Gulliver’s Travels

Gulliver’s Travels uses fantastical lands to critique politics and human nature. I wonder what influenced Swift’s choice of satire over pure adventure?

His admiration turns to disdain, which made me wonder how much of his perspective is shaped by his own biases. Would a different reader see his judgments differently?

The episodic nature gives each land its own theme, but I’m curious if this was a deliberate choice to emphasize the satire or if it evolved naturally during writing.
