 Be that as it may, in What is Philosophy? Deleuze and Guattari vigorously deny that philosophy is needed to help science think about its own presuppositions (“no one needs philosophy to reflect on anything” [WP 6]). Instead, they emphasize the complementary nature of the two. First, they point out a number of similarities between philosophy and science: both are approaches to “chaos” that attempt to bring order to it, both are creative modes of thought, and both are complementary to each other, as well as to a third mode of creative thought, art.
