How did John Dewey develop instrumentalism from pragmatism?

John Dewey developed instrumentalism by reformulating the core tenets of pragmatism, integrating the logical rigor of Charles Sanders Peirce with the humanistic focus of William James.1

Dewey’s approach was shaped by his background in psychology and education, leading him to view ideas as "instruments" or tools for action. He argued that knowledge is not a static reflection of reality but the result of active inquiry into the correlations between events. In his framework:21

• Ideas as Plans: Ideas function as hypotheses and plans of action used to predict future consequences and resolve problematic situations.21
• Experimental Inquiry: He emphasized that all inquiry—whether scientific, social, or moral—follows a consistent method of testing and revision to achieve "warranted assertions" rather than absolute truths.21
• Human Benefit: The ultimate purpose of this inquiry is to empower individuals to direct natural and social processes toward human benefit, with "growth" serving as the primary moral end.21

By synthesizing these elements, Dewey created a coherent theory that applied the scientific method to both practical problem-solving and the broader ethical development of a democratic society.1
