ABSTRACT
This chapter draws on the most important developments in ethical, ethological, deconstructive, and ontological research to update and strengthen the antispeciesist account by paying heed to better attention to the experiences of animals and to philosophical advances that have further challenged humanism. Roberto Marchesini's posthumanist antispeciesism is one that seeks to build on the thought about speciesism and posthumanism to bring those two approaches into productive diffraction. It argues that both consequentialism and deontology are ethical systems that were developed in the heyday of Western philosophical humanism and that as such it is difficult to disentangle them from that lineage. Humanism is the negation of animality: in the human being confining animality to mere corporeity, in the nonhuman characterizing it in mechanomorphic terms. Humanism is founded on the type of subjectivity that attributes to the human being the status of demiurge of its own destiny.
