and seize their possessions? Are there cultural and civilizational factors that make a group of humans fight another group or groups? Or is it sufficient to read economic and geopolitical factors to explain the fighting and conflict among humans?
