This document summarizes a review of the book "Art practice as research: Inquiry in the visual arts" by Graham Sullivan. The review provides context on arts-based research and positions Sullivan's work as arguing that art practice itself can constitute a form of research. It describes Sullivan's view that artists are already engaged in research through their studio practice of questioning and experimentation to generate knowledge. The review also summarizes Sullivan's perspective that arts-based research allows for understanding in unique ways compared to traditional social science approaches, through ambiguity and complexity rather than explanation. It positions Sullivan's work as making an important contribution to arguing that visual art is a valid way of knowing and generating knowledge.
