This chapter takes up the theory of habit developed by Félix Ravaisson (1813–1900) to consider how culture proceeds in non-human species. It argues that the biological body is the fundamental medium of meaning-making. Ravaisson takes Aristotle’s notion of habit as a second nature and extends it beyond the human polis to include the whole biological order. Habit takes the intentional ideas of organisms and embodies them in their real bodies; it is a universal power of ‘second-naturing’ that integrates matter with mind. Ravaisson’s account of habit can combine with Poinsot’s account of semiotic custom, so that the whole of organic life—its meanings and its materiality—can be understood as the locus of second-naturing. The biosemiotic Ravaissonism that emerges here makes a bold proposal: nature is not only the producer of cultures; nature is itself cultural, because its form is shaped over evolutionary time by the semiotically executed habits of organisms.

This paper examines the nature of spirit and spirituality as organic response to threat in the context of a global pandemic. Drawing from the fields of neuroscience, philosophy and theology, the author defines spirit as the biological capacity of a living organism to maintain homeostasis in response to changes in its environment. The capacity of individual human organisms to respond to changes that are perceived as threats to homeostasis with passive and active power is posited as a spirituality that is crucial for the survival of the human species. The paper represents a form of secular spirituality that is synonymous with the natural power of organic life.

AbstractBackgroundRecent studies have implicated variations in DNA methylation in the aetiology of schizophrenia. Genome-wide scans in both brain and blood report differential methylated regions (DMRs) and positions (DMPs) between patients with schizophrenia and healthy controls. Previously, we reported that DMRs where human specific methylation (hDMR) has occurred over evolutionary time are enriched for schizophrenia-associated markers (SCZ_hDMR). However, it is unknown whether these human specific DMRs show variable methylation in patients with schizophrenia.MethodsUsing publicly available data, we investigate if human specific DMRs that harbour genetic variants associated with schizophrenia are differentially methylated between cases and controls.ResultsWe find statistically significant (p < 1e-4) methylation difference in schizophrenia associated human specific DMRs (SCZ hDMR) between brain samples of cases and controls. However, we fail to find evidence of similar differences in methylation in blood samples.ConclusionRegions that are evolutionarily important for human species and that are associated with schizophrenia, also show difference in methylation variation in the brain in patients with schizophrenia.
