There is renewed interest in what can be called an "experimentist" approach to education research. The claim is that if researchers would focus on experiments and "evidence-based" policies and practices, irreversible progress in education can be achieved. This experimentist approach cannot provide the understanding of knowledge and human beings needed for meaningful progress in education. Lacking is adequate appreciation for the role of theory, particularly ethical and other philosophical theory. We especially need a theory of our human condition and a keen awareness for how some conceptions of scientific work can influence, and distort, our conceptions of human beings and worthwhile lives. As paradoxical as it might seem at first, to move ahead in education and our service to persons' welfare, we need to look backward to revisit old truths. (Contains 8 notes.)
