In this chapter I will lay out two main aspects of the West’s 21st-century critical monism (CM) which in our own return of the Controversy must be, as Sandkaulen said characterized Jacobi’s original effort, contradicted and not refuted by the neo-Jacobian position. The first is the [arguably incoherent, when taken as an account of the entirety of nature] ontology of necessity ostensibly contained in big bang cosmology and underpinning the entire Western picture of nature as such, and the second is the accelerating human conversion and vanishing of the living (and even some of the nonliving) layers of the real external world. While I will intersperse some neo-Jacobian responses in this chapter, I will reserve most of my [still-nascent] neo-Jacobian position for the next (and last) one. These final two chapters are not intended to be exhaustive accounts of the twenty-first century return of the Controversy. Further refinement and exploration of why and how the Controversy has returned in the contemporary period in a specifically environmental key will hopefully unfold both in responses from others to this work, and in my own further future work on the neo-Jacobian position in what will hopefully form the topic of a sequel volume to this one.
