 The most prominent example of the revivifying effect is Bergson, relatively forgotten at the time of Deleuze’s Bergsonism (1966), but now the subject of a growing philosophical literature. Of course, we cannot attribute all this interest to Deleuze’s book and to the subsequent secondary literature on Deleuze that stresses the contribution of Bergson to Deleuze’s system (as we ourselves do above on the concept of the virtual and the critique of the possible), but it is not implausible to consider the counterfactual whereby without Deleuze’s work the interest in Bergson would not be as strong as it currently is. Among the Bergson commentaries Mullarkey 1999, Guerlac 2006, Moulard-Leonard 2009, Grosz 2017, and Lundy 2018 all link the two thinkers in their works.
