Affect is so powerful and represents such ripe territory for study that, in its infancy, conventions of research need to be established that attend to its particular motion and shape. Masamune¿s Blade: A Proposition for Dialectic Affect Research outlines an original research method for the study of affect known as affect probes, and proposes the establishment of a new knowledge project based in affect. The book begins with a call to discursively reshape research using affect, after which the authors develop a unique conceptualization of affect, one that brings it into the realm of Frankfurt School Critical Theory. The theoretical foundation sets up the affect probe method, which involves giving participants a package of small activities that require fun, easy, and creative participation. The activities are intended both to inspire affects and to mark their presence. Strategies for analysis are outlined and a series of critical interventions are woven throughout the text to situate the ideas.
