Without Diversity: Singularity, Nothingness and Infinity

Plotinus called it the One; Parmenides, Being; Śaṅkara, nirguna Brahman; Heidegger, das Nichts; Maimonides and the Kabbalists, Ein Sof; Pseudo-Dionysius, the divine darkness beyond all attribution. This appendix argues that these are three relational presentations of one structural condition, the state without internal distinction that the book's main text establishes as the terminus of explanation and time, individuated by which contrast each tradition takes as salient. A tradition that begins from the world's plurality and asks what underlies the many meets the condition as unity. A tradition that begins from being and seeks its limit meets it as nothing. A tradition that begins from finitude and seeks the boundless meets it as the infinite. The appendix derives why exactly these three. Multiplicity, existence, and boundedness are the three modes any differentiated field must exhibit, so the negation of each is a structurally available doorway to the same room, with immutability and simplicity as further doorways the classical theological traditions opened. The engagement is textual throughout. Each tradition is met at its most disciplined formulation, and the appendix's most demanding exchange answers the specialist who objects that these ultimates are described as plenitude, supreme fullness, so that reading them as zero internal distinction inverts their sense. Two worked cases show the traditions performing the appendix's own move. Śaṅkara reads the scriptural definition of Brahman as reality, knowledge, and infinity as a disciplined battery of negations, each term cancelling a limitation while ascribing no property. And the Kabbalistic corpus houses its fullness carefully in the sefirot, the differentiated manifestations, while keeping Ein Sof itself beyond all attribution. The fullness belongs to the manifest; the terminus-concepts are kept apophatically bare by the traditions themselves. What the appendix diagnoses, with one consistent vocabulary, is the productive overlay each tradition adds: emanation, divine self-contraction, cosmic appearance, narratives that attribute to the distinction-free condition a generative role it has no features to perform. The three descriptions are finally recast as three patterns of descriptive failure, each tracing the same limit where predication gives out. The appendix adds no new premise to the book. Its contribution is the cross-tradition map, allowing a reader fluent in any one tradition to recognise the structural identity of its central concept with the others', and to see what the book's arguments imply for each. This paper is Appendix A of Dyology: On Diversity and Equality; it adds no premise to the book, and readers fluent in any one tradition will find the main text's arguments mapped onto theirs.
