“A distinction can always be made between weapons and tools on the basis of their usage (destroying people or producing goods). But although this extrinsic distinction explains certain secondary adaptations of a technical object, it does not preclude a general convertibility between the two groups, to the extent that it seems very difficult to propose an intrinsic difference between weapons and tools. . . . And yet we have the feeling that there are many internal differences, even if they are not intrinsic, in other words, logical or conceptual, and even if they remain approximate. At first approximation, weapons have a privileged relation with projection. Anything that throws or is thrown is fundamentally a weapon, and propulsion is its essential moment.” – Gilles Deleuze and Félix Guattari, A Thousand Plateaus (trans. Brian Massumi)
