“Reflective thinking is always more or less troublesome because it involves overcoming the inertia that inclines one to accept suggestions at their face value; it involves willingness to endure a condition of mental unrest and disturbance.”
— John DeweyHow We Think (1910), Chapter 1, What Is Thought?

Commentary

Dewey identifies a psychological difficulty at the centre of critical inquiry: uncertainty is uncomfortable, and people often prefer a quick explanation to the effort required to test it. An appealing claim can relieve doubt before sufficient evidence has been gathered. Reflective thought requires resisting this temptation.

The passage does not celebrate uncertainty for its own sake. Doubt is productive when it motivates further investigation. A person who remains uncertain but refuses to seek evidence has not completed the task of inquiry. Conversely, someone who reaches a conclusion quickly may have reasoned well if the available evidence warrants it. Dewey's concern is with the quality of the process rather than with delay as an end in itself.

This argument has particular relevance to public debate and democratic decision-making. Citizens encounter confident claims, emotionally compelling narratives, and assertions that reinforce existing beliefs. The willingness to suspend judgment can create space for checking sources, considering alternative explanations, and distinguishing evidence from assumption.

In education, the passage supports environments in which questions and provisional answers are treated as legitimate parts of learning. Students should not be encouraged to mistake uncertainty for failure. They should learn how to investigate uncertainty systematically and how to revise a conclusion without treating revision as a personal defeat.
