A good part of the second part tells of Robinson's absence from the island, and concludes with trips through China and Russia in which the protagonist of Defoe comes into contact with peoples and customs very different from those presented in the first and lives amazing experiences like being chased by a pack of wolves or being attacked by a bear. However, social organization, one of the issues that has most contributed to giving importance to the novel, becomes one of the central issues, along with the themes of colonialism, the relationship between peoples with customs that clash or the consideration of culture, technology and science as double-edged weapons since they do not always lead to greater happiness.
