Abstract To formulate a plan of action for bringing about a decisive and reasonably stable end to an injustice, it is helpful to understand the factors and conditions that critically make the difference in causing that injustice. This intuitively seems correct regarding active and ongoing problems. But what precisely is involved in this kind of explanatory endeavor, and what is its role in practical efforts to confront existing wrongs? This paper offers an introduction to etiology of injustice , which is the study and explanation of the operative causation of injustices. Drawing on insights from the philosophy of social transformation, causation, and remedial justice, I sketch a conceptual framework for understanding and undertaking the task of etiology of injustice and outline the contours of the etiological tradition of thought.
