Prompted by the thesis that an organism’s umwelt possesses not just a descriptive dimension, but a normative one as well, some have sought to annex semiotics with ethics. Yet the pronouncements made in this vein have consisted mainly in rehearsing accepted moral intuitions, and have failed to concretely further our knowledge of why or how a creature comes to order objects in its environment in accordance with axiological charges of value or disvalue. For want of a more explicit account, theorists (...) writing on the topic have relied almost exclusively on semiotic insights about perception originally designed as part of a sophisticated refutation of idealism. The end result, which has been a form of direct givenness, has thus been far from convincing. In an effort to bring substance to the right-headed suggestion that values are rooted in the biological and conform to species-specific requirements, we present a novel conception that strives to make explicit the elemental structure underlying umwelt normativity. Building and expanding on the seminal work of Ayn Rand in metaethics, we describe values as an intertwined lattice which takes a creature’s own embodied life as its ultimate standard; and endeavour to show how, from this, all subsequent valuations can in principle be determined.

The doctrine of the arbitrary assertion is a key part of Objectivist epistemology as elaborated by Leonard Peikoff. For Peikoff, assertions unsupported by evidence are neither true nor false; they have no context or place in the hierarchy of conceptual knowledge; they are meaningless and paralyze rational cognition; their production is proof of irrationality. A thorough examination of the doctrine reveals worrisomely unclear standards of evidence and a jumble of contradictory claims about which assertions are arbitrary, when they are arbitrary, (...) and what ought to be done about them when they are. A wholesale rejection of the doctrine is recommended. (shrink)

It is often claimed that one of Darwin''s chief accomplishments was to provide biology with a non-teleological explanation of adaptation. A number of Darwin''s closest associates, however, and Darwin himself, did not see it that way. In order to assess whether Darwin''s version of evolutionary theory does or does not employ teleological explanation, two of his botanical studies are examined. The result of this examination is that Darwin sees selection explanations of adaptations as teleological explanations. The confusion in the nineteenth (...) century about Darwin''s attitude to teleology is argued to be a result of Darwin''s teleological explanations not conforming to either of the dominant philosophical justifications of teleology at that time. Darwin''s explanatory practices conform well, however, to recent defenses of the teleological character of selection explanations. (shrink)

With the advent of social networking websites, privacy concerns have reached a new high. One particularly problematic concern entails employers requesting login credentials to popular social media platforms. While many people may consider this request unethical, they may not agree on the reasons it is unethical. One reason may be to blame the behavior on egoism. Egoism, however, comes in multiple flavors, not all of which would agree that violating privacy is acceptable. In this paper, we articulate how one egoist (...) perspective provides a defense of privacy in the face of unjust information access requests. Objectivism, the philosophy of Ayn Rand, offers an egoist approach to ethics that values individual privacy on rational, self-interested grounds. By applying Objectivist principles to a business context, we observe that businesspeople should not violate other people’s privacy for short-term gains. Furthermore, we observe that privacy can be protected without distinct right to privacy. Rather, Objectivism’s conception of rational self-interest suggests that long-term flourishing is the proper end of individuals and businesses, predicated on, among other things, respecting privacy and enforcing individual rights.

Darwinism designates a distinctive form of evolutionary explanation for the history and diversity of life on earth. Its original formulation is provided in the first edition of On the Origin of Species in 1859. This entry first formulates ‘Darwin's Darwinism’ in terms of five philosophically distinctive themes: (i) probability and chance, (ii) the nature, power and scope of selection, (iii) adaptation and teleology, (iv) nominalism vs. essentialism about species and (v) the tempo and mode of evolutionary change. Both Darwin and (...) his critics recognized that his approach to evolution was distinctive on each of these topics, and it remains true that, though Darwinism has developed in many ways unforeseen by Darwin, its proponents and critics continue to differentiate it from other approaches in evolutionary biology by focusing on these themes. This point is illustrated in the second half of the entry by looking at current debates in the philosophy of evolutionary biology on these five themes, with a special focus on Stephen Jay Gould's The Structure of Evolutionary Theory.

This research offers a new perspective by reframing the positivist-interpretive debate as a distinction between the functional outcomes of research: explanation and understanding. Based on an older and well-established literature in philosophy, this distinction can reinvigorate important differences in research outcomes that have been lost. Understanding or “subjective meaning” is connected to the intentionality, thoughts, and motivations of the human subjects under study. From this perspective, understanding is the type of knowledge gained from determining the meanings, categories, and symbols humans (...) attach to actions, knowledge, and systems. In contrast, explanation is achieved by subsuming individual instantiations of the phenomenon under broad general laws, or identifying causal mechanisms that support antecedent-consequent pairs. Researchers can proactively use the understanding-explanation distinction as a heuristic to create new lines of research questions based on what has not been explained or understood rather than on which ontology or methodology has not been used.

Until recently it has been conventional to assume that ethical egoism is "ethical" is name, alone, and that no account that considers one's own interests as the standard of moral obligation could count as seriously "ethical." In recent years, however, philosophers have shown increasing respect for more sophisticated forms of ethical egoism which attempt to define self-interest in enriched terms characterizing self-interest as human flourishing in both material and psychological dimensions. But philosophers are still skeptical that any conception of self-interest (...) could underpin ethical theory. This paper considers recent arguments by Richard Joyce, who is willing to concede enriched conceptions of self-interest, but who claims that egoism cannot support appropriate counterfactual conditionals about morality, or inferential uses of ordinary moral thinking. I argue that ethical egoism can satisfy each of Joyce's desiderata for morality, provided that it is taken to involve the very notion of enriched self-interest that Joyce is elsewhere willing to consider. In showing that egoism can count as a moral theory, I show, in effect, that Joyce's arguments for error theory about morality are really arguments for error theory about agent-neutral, non-egoistic morality.

“Naturalized epistemology” is a recent attempt to transform the theory of knowledge into a branch of natural science. Traditional epistemologists object to this proposal on the grounds that it eliminates the distinctively philosophical content of epistemology. In this thesis, I argue that traditional philosophers are justified in their reluctance to accept naturalism, but that their ongoing inability to refute it points to deeper problems inherent in traditional epistemology. I establish my thesis first by critiquing three versions of naturalism, showing that (...) each version either fails to implement its objectives consistently or starts from dubious objectives. “Optimistic naturalism” attempts to use naturalistic methods to give positive answers to traditional epistemological questions (such as by affirming that our beliefs can be justified). This fails because the form of traditional questions requires the concept “belief,” a concept that I argue naturalistic methodology cannot countenance (because of the severe constraints of naturalistic semantic theory). “Pessimistic naturalism,” the version advocated by Quine, is more consistent with naturalistic methodology, but fails because hidden behind its conclusions are assumptions (such as the underdetermination thesis) that cannot themselves be naturalized in the full context of scientific evidence. A final attempt to naturalize epistemology, deflationary naturalism, dispenses with traditional questions entirely, urging that the terms “knowledge” and “justification” be taken as mere pragmatic devices whose use can, nevertheless, be studied scientifically. Curiously, this view fails to take account of important facts about the actual use of those terms, as studied by psychologists. In the end, despite problems with each of these versions, traditional philosophers can learn something from their encounter with naturalism. In the course of showing how various naturalistic doctrines cannot themselves be naturalized, I identify the flaws in traditional epistemology (such as its reliance on a priorism, and its resulting inability to articulate a workable empirical foundationalist theory of justification) that make naturalism harder to challenge. These flaws must be corrected if philosophers are to preserve the autonomy of their discipline. (shrink)
