What is it to make an error in the identification of a named taxonomic group? In this article we argue that the conditions for being in error about the identity of taxonomic groups through their names have a history, and that the possibility of committing such errors is contingent on the regime of institutions and conventions governing taxonomy and nomenclature at any given point in time. More specifically, we claim that taxonomists today can be in error about the identity (...) of taxonomic groups in a way that Carl Linnaeus, who is routinely cited as the “founder” of modern taxonomy and nomenclature, simply could not be. Starting from a remarkable recent study into Linnaeus’s naming of Elephasmaximus that led to the discovery of a nomenclatural error by him, we reconsider what it could mean to discover that Linnaeus misidentified a biological taxon in applying his taxon names. Through a further case study in Linnaean botany, we show that his practices of applying names in taxonomic revisions reveal a take on determining “which taxon is which” that is strikingly different from that of contemporary taxonomists. Linnaeus, we argue, adopted a practice-based, hands-on concept of taxa as “nominal spaces” that could continue to represent the same taxon even if all its former members had been reallocated to other taxa.

The vast majority of biological taxonomists use the Linnaean system when constructing classifications. Taxa are assigned Linnaean ranks and taxon names are devised according to the Linnaean rules of nomenclature. Unfortunately, the Linnaean system has become theoretically outdated. Moreover, its continued use causes a number of practical problems. This paper begins by sketching the ontological and practical problems facing the Linnaean system. Those problems are sufficiently pressing that alternative systems of classification should be investigated. (...) A number of proposals for an alternative system are introduced and evaluated. The best aspects of those proposals are brought together to form a post-Linnaean system, and a comparison of the Linnaean and post-Linnaean systems is conducted. The final section of this paper considers not only the theoretical reasons for replacing the Linnaean system, but also the practical feasibility of adopting an alternative system. (shrink)

Contrary to the traditional claim that needs for unambiguous communication about animal and plant species are best served by a single set of names ruled by international Codes, I suggest that a more diversified system is required, especially to cope with problems emerging from aggregation of biodiversity data in large databases. Departures from Linnaean nomenclature are sometimes intentional, but there are also other, less obvious but widespread forms of not Code-compliant grey nomenclature. A first problem is due to (...) the circumstance that the Codes are intended to rule over the way names are applied to species and other taxonomic units, whereas users of taxonomy need names to be applied to specimens. For different reasons, it is often impossible to refer a specimen with certainty to a named species, and in those cases an open nomenclature is employed. Second, molecular taxonomy leads to the discovery of clusters of gene sequence diversity not necessarily equivalent to the species recognized and named by taxonomists. Those clusters are mostly indicated with informal names or formulas that challenge comparison between different publications or databases. In several instances, it is not even clear if a formula refers to an individual voucher specimen, or is a provisional species name. The use of non-Linnaean names and formulas must be revised and strengthened by fixing standard formats for the different kinds of objects or hypotheses and providing permanent association of ‘grey names’ with standardized source information such as author and year. In the context of a broad-scope revisitation of aims and scope of scientific nomenclature, it may be worth rethinking if natural objects like plant galls and lichens, although other than the ‘single-entity’ objects traditionally covered by biological classifications, may nevertheless deserve taxonomic names.

Linnaean-style, rank-based codes of taxonomic nomenclature provide stability to the relation between taxon names and their referents through the device of nomenclatural types. The practice of using types to tether names to taxa is uncontroversial and well-understood. But the nature of the relation between types, names, and taxa continues to be a topic of philosophical debate. A particularly contested issue is whether it is necessary for taxa that have a type specimen to contain their type specimen. (...) Jerzy Brzozowski has recently offered a novel account of taxon names that, he claims, shows that the relation between a type specimen and the (sub)species it belongs to is contingent (Brzozowski in Hist Philos Life Sci 42(3):1–25, 2020). I argue that this is mistaken. While Brzozowski’s contribution helps to advance the debate by bringing concepts from the philosophy of reference to bear on taxonomic naming practices, his new account of taxon names fails to support his central argument. Indeed, I show that the philosophical concepts he introduces into the debate cement the view that it is necessary for a (sub)species with a type specimen to contain it. (shrink)

Biological type specimens are a particular kind of voucher specimen stored in natural history collections. Their special status and practical use are discussed in relation to the description and naming of taxonomic zoological diversity. Our current system, known as Linnaean nomenclature, is governed by the International Code of Zoological Nomenclature. The name of a species is fixed by its name-bearing type specimen, linking the scientific name of a species to the type specimen first designated for that species. The name-bearing (...) type specimen is not necessarily a typical example of the species, while establishment of the boundaries of a species requires empirical taxonomic studies. The International Code of Zoological Nomenclature allows for the naming of new species in the absence of preserved specimens. However, photos and DNA sequences should not function as primary type material, while new species should not be described and named without deposition of at least one type specimen in a collection. Philosophically, species are individuals, spatiotemporally restricted entities. Therefore, Linnaean species names are proper names, which do not define the taxon but serve as a label, providing an ostensive definition of a species. Paratypes have no name-bearing function but, nevertheless, are highly valued specimens in natural history collections. Paratypes should be restricted to those specimens originating from the same sample as the holotype. Diagnosis of a species taxon involves establishment of a connection between a Linnaean name and determination of the boundaries of the species. A first step in this process is the choice of an appropriate species concept. It is not the examination of holotypes and paratypes that necessarily provides the best estimate of the taxonomic boundaries of a species, but this is facilitated by a set of voucher specimens known as the hypodigm. Dissatisfaction with the present nomenclatural code led some researchers to propose emendations. Other taxonomists suggested abandoning Linnaean nomenclature and proposed the alternative PhyloCode, albeit that it relegates the naming of species taxa to the traditional nomenclatural codes.

Evolutionary and organismal biology have become inundated with data. At the same rate, we are experiencing a surge in broader evolutionary and ecological syntheses for which tree-thinking is the staple for a variety of post-tree analyses. To fully take advantage of this wealth of data to discover and understand large-scale evolutionary and ecological patterns, computational data integration, i.e., the use of machines to link data at large scale, is crucial. The most common shared entity by which evolutionary and ecological data (...) need to be linked is the taxon to which they belong. We propose a set of requirements that a system for defining such taxa should meet for computational data science: taxon definitions should maintain conceptual consistency, be reproducible via a known algorithm, be computationally automatable, and be applicable across the Tree of Life. We argue that Linnaean names, the most prevalent means of linking data to taxa, fail to meet these requirements due to fundamental theoretical and practical shortfalls. We argue that for the purposes of data-integration we should instead use phylogenetic definitions transformed into formal logic expressions. We call such expressions “phyloreferences”, and argue that, unlike Linnaean names, they meet all requirements for effective data-integration. (shrink)

This paper addresses early modern botanical nomenclature, the practices of identifying and publishing synonyms in particular, as a collaborative “information science”. Before Linnaean nomenclature became the lingua franca of botany, it was inevitable that, over time, the same plant was given several names by different people, which created confusion and made communication among botanists increasingly difficult. What names counted as synonyms and actually referred to the same plant had to be identified by meticulously comparing living and dried (...) specimens of this and similar plants as well as relevant illustrations und descriptions in the botanical literature. Identifying synonyms required and generated an ever-expanding mass of data, which was used continuously to adjust and rearrange plant names. Despite the greatest care, judgements on synonyms were not definitive, which meant that published lists of synonyms for individual species of plants were in a state of flux and had to be constantly updated, corrected, and rewritten. This required long-term international collaborations, the accumulated results of which were not published once but consecutively, in augmented and corrected editions of a book. As a result of this networked approach, synonyms are networked names that reflect the epistemic interconnectedness of the botanical community. These questions will be discussed with a focus on the Dutch botanist Johannes Burman, who placed synonyms at the centre of his work as posthumous editor—and co-author—of the botanical manuscripts that were left behind by other botanists.

Ethnobotanical research provides ample justification for comparing diverse biological nomenclatures and exploring ways that retain alternative naming practices. However, how (and whether) comparison of nomenclatures is possible remains a subject of discussion. The comparison of diverse nomenclatural practices introduces a suite of epistemic and ontological difficulties and considerations. Different nomenclatures may depend on whether the communities using them rely on formalized naming conventions; cultural or spiritual valuations; or worldviews. Because of this, some argue that the different naming practices may not (...) be comparable if the ontological commitments employed differ. Comparisons between different nomenclatures cannot assume that either the naming practices or the object to which these names are intended to apply identifies some universally agreed upon object of interest. Investigating this suite of philosophical problems, I explore the role grey nomenclatures play in classification. ‘Grey nomenclatures’ are defined as those that employ names that are either intentionally or accidentally non-Linnaean. The classification of the lichen thallus (a symbiont) has been classified outside the Linnaean system by botanists relying on the International Code of Nomenclature for algae, fungi, and plants (ICN). But, I argue, the use of grey names is not isolated and does not occur exclusively within institutionalized naming practices. I suggest, ‘grey names’ also aptly describe nomenclatures employed by indigenous communities such as the Samí of Northern Finmark, the Sherpa of Nepal, and the Okanagan First Nations. I pay particular attention to how naming practices are employed in these communities; what ontological commitments they hold; for what purposes are these names used; and what anchors the community’s nomenclatural practices. Exploring the history of lichen naming and early ethnolichenological research, I then investigate the stakes that must be considered for any attempt to preserve, retain, integrate, or compare the knowledge contained in both academically formalized grey names and indigenous nomenclatures in a way that preserves their source-specific informational content.

-/- Species lists play an important role in biology and practical domains like conservation, legislation, biosecurity and trade regulation. However, their effective use by non-specialist scientific and societal users is sometimes hindered by disagreements between competing lists. While it is well-known that such disagreements exist, it remains unclear how prevalent they are, what their nature is, and what causes them. In this study, we argue that these questions should be investigated using methods based on taxon concept rather than methods based (...) on Linnaean names, and use such a concept-based method to quantify disagreement about bird classification and investigate its relation to research effort. We found that there was disagreement about 38% of all groups of birds recognized as a species, more than three times as much as indicated by previous measures. Disagreement about the delimitation of bird groups was the most common kind of conflict, outnumbering disagreement about nomenclature and disagreement about rank. While high levels of conflict about rank were associated with lower levels of research effort, this was not the case for conflict about the delimitation of bird groups. This suggests that taxonomic disagreement cannot be resolved simply by increasing research effort. (shrink)

This study analyzes shells of marine gastropods of a zoological museum and the Latin epithets expressing perceptual and connotative attributes that they have received in the standard, Linnaean nomenclature. Making use of the Osgood semantic differential, we presented the subjects with digital 3-D reproductions of the shell specimens to be subjectively evaluated according to 17 pairs of attributes. The results show that, overall, the subjective evaluations given by the subjects are consistent, which suggests that an intersubjective characterization of the (...) shells as wholes according to their qualitative and morphological traits is possible and scientifically explicable. This may apply to other biological items as well. The results also show that the epithets given to the shells by taxonomists do not always reflect the perceptual evaluation of the general population, being a product of the well-known ambiguity in taxonomic categorization and naming.

The interpretation of man which I have defended in my book, Theory of Man, agrees with the Linnaean designation of homo sapiens, which is more exact, in my opinion, than the classical one of “rational animal.” In that work I maintain that what is peculiar to man is that he is conscious of a reality outside of himself and of his own intimate being, or, in other words, that he recognizes the independent existence of the world and is an (...) ego. Both matters can be reduced to a unique primary function: the objectifying activity, which in normal, continuous, and accumulative operation belongs only to man, and from which all essentially human traits are derived. The peculiar characteristic of perception properly so called, that is, human perception, is the observation of things that are present, the recognition that a given thing exists. To perceive, then, is to attribute presence or existence to what is perceived, to admit it as an object existing by itself, certainly in different ways according to whether it is a question of external things, of the subjective entity, or of the processes and “states” inherent in it; let it be noted that when perceptive attention fastens upon the “states,” that is to say, on subjective, unintentional processes like those of coenesthesia which ordinarily are not perceived but are lived, enjoyed, or suffered, these become objectified without losing in themselves their condition of states. The capacity to objectify is the bedrock of human nature; animal conscience (if it deserves this name) must be imagined, save for rare exceptions, to be a succession of “states” to which objectifying attention is not applied because such attention can only come from an ego.

The orthodox view of proper names, Millianism, provides a very simple and elegant explanation of the semantic contribution of referential uses of names–names that occur as bare singulars and as the argument of a predicate. However, one problem for Millianism is that it cannot explain the semantic contribution of predicative uses of names. In recent years, an alternative view, so-called the-predicativism, has become increasingly popular. According to the-predicativists, names are uniformly count nouns. This straightforwardly explains (...) why names can be used predicatively, but is prima facie less congenial to an analysis of referential uses. To address this issue, the-predicativists argue that referential names are in fact complex determiner phrases consisting of a covert definite determiner and a count noun—and so, a referential name is a definite description. In this paper, I will argue that despite the appearance of increased theoretical complexity, the view that names are ambiguous between predicative and referential types is in fact superior to the unitary the-predicativist view. However, I will also argue that to see why this ambiguity view is better, we need to give up the standard Millian analysis. Consequently, I will first propose an alternative analysis of referential names that retains the virtues of Millianism, but provides an important explanatory connection to the predicative uses. Once this analysis of names is adopted, the explanation for why names are systematically ambiguous between referential and predicative types is both simple and elegant. Second, I will argue that the-predicativism has the appearance of being simpler than an ambiguity view, but is in fact unable to account for certain key properties of referential names without making ad hoc stipulations.

This paper is a counter to the view that names are always predicates with the same extension as a metalinguistic predicate with the form “is a thing called “N”” (the Predicate View). The Predicate View is in opposition to the Referential View of names. In this paper, I undermine one argument for the Predicate View. The Predicate View’s adherents take examples of uses of names that have the surface appearance of a predicate and generalise from these to (...) treat uses of names that do not have the surface appearance of a predicate. They show that the Predicate View can provide a unified account of these two uses and assume that the Referential account cannot. I propose an alternative view of names, the Polysemy View. This view allows one to resist the pressure to generalise from the cases with the surface appearance of predicates to all uses of names while nevertheless providing connections between the uses. On the Polysemy View names are not, in their core use, metalinguistic predicates. Names are predominantly referring expressions but they also freelance as metalinguistic predicates on occasion. They have a double life. This double life is possible because of the pragmatic and conventional connections between the two aspects of that life. My main aim in this paper is to show that the Predicate View is not the only view that can give a good account of apparently predicative uses of names. In addition, I offer some inconclusive reasons to prefer the Polysemy View over the Predicate View. My paper assumes a background framework that the Predicate and Referentialist Views share and I do not attempt to justify that framework. I ignore many other views of names (notably descriptivist views and relevance theoretic views) in order to focus on the debate between these two opponents. (shrink)

The standard versions of predicativism are committed to the following two theses: proper names are count nouns in all their occurrences, and names do not refer to objects but express name-bearing properties. The main motivation for predicativism is to provide a uniform explanation of referential names and predicative names. According to predicativism, predicative names are fundamental and referential names are explained by appealing to a null determiner functioning like “the” or “that.” This paper has (...) two goals. The first is to reject the predicativists’ explanation of the two types of names. I present three syntactic counterexamples to the predicativists’ account of referential names: incorporation, modification, and measure phrase uses. The second goal is to present a novel strategy to explain the two types of names. I propose that referential names are fundamental but that there are null morphemes available for transforming a name into a count noun (and possibly into other syntactic categories). (shrink)

The result of combining classical quantificational logic with modal logic proves necessitism – the claim that necessarily everything is necessarily identical to something. This problem is reflected in the purely quantificational theory by theorems such as ∃x t=x; it is a theorem, for example, that something is identical to Timothy Williamson. The standard way to avoid these consequences is to weaken the theory of quantification to a certain kind of free logic. However, it has often been noted that in order (...) to specify the truth conditions of certain sentences involving constants or variables that don’t denote, one has to apparently quantify over things that are not identical to anything. In this paper I defend a contingentist, non-Meinongian metaphysics within a positive free logic. I argue that although certain names and free variables do not actually refer to anything, in each case there might have been something they actually refer to, allowing one to interpret the contingentist claims without quantifying over mere possibilia.

An original and provocative book that illuminates the origins of philosophy in ancient Greece by revealing the surprising early meanings of the word "philosopher" Calling Philosophers Names provides a groundbreaking account of the origins of the term philosophos or "philosopher" in ancient Greece. Tracing the evolution of the word's meaning over its first two centuries, Christopher Moore shows how it first referred to aspiring political sages and advice-givers, then to avid conversationalists about virtue, and finally to investigators who focused (...) on the scope and conditions of those conversations. Questioning the familiar view that philosophers from the beginning "loved wisdom" or merely "cultivated their intellect," Moore shows that they were instead mocked as laughably unrealistic for thinking that their incessant talking and study would earn them social status or political and moral authority. Taking a new approach to the history of early Greek philosophy, Calling Philosophers Names seeks to understand who were called philosophoi or "philosophers" and why, and how the use of and reflections on the word contributed to the rise of a discipline. Drawing on a wide range of evidence, the book demonstrates that a word that began in part as a wry reference to a far-flung political bloc came, hardly a century later, to mean a life of determined self-improvement based on research, reflection, and deliberation. Early philosophy dedicated itself to justifying its own dubious-seeming enterprise. And this original impulse to seek legitimacy holds novel implications for understanding the history of the discipline and its influence. (shrink)

There is a tension within Ockham's theory of mental language between its claim to being a semantics for conventional languages and its claim to being a model of concept acquisition and thought. In particular, the commitment to a redundancy-free mental language which serves to explain important semantic relations such as synonymy and ambiguity conflicts, _prima facie, with the possibility of opaque belief contexts. I argue that it is preferable to treat the theory of mental language as an idealized theory of (...) cognitive competence than to forfeit, as Jerry Fodor does, the commitment to conceptual parsimony.

In this essay I will defend a novel version of the indexical view on proper names. According to this version, proper names have a relatively sparse truth-conditional meaning that is represented by their rigid content and indexical character, but a relatively rich use-conditional meaning, which I call the (contextual) constraint of a proper name. Firstly, I will provide a brief outline of my favoured indexical view on names in contrast to other indexical views proposed in the relevant (...) literature. Secondly, two general motivations for an indexical view on names will be introduced and defended. Thirdly, I will criticize the two most popular versions of the indexical view on names: formal variable accounts and salience-based formal constant accounts. In the fourth and final section, I will develop my own use-conditional indexical view on names in three different steps by confronting an initial version of this view with three different challenges.

We investigate an enrichment of the propositional modal language L with a "universal" modality ■ having semantics x ⊧ ■φ iff ∀y(y ⊧ φ), and a countable set of "names" - a special kind of propositional variables ranging over singleton sets of worlds. The obtained language ℒ $_{c}$ proves to have a great expressive power. It is equivalent with respect to modal definability to another enrichment ℒ(⍯) of ℒ, where ⍯ is an additional modality with the semantics x ⊧ (...) ⍯φ iff Vy(y ≠ x → y ⊧ φ). Model-theoretic characterizations of modal definability in these languages are obtained. Further we consider deductive systems in ℒ $_{c}$ . Strong completeness of the normal ℒ $_{c}$ logics is proved with respect to models in which all worlds are named. Every ℒ $_{c}$ -logic axiomatized by formulae containing only names (but not propositional variables) is proved to be strongly frame-complete. Problems concerning transfer of properties ([in]completeness, filtration, finite model property etc.) from ℒ to ℒ $_{c}$ are discussed. Finally, further perspectives for names in multimodal environment are briefly sketched. (shrink)

Combining elements from Heidegger’s philosophy of “being-in-the-world” and the tradition of Jewish theology, Levinas has evolved a new type of ethics based on a concept of “the Other” in two different but complementary aspects. He describes his encounters with those philosophers and literary authors (most of them his contemporaries) whose writings have most significantly contributed to the construction of his own philosophy of “Otherness”: Agnon, Buber, Celan, Delhomme, Derrida, Jabès, Kierkegaard, Lacroix, Laporte, Picard, Proust, Van Breda, Wahl, and, most notably, (...) Blanchot. At the same time, Levinas’s own texts are inscriptions and documents of those encounters with “Others” around which his philosophy is turning. Thus the texts simultaneously convey an immediate experience of how his intellectual position emerged and how it is put into practice. A third potential function of the book is that it unfolds the network of references and persons in philosophical debates since Kierkegaard. (shrink)

In the contemporary debate about the nature of persistence, stage theory is the view that ordinary objects (artefacts, animals, persons, etc.) are instantaneous and persist by being suitably related to other instantaneous objects. In this paper I focus on the issue of what stage theorists should say about the semantics of ordinary proper names, like ‘Socrates’ or ‘London’. I consider the remarks that stage theorists actually make about this issue, present some problems they face, and finally offer what I (...) take to be the best alternative available for them.

It has been persuasively argued by David Kaplan and others that the proposition expressed by statements like (1) is a singular proposition, true in just those worlds in which a certain person, David Israel, is a computer scientist. Call this proposition P . The truth of this proposition does not require that the utterance (1) occur, or even that Israel has ever said anything at all. Marcus, Donnellan, Kripke and others have persuasively argued for a view of proper names (...) that, put in Kaplan’s terms and applied to this example, implies that the proposition expressed by (2) is also simply P .1 The thesis that expressions of a certain category (names, indexicals, demonstratives, pronouns, descriptions, etc.) are referential 2holds that these expressions contribute the object to which they refer, rather than a mode of presentation of that object, to the propositions expressed by statements containing them.

In this paper we defend a direct reference theory of names. We maintain that the meaning of a name is its bearer. In the case of vacuous names, there is no bearer and they have no meaning. We develop a unified theory of names such that one theory applies to names whether they occur within or outside fiction. Hence, we apply our theory to sentences containing names within fiction, sentences about fiction or sentences making comparisons (...) across fictions. We then defend our theory against objections and compare our view to the views of Currie, Walton, and others. (shrink)
