a quote from a thousand plateaus

If the writer is a sorcerer, it is because writing is a becoming, writing is traversed by strange becomings that are not becomings-writer,  but becomings-rat, becomings-insect, becomings-wolf, etc. We will have to explain why. Many suicides by writers are explained by these unnatural participations, these unnatural nuptials. Writers are sorcerers because they experience the animal as the only population before which they are responsible in principle. The German preromantic Karl Philipp Mortiz feels responsible not for the calves that die but before the calves that die and give him the incredible feeling of an unknown Nature--affect. (240)
