# Part I: Of Man explained — Leviathan

> Chapter companion for Leviathan by Thomas Hobbes.

## What happens

Hobbes introduces his philosophical anthropology, beginning with sensation and imagination, then moving to the passions, speech, reason, and the voluntary motions that drive human action. He lays the groundwork for understanding human nature as the foundation for political philosophy.

## Themes in this chapter

### Human Nature and Passions

Hobbes systematically analyzes the origins of human thought, passion, and voluntary motion, establishing a materialist and deterministic view of human nature.

### State of Nature and Social Contract

The analysis of human passions and reason in this part sets the stage for Hobbes's later argument about the state of nature and the necessity of a social contract.

## Key lines

> There is no conception in a man's mind which hath not at first, totally or by parts, been begotten upon the organs of sense.

Every idea originates from sensory experience, either directly or through combination.

_Hobbes's empiricist and materialist theory of knowledge._

> The original of them all is that which we call sense, for there is no conception in a man's mind which hath not at first, totally or by parts, been begotten upon the organs of sense.

All thought begins with sensation; nothing in the mind comes from innate ideas.

_Hobbes rejects innate ideas, grounding all knowledge in sensory experience._
