This paper examines the links between philosophy and economics in John Dewey's thought and underlines the contribution of the social philosophy by which the pragmatist philosopher constructs those links. We show that his social philosophy, that he considered as contributing to the resolution of social issues, is the ground for a fundamental critique of the institutions and of the economic science of his times. Dewey advocates a reconstruction of social philosophy which connects economics, politics and ethics and which demonstrates how the economic process should contribute to the development of a democratic society. It is from this perspective that the philosopher simultaneously criticises individualism as a social theory and as an organising principle of economic life, substituting in its place a philosophy of experience and an ethics of democracy based on the social control of economic forces
