The article examines the distinction between the state of emergency and the normal state and an inherent undecidability at the base of the distinction. We argue that states of emergency arise from strategic sovereign decisions to divide visible from invisible, enemy from ally, underground economy from above-ground, illegitimate war from legitimate war. The capacity to so divide is manifested, for instance, in the technology of air raid sirens in a way that indicates the momentum of the technicity that covertly underlies sovereign power. The article, furthermore, shows how the distinction between the visible and the invisible can serve as a mystification, perpetuating the state of emergency by disguising the intrinsic connection between the two domains

The study of similarity is fundamental to biological inquiry. Many homology concepts have been formulated that function successfully to explain similarity in their native domains, but fail to provide an overarching account applicable to variably interconnected and independent areas of biological research despite the monistic standpoint from which they originate. The use of multiple, explicitly articulated homology concepts, applicable at different levels of the biological hierarchy, allows a more thorough investigation of the nature of biological similarity. Responsible epistemological pluralism as advocated herein is generative of fruitful and innovative biological research, and is appropriate given the metaphysical pluralism that underpins all of biology.

The "usual story" regarding molecular chemistry is that it is roughly an application of quantum mechanics. That is to say, quantum mechanics supplies everything necessary and sufficient, both ontologically and epistemologically, to reduce molecular chemistry to quantum mechanics. This is a reductive story, to be sure, but a key explanatory element of molecular chemistry, namely molecular structure, is absent from the quantum realm. On the other hand, typical characterizations of emergence, such as the unpredictability or inexplicability of molecular structure based on quantum mechanics, do not characterize the relationship between molecular chemistry and quantum mechanics well either. A different scheme for characterizing reduction and emergence is proposed that accommodates the relationship between quantum mechanics and molecular chemistry and some initial objections to the scheme are considered.
