The article traces Nietzsche’s references to insects in his published and unpublished writings against the backdrop of his study of the entomological research of his time (esp. through his reading of Alfred Espinas’s Die thierischen Gesellschaften). The first part of the article explores how Nietzsche’s entomology allows us to add a posthumanist perspective to the more familiar poststructuralist readings of Nietzsche, as the entomological research he consulted offered him a model for understanding how rudimentary processes can lead to the formation (...) of structures and higher organizations with emergent properties. The second part of the article revisits Nietzsche’s conceptions of the will and the will to power against the backdrop of his references to insect sociality and the influence of Wilhelm Wundt. It shows that Nietzsche’s deconstruction of the will as an umbrella concept and his will to power are attempts to model the emergence of complex edifices from simple operations under which physical, psychological, and social phenomena must be thought to arise. The article concludes with a reflection of the social and political relevance of what Nietzsche identifies as modernity’s “disgregation of the will.”. (shrink)
