# The Psychology of Thinking explained — Human Nature and Conduct

> Chapter companion for Human Nature and Conduct by John Dewey.

## What happens

Dewey argues that moral knowledge is not derived from a separate, non-natural faculty like conscience or pure reason, but emerges from the interplay of habit and impulse in response to problematic situations. Thinking arises when habitual action is blocked, releasing impulse that drives inquiry, observation, and planning. Knowledge is thus a natural, acquired result of biological and social processes, continuous with other forms of conduct.

## Themes in this chapter

### Habit and Custom as the Foundation of Conduct

Dewey explains that knowledge and judgment are rooted in habits, which are disrupted by obstacles, leading to reflective thought.

### Impulse and Intelligence as Agents of Change

Impulse is released when habits are blocked, initiating inquiry and the reconstruction of conduct.

### Critique of Traditional Morality and Dualisms

Dewey rejects the separation of moral knowledge from natural human processes, opposing intuitionist theories of conscience.

## Character check-ins

### Aristotle

Cited as asserting that the faculty of pure knowing enters a man from without, representing the view Dewey criticizes.

## Key lines

> The reason a baby can know little and an experienced adult know much when confronting the same things is not because the latter has a 'mind' which the former has not, but because one has already formed habits which the other has still to acquire.

Differences in knowledge between a baby and an adult are due to accumulated habits, not an innate mental faculty.

_Dewey emphasizes that knowledge is built through habit formation, not through a separate mind or consciousness._

> The scientific man and the philosopher like the carpenter, the physician and politician know with their habits not with their 'consciousness.'

Experts in any field rely on their ingrained habits, not on a detached consciousness, to perform their work.

_Dewey argues that all knowing is habitual and embodied, not the product of a pure intellect._
