"Strayer, in Haecceities, gives us a fascinating, extended intellectual meditation on the limits of abstraction in art, and does so with such a breathtaking relentlessness, that it is unlikely that anyone could ever write a more definitive book on the subject." - Phil Jenkins, Marywood University, in: Philosophy in Review 39.2 (2019)
