The background of the argument Joris Vlieghe develops in this article is the idea, proposed by neopragmatic scholars, that a way of aptly dealing with the societal issues that have come about in the wake of a global ecological crisis consists of engaging in practices of study. This involves "thinking," a concept that needs to be reconsidered from an educational perspective. Hence the article turns to John Dewey's classical pragmatic account of thinking, so as to show that this Deweyan approach could be enriched by reading it together with Giorgio Agamben's reflections on this matter. This allows for rendering with greater accuracy certain aspects of thinking that unearth its properly educational meaning: that thinking is necessarily a collective endeavor that is driven by an interruption of our habitual ways of living together with a view toward envisaging truly alternative futures. Thinking is a risky experience in which the foundational subject disappears. Such a view allows, furthermore, for the reconceptualization of thinking in a posthumanist key.
