Originating in the work of Ernst Haeckel and Wilhelm Preyer, and advanced by a Prussian embryologist, Wilhelm Roux, the idea of struggle for existence between body parts helped to establish a framework, in which population cell dynamics rather than a predefined harmony guides adaptive changes in an organism. Intended to provide a causal-mechanical view of functional adjustments in body parts, this framework was also embraced later by early pioneers of immunology to address the question of vaccine effectiveness and pathogen resistance. (...) As an extension of these early efforts, Elie Metchnikoff established an evolutionary vision of immunity, development, pathology, and senescence, in which phagocyte-driven selection and struggle promote adaptive changes in an organism. Despite its promising start, the idea of somatic evolution lost its appeal at the turn of the twentieth century giving way to a vision, in which an organism operates as a genetically uniform, harmonious entity.

Nietzsche writes a preface to _The Gay Science_ in 1886, four years after its first four books were in print. In this address, he explains that he has _been ill_ and is _in recovery_. He diagnoses himself as having suffered from “romanticism.” Nietzsche warns that he will henceforth vent his malice on the sort of lyrical romantic sentimentalism from which he suffered. Nietzsche then undertakes to write an additional fifth book to the corpus, which he added in 1887—a year after (...) the above-referenced preface, thereby providing a _new_ end in departure from his previous romantic excursions of the initial four books of _GS_. I wish to trace how these claims—of illness and convalescence are related to what I argue is a major philosophical turn in Nietzsche’s thinking on the nature of reality and how reality matters to us—as value. In this essay, I will locate Nietzsche’s turn. To do so, I explain (1) what Nietzsche describes as “romantic pessimism,” that is, an epistemological dualism (i.e., assertion of an irresolvable appearance versus reality distinction). I will first explain and then show how Nietzsche suffers from this illness in the early books of _GS_, using textual examples to demonstrate his epistemological presuppositions and romantic-pessimistic preferences (which manifest as a defiant claim that fictions are preferred to reality, thereby still crediting an appearance-reality distinction); (2) how by his later book five of _GS_ Nietzsche plays a different tune by which prior dualisms dissolve in his affirmation of a co-implication of fiction and truth, such that (a) neither are wholly separate from the other, and (b) it becomes difficult if not impossible to distinguish between them.

This essay contrasts Nietzsche’s remarks on elite education with W.E.B. Du Bois’ demand for democratized education. The essay takes their remarks as springboards for a twenty-first century philosophy of education rather than an historical account of their philosophies. Both thinkers cultivated Kant and Hegel’s dream that the spirit of freedom guided by reason would unite all the world’s peoples. Both held that education was key to realizing the dream. Their judgments about qualifying for education separated them. Nietzsche insisted that only (...) the elite should receive the fullest measure of education. Du Bois believed that in the future virtually every human being would receive a university-level education. The essay’s principal point is to show how contemporary technology can make Du Bois’ dream a reality. An African philosopher’s working model demonstrates a path to universal university education.

This paper argues there are crucial points in Nietzsche’s texts where he offers a priori epistemic justification for views he believes are correct. My reading contrasts with the dominant view that Nietzsche’s philosophical naturalism is incompatible with a priori justification. My aim is to develop Nietzsche’s brand of a priori justification, show that he employs this account of justification in the texts, and suggest how it might be compatible with naturalism.

Amplifying Bernard Williams’ critique of the Nietzschean project of a revaluation of values, this paper mounts a critique of the idea that whether values will help us to live can serve as a criterion for choosing which values to live by. I explore why it might not serve as a criterion and highlight a number of further difficulties faced by the Nietzschean project. I then come to Nietzsche's defence, arguing that if we distinguish valuations from values, there is at least (...) one form of the project which overcomes those difficulties. Finally, however, I show that even on this reading, the project must either fall prey to ‘Saint-Just's illusion’ or fall back into the problems it was supposed to escape. This highlights important difficulties faced by the Nietzschean project and its descendants while also explaining why Williams, who was so Nietzschean in other respects, remained wary of the revaluation of values as a project.

Artificial intelligence is likely to undermine the anthropocentrism of humanism, the master narrative that undergirds the modern world. Humanity will need a new story to structure our beliefs and cooperation around. As different regions explore posthumanist alternatives through fiction, they bring with them distinct traditions of thought. The Swedish TV series _Real Humans_ (2012–2014) and its British remake, _Humans_ (2015–2018), dramatize the challenge of freeing oneself from cultural presumptions. When negotiating personhood with humanoid robots, the Swedish protagonist family presupposes a (...) social-democratic ethos, which is a trace of Scandinavian humanism that carries into the family’s posthumanist beliefs. Using Heideggerian and related perspectives, I analyze these series to make a case for a _dataist_ ontology with potential to re-enchant the modern world and bring forth a new epoch of being. Such a master narrative of _algorithmic universality_ could be facilitated by a new level of interconnectedness made possible by AI. This ontology fulfills the requirements of Robbins and Horta (Introduction, Cosmopolitanisms. New York University Press, New York, pp 1–17, 2017) who call for a cosmopolitanism of inclusivity with room for overlapping conceptions to remedy our present era’s international dysfunction. The Swedish and British TV series suggest that even if humanity’s uniting around a dataist master narrative were to be driven by intercultural competition, the decisive choice might be out of human hands. Paradoxically, such disempowering in terms of agency is portrayed as necessary for human _re-enchantment_. (shrink)
