Deleuze's interpretationsDeleuze's studies of individual philosophers and artists are purposely heterodox. In Nietzsche and Philosophy, for example, Deleuze claims that Nietzsche's On the Genealogy of Morality is an attempt to rewrite Kant's Critique of Pure Reason, even though Nietzsche nowhere mentions the First Critique in the Genealogy, and the Genealogy's moral topics are far removed from the epistemological focus of Kant's book. Likewise, Deleuze claims that univocity is the organizing principle of Spinoza's philosophy, despite the total absence of the term from any of Spinoza's works. Deleuze once famously described his method of interpreting philosophers as "buggery (enculage)", as sneaking behind an author and producing an offspring which is recognizably his, yet also monstrous and different.
The various monographs thus are not attempts to present what Nietzsche or Spinoza strictly intended, but re-stagings of their ideas in different and unexpected ways. Deleuze's peculiar readings aim to enact the creativity he believes is the acme of philosophical practice. A parallel in painting Deleuze points to is Francis Bacon's Study after Velázquez—it is quite beside the point to say that Bacon "gets Velasquez wrong". Similar considerations apply, in Deleuze's view, to his own uses of mathematical and scientific terms, pace critics such as Alan Sokal: "I'm not saying that Resnais and Prigogine, or Godard and Thom, are doing the same thing. I'm pointing out, rather, that there are remarkable similarities between scientific creators of functions and cinematic creators of images. And the same goes for philosophical concepts, since there are distinct concepts of these spaces."
