Perfect being theism is the view that the perfect being exists and the property being-perfect is the property being-God. According to the strong analysis of perfection, a being is perfect just in case it exemplifies all perfections. On the other hand, the weak analysis of perfection claims that a being is perfect just in case it exemplifies the best possible combination of compatible perfections. Strong perfect being theism accepts the former analysis while weak perfect being theism accepts the latter. In (...) this paper, I argue that there are good reasons to reject both versions of perfect being theism. On the one hand, strong perfect being theism is false if there are incompatible perfections; I argue that there are. On the other hand, if either no comparison can be made between sets of perfections, or they are equally good, then there is no best possible set of perfections. I argue for the antecedent of this conditional statement, concluding that weak perfect being theism is false. In the absence of other analyses of perfection, I conclude that we have reason to reject perfect being theism. (shrink)

In this paper, I defend McKinsey's argument (Analysis 1991) that Burge's antiindividualist position is incompatible with privileged access, viz. the claim that each subject can know his own thought contents just by reflection and without having undertaken an empirical investigation. I argue that Burge thinks that there are certain necessary conditions for a subject to have thoughts involving certain sorts of concepts; these conditions are appropriately different for thoughts involving natural kind concepts and thoughts involving non-natural kind concepts. I use (...) Burge's commitment to these entailments to show that his antiindividualist position is incompatible with privileged access. (shrink)

In this paper I shall define a thesis I shall call ' determinism ', and argue that it is incompatible with the thesis that we are able to act otherwise than we do. Other theses, some of them very different from what I shall call ' determinism ', have at least an equal right to this name, and, therefore, I do not claim to show that every thesis that could be called ' determinism ' without historical impropriety is incompatible with (...) free will. I shall, however, assume without argument that what I call ' determinism ' is legitimately so called. In Part I, I shall explain what I mean by ' determinism '. In Part II, I shall make some remarks about 'can'. In Part III, I shall argue that free will and determinism are incompatible. In Part IV, I shall examine some possible objections to the argument of Part III. I shall not attempt to establish the truth or falsity of determinism, or the existence or nonexistence of free will.

Journal of Mathematical Logic, Volume 22, Issue 02, August 2022. We introduce bounded category forcing axioms for well-behaved classes [math]. These are strong forms of bounded forcing axioms which completely decide the theory of some initial segment of the universe [math] modulo forcing in [math], for some cardinal [math] naturally associated to [math]. These axioms naturally extend projective absoluteness for arbitrary set-forcing — in this situation [math] — to classes [math] with [math]. Unlike projective absoluteness, these higher bounded category forcing (...) axioms do not follow from large cardinal axioms but can be forced under mild large cardinal assumptions on [math]. We also show the existence of many classes [math] with [math] giving rise to pairwise incompatible theories for [math]. (shrink)

During the second half of the nineteenth century, electronegativity has been one of the most relevant chemical concepts to explain the relationships between chemical substances and their possible reactions. Specifically, EN is a property of the substances that allows them to attract external electrons in bonding situations. The problem arises because EN cannot be measured directly. Indeed, the only way to measure it is through different properties that do can be directly measured, for instance enthalpy, ionization energies or electron affinities. (...) What is particularly troubling about this case in quantum chemistry is that the different models used to describe and quantify EN are incompatible but, in a certain sense, equivalent because the same EN scale results in all of them. By analyzing Linus Pauling’s and Robert Mulliken’s models of EN, it will be argued that, if we remain cling to a traditional representative conception of models, we cannot understand the meaning of the information provided by those models. Indeed, if we do not want to adopt an instrumentalist point of view concerning chemical knowledge, we should reconsider by virtue of what a model represents the system, or, in other words, which the factors that determine the representative power of a model are. I will propose a new perspective that incorporates the role of experimental techniques in the very notion of representation; this perspective allows us to understand how supposedly incompatible models of the same target system can be both simultaneously representative.

Some have it that wholes are, somehow, identical to their parts. This doctrine is as alluring as it is puzzling. But in this paper, I show that the doctrine is inconsistent with two widely accepted theses. Something has to go.

The paper examines a single, apparently simple argument for the existence of incompatibilities between the virtues as traits of character. This argument appeals not to empirical truths about human psychology or human nature but to the possibility of conflict between the exercise of different virtues in action. There are, for example, situations in which we can exercise the virtue of truthfulness only at the expense of not exercising the virtue of tact, as when we are asked a question to which (...) the straightforward answer will pain our questioner. The person who in these situations would give a straightforward answer possesses the virtue of truthfulness to a higher degree than the person who would respond more evasively, whereas the latter person possesses the virtue of tact to a higher degree than the former. But since the two responses are mutually exclusive, it follows that the degree to which we possess the virtue of truthfulness must, at least in some measure, correlate inversely with the degree to which we possess the virtue of tact. And similarly for many other pairs of virtues. My paper focusses on the two cardinal assumptions of this argument, viz., (i) that sometimes the exercise of one virtue can conflict with the exercise of another, and (ii) that the degree to which a person possesses a virtue correlates directly with the extent of its exercise, and defends both assumptions against a variety of objections which allege that, in different ways, they are insensitive to the complexity of the virtues.

Religious pluralism is the view that more than one religion is correct, and that no religion enjoys a special status in relation to the ultimate. Yet the world religions appear to be incompatible. How, then, can more than one be correct? Discussions and critiques of religious pluralism usually focus on the work of John Hick, yet there are a number of other pluralists whose responses to this incompatibility problem are importantly different from Hick’s. This article surveys the solutions of (...) Hick, Harrison, Heim, Byrne, and Knitter to the incompatibility problem. I conclude that, while none of these views is without weakness, there are several promising pluralist solutions to this problem. Moreover, confessionalists (i.e. exclusivists and inclusivists) must also address issues related to incompatibility. (shrink)

This paper introduces a new framework, based on the notion of compatibility space, obtained by adding a primitive incompatibility relation to a state space in the sense of Fine. The key idea inspiring the framework is to modify Fine's truthmaker semantics by taking the notion of incompatibility as primitive, and use it to define other notions. We discuss some interesting features of the framework and explore its advantages over the standard framework of state spaces. We review some applications (...) of the framework, including proofs of soundness and completeness theorems for a number of logics, one way to use compatibility states to mirror Kripke frames, and an exploration of a way to use the new framework to provide truthmaking clauses for modal formulas.

This paper argues that the wants or desires of a person can be consistent with each other and still necessarily incompatible with each other and for interesting reasons. It is argued here that this problem is not rare and that there is no solution in sight.

The Consequence Argument is a staple in the defense of libertarianism, the view that free will is incompatible with determinism and that humans have free will. It is often thought that libertarianism is consistent with a certain naturalistic view of the world — that is, that libertarian free will can be had without metaphysical commitments beyond those pro- vided by our best (indeterministic) physics. In this paper, I argue that libertarians who endorse the Consequence Argument are forced to reject this (...) naturalistic worldview, since the Consequence Argument has a sis- ter argument — I call it the Supervenience Argument — which cannot be rejected without threatening either the Consequence Argument or the naturalistic worldview in question.

Are the following propositions true of the colors: No object can be more than one determinable or determinate color all over at the same time (Incompatibility); the colors of objects are mind-independent (Objectivism); and most human observers usually perceive the colors of objects veridically in typical conditions (Veridicality)? One reason to think not is that the empirical literature appears to support the proposition that there is mass perceptual disagreement about the colors of objects amongst human observers in typical conditions (...) (P-Disagreement). In this article, we defend Incompatibility, Objectivism, and Veridicality by calling into question whether the empirical literature really supports P-Disagreement. (shrink)

Two powerful arguments have famously dominated the realism debate in philosophy of science: The No Miracles Argument (NMA) and the Pessimistic Meta-Induction (PMI). A standard response to the PMI is selective scientific realism (SSR), wherein only the working posits of a theory are considered worthy of doxastic commitment. Building on the recent debate over the NMA and the connections between the NMA and the PMI, I here consider a stronger inductive argument that poses a direct challenge for SSR: Because it (...) is sometimes exactly the working posits which contradict each other, i.e., that which is directly responsible for empirical success, SSR cannot deliver a general explanation of scientific success.

This paper argues that two fundamentally incompatible shifts are taking place in higher education institutions in the UK, and beyond: Firstly, there is a move towards appreciation of, and focus on, interdisciplinary teaching, learning and research. Secondly, the university institution is undergoing neoliberal reforms, in the spirit of New Public Management. It is argued that the latter leads to an intensification of pressures to specialise into increasingly narrow disciplinary niches, which in terms is detrimental to the possibilities for interdisciplinary cooperation. (...) introduction of a feminist ethics of care into the university, as suggested by the feminist slow scholarship movement, is proposed as a possible solution to what is perceived to be negative developments in the higher education sector.

Ten arguments for the nonexistence of God are formulated and discussed briefly. Each of them ascribes to God a pair of properties from the following list of divine attributes: (a) perfect, (b) immutable, (c) transcendent, (d) nonphysical, (e) omniscient, (f) omnipresent, (g) personal, (h) free, (i) all-loving, (j) all-just, (k) all-merciful, and (1) the creator of the universe. Each argument aims to demonstrate an incompatibility between the two properties ascribed. The pairs considered are: 1. (a-1), 2. (b-1), 3. (b-e), (...) 4. (b-i), 5, (c-f), 6. (c-g), 7. (d-g), 8. (f-g), 9. (e-h), and 10. (j-k). Along the way, several other possible pairs are also mentioned and commented upon. (shrink)

The thesis of the empirical underdetermination of theories (U-thesis) maintains that there are incompatible theories which are empirically equivalent. Whether this is an interesting thesis depends on how the term incompatible is understood. In this paper a structural explication is proposed. More precisely, the U-thesis is studied in the framework of the model theoretic or emantic approach according to which theories are not to be taken as linguistic entities, but rather as families of mathematical structures. Theories of similarity structures are (...) studied as a paradigmatic case. The structural approach further reveals that the U-thesis is related to problems of uniqueness in the representational theory of measurement, questions of geometric conventionalism, and problems of structural underdetermination in mathematics.

In this paper, I discuss the analysis of logic in the pragmatic approach recently proposed by Brandom. I consider different consequence relations, formalized by classical, intuitionistic and linear logic, and I will argue that the formal theory developed by Brandom, even if provides powerful foundational insights on the relationship between logic and discursive practices, cannot account for important reasoning patterns represented by non-monotonic or resource-sensitive inferences. Then, I will present an incompatibility semantics in the framework of linear logic which (...) allow to refine Brandom’s concept of defeasible inference and to account for those non-monotonic and relevant inferences that are expressible in linear logic. Moreover, I will suggest an interpretation of discursive practices based on an abstract notion of agreement on what counts as a reason which is deeply connected with linear logic semantics. (shrink)

The central case for animalism is the ‘thinking animal problem’: if I am not an animal, this leads to an absurd multiplication of thinkers. One objection to this argument is that animalism faces a structurally analogous problem called the ‘thinking parts problem’: animalism ends up with an absurdity that any part of an animal that includes a brain can be a candidate for being a thinker. Some leading animalists try to avoid the thinking parts problem by eliminating the brain (and (...) other alleged thinking parts) from the animalist’s ontology. There are two versions of eliminativism that animalists endorse: biological eliminativism and causal eliminativism. I argue that these theories are incompatible with animalism and so do not solve the thinking parts problem. (shrink)

This paper deals with atheism, Sartre's notion of absolute freedom and Jean-Paul Sartre's claim of the irreconcilability of human freedom with God’s existence. For Sartre, man to be truly human must continuously create his own essence and continuously assert himself. Man can achieve this because he is absolutely free; the affirmation of God would undermine the exigencies of man's freedom and creativity. The question on the impossibility of the coexistence between the affirmation of God's existence and the recognition of human (...) freedom raises certain points against Sartre's notion of God and human freedom. The paper urges the believer to fully understand his beliefs and be also critical of his faith. (shrink)

It is commonly held that Wittgenstein abandoned the Tractatus largely because of a problem concerning color incompatibility. My aim is to solve this problem on Wittgenstein’s behalf. First I introduce the central program of the Tractatus (§1) and the color incompatibility problem (§2). Then I solve the problem without abandoning any Tractarian ideas (§3), and show that given certain weak assumptions, the central program of the Tractatus can in fact be accomplished (§4). I conclude by distinguishing my system (...) of analysis from others and by explaining the historical underpinnings of my understanding of the nature of elementary propositions (§5). (shrink)

Classical cognitive science assumes that intelligently behaving systems must be symbol processors that are implemented in physical systems such as brains or digital computers. By contrast, connectionists suppose that symbol manipulating systems could be approximations of neural networks dynamics. Both classicists and connectionists argue that symbolic computation and subsymbolic dynamics are incompatible, though on different grounds. While classicists say that connectionist architectures and symbol processors are either incompatible or the former are mere implementations of the latter, connectionists reply that neural (...) networks might be incompatible with symbol processors because the latter cannot be implementations of the former. In this contribution, the notions of 'incompatibility' and 'implementation' will be criticized to show that they must be revised in the context of the dynamical system approach to cognitive science. Examples for implementations of symbol processors that are incompatible with respect to contextual topologies will be discussed. (shrink)

Four studies explored people's judgments about whether particular types of behavior are compatible with determinism. Participants read a passage describing a deterministic universe, in which everything that happens is fully caused by whatever happened before it. They then assessed the degree to which different behaviors were possible in such a universe. Other participants evaluated the extent to which each of these behaviors had various features. We assessed the extent to which these features predicted judgments about whether the behaviors were possible (...) in a deterministic universe. Experiments 1 and 2 found that people's judgments about whether a behavior was compatible with determinism were not predicted by their judgments about whether that behavior relies on physical processes in the brain and body, is uniquely human, is unpredictable, or involves reasoning. Experiment 3, however, found that a distinction between what we call “active” and “passive” behaviors can explain people's judgments. Experiment 4 extended these findings, showing that we can measure this distinction in several ways and that it is robustly predicted by two different cues. Taken together, these results suggest that people carve up mentally guided behavior into two distinct types—understanding one type to be compatible with determinism, but another type to be fundamentally incompatible with determinism.

In fungi, cell fusion between genetically unlike individuals triggers a cell death reaction known as the incompatibility reaction. In Podospora anserina, the genes controlling this process belong to a gene family encoding STAND proteins with an N‐terminal cell death effector domain, a central NACHT domain and a C‐terminal WD‐repeat domain. These incompatibility genes are extremely polymorphic, subject to positive Darwinian selection and display a remarkable genetic plasticity allowing for constant diversification of the WD‐repeat domain responsible for recognition of (...) non‐self. Remarkably, the architecture of these proteins is related to pathogen‐recognition receptors ensuring innate immunity in plants and animals. Here, we hypothesize that these P. anserina incompatibility genes could be components of a yet‐unidentified innate immune system of fungi. As already proposed in the case of plant hybrid necrosis or graft rejection in mammals, incompatibility could be a by‐product of pathogen‐driven divergence in host defense genes. (shrink)

The completeness of quantum mechanics is generally interpreted to be or entail the following conditional statement ): If a QM system S is in a pure non-eigenstate of observable A, then S does not have value ak of A at t. QM itself can be assumed to contain two elements: a formula generating probabilities; Hamiltonians that can be time-dependent due to a time-dependent external potential. It is shown that, given and, QM and SC are incompatible. Hence, SC is not the (...) appropriate interpretation of the completeness of QM. (shrink)

ABSTRACTIsaiah Berlin’s idea of value pluralism has been extensively discussed in recent decades. However, there is still much controversy about the actual meaning and implication of the terms “incompatibility” and “incommensurability” when applied to values. This article analyses the Berlinian concept of value pluralism from a theoretical point of view and argues that, following Berlin’s work, incompatibility should be defined as the impossibility of two ends being combined at a maximum level―though it is possible to find compromises between (...) them when not pursued to their maximum―whereas incommensurability refers to the existence of more than one valid, rational solution to a conflict of ends. After commenting on the arguments advanced by other scholars, the presence of a certain idea of rationality in Berlin’s notion of value pluralism is advanced. Finally, it is demonstrated that incompatibility and incommensurability provide Berlin’s pluralism with its characteristic tragic feature which differentiates it from monism. (shrink)

The purpose of the study is to identify a common theoretical basis for the study of human life as capital and unconditional higher value. Theoretical basis is based on the value-laden and revised structural constructivism, provided by the French philosopher and sociologist Pierre Bourdieu, critical analysis of the concepts of capital as the embodiment of social expectations, the biological concept of the value of human life, as well as the concepts of its sanctity. Originality. It is proved that one should (...) not consider the value of human life as capital only but instead takes into account its different value interpretations, especially when forming the social identity of a person. Moreover, in each of the value systems, the value of human life can be recognized as unconditional, which does not prevent the coexistence of such different value interpretations within the framework of one social identity, which then inevitably becomes a multiple social identity. Conclusions. Human life cannot be considered as a result of integrating economic expectations into the concept of "advertising" capital: first, expectations may well be inadequate; second, expectations by themselves are not directly related to capital; third, expectations do not necessarily lead to development; fourth, one should clearly distinguish between the spontaneous "expectations" and the values that express people’s strong motivation as members of social communities. The multiplicity of possible cultural conditions that affirm the unconditional value of life indicates that this unconditionality is always relevant rather than absolute. The multiple social identities could be used to add value to the protection of human life, the affirmation of multiple social identities is a means of affirming the unconditional value of human life – it is unconditional in several alternative ways.

Is it consistent to maintain that human free will is incompatible with determinism in the natural world while also maintaining that it is compatible with divine universal causation? On the face of it, divine universal causation looks like a form of determinism. And the intuitions which lead to incompatibilism about free will and natural determinism also lead to incompatibilism about free will and divine determinism. Several thinkers have attempted to resist this conclusion. This essay critiques that view, with a special (...) focus on how it is developed in the work of W. Matthews Grant (2016, 2019). Grant contends that we can understand all of God’s activity as an exercise of divine “libertarian” free will and can construe God’s actions as nothing over and above the (created) effects brought about. I argue that Grant’s attempted reconciliation of human free will and universal divine causation fails, and on two counts. First, Grant does not succeed in presenting an account of the interaction of divine agency and created agency which avoids occasionalism; second, even if we assume Grant’s account successfully avoids the charge of occasionalism, it fails to reconcile divine agency with created free agency. The latter is illustrated by exploring the nature of the determination relation required by incompatibilist, agent-causation based accounts of free will. (shrink)

There has been much discussion recently of what has been labeled the “Brown-Boghossian-McKinsey”, “Brown-McKinsey” or sometimes just “McKinsey” arguments for the incompatibility of externalism and self-knowledge. However, while the three author's arguments have been treated as interchangeable, they are not identical. In particular, Brown’s and Boghossian’s arguments have a fairly serious flaw that cannot so easily be attributed to McKinsey. In what follows, I’ll (1) present a version of the ‘received’ “Brown-Boghossian-McKinsey” argument, (2) outline what I take to be (...) the most serious objection to it, (3) explain why this sort of objection does not seem, or do not seem immediately, to tell against McKinsey’s argument, and (4) suggest a number of alternative responses that might apply to McKinsey as well.

In this paper, I argue that perdurantism is incompatible with priority monism: the view that the universal mereological fusion, U, is fundamental. For the monist’s fundamental object can neither persist by being a trans-temporal object (i.e., a space-time ‘worm’) nor by being an instantaneous stage. If U persisted via being a worm, it would be grounded in its temporal parts, meaning that it would not be fundamental as it would not be ungrounded. If U were a stage, on the other (...) hand, it would face a problem from the possibility of ‘temporal gunk’. But if U persisted by neither being a worm nor a stage, then U could not persist via having temporal parts, and thus perdurantism would be false. Given that a similar combination of perdurantism and priority pluralism also faces a problem from temporal gunk, I conclude that perdurantism does not sit well with mereological based accounts of fundamentality.

The fact that there are quantum observables without a simultaneous measurement is one of the fundamental characteristics of quantum mechanics. In this work we expand the concept of joint measurability to all kinds of possible measurement devices, and we call this relation compatibility. Two devices are incompatible if they cannot be implemented as parts of a single measurement setup. We introduce also a more stringent notion of incompatibility, strong incompatibility. Both incompatibility and strong incompatibility are rigorously (...) characterized and their difference is demonstrated by examples. (shrink)

In 1985 the second author showed that if there is a proper class of measurable Woodin cardinals and $V^{B1} $ and $V^{B2} $ are generic extensions of V satisfying CH then $V^{B1} $ and $V^{B2} $ agree on all $\Sigma _1^2 $ -statements. In terms of the strong logic Ω-logic this can be reformulated by saying that under the above large cardinal assumption ZFC + CH is Ω-complete for $\Sigma _1^2 $ Moreover. CH is the unique $\Sigma _1^2 $ -statement (...) with this feature in the sense that any other $\Sigma _1^2 $ -statement with this feature is Ω-equivalent to CH over ZFC. It is natural to look for other strengthenings of ZFC that have an even greater degree of Ω-completeness. For example, one can ask for recursively enumerable axioms A such that relative to large cardinal axioms ZFC + A is Ω-complete for all of third-order arithmetic. Going further, for each specifiable segment $V_\lambda $ of the universe of sets (for example, one might take $V_\lambda $ to be the least level that satisfies there is a proper class of huge cardinals), one can ask for recursively enumerable axioms A such that relative to large cardinal axioms ZFC + A is Ω-complete for the theory of $V_\lambda $ . If such theories exist, extend one another, and are unique in the sense that any other such theory B with the same level of Ω-completeness as A is actually Ω-equivalent to A over ZFC, then this would show that there is a unique Ω-complete picture of the successive fragments of the universe of sets and it would make for a very strong case for axioms complementing large cardinal axioms. In this paper we show that uniqueness must fail. In particular, we show that if there is one such theory that Ω-implies CH then there is another that Ω-implies¬CH. (shrink)

Parents whose child is diagnosed with a serious disease such as trisomy 18 first rely on the medical community for an accurate description and prognosis. In the case of trisomy 18, however, many families are told the disease is “incompatible with life” even though some children with the condition live for several years. This paper considers parents’ response to current medical discourse concerning trisomy 18 by examining blogs written by the parents of those diagnosed. Using interpretive humanistic reading and foregrounding (...) Cathryn Molloy’s recuperative ethos theory, we find that parents demonstrate recuperative ethos in response to physicians’ descriptions of trisomy 18, particularly in rhetoric addressing survival, medicalized language, and religious and/or spiritual rhetoric. We argue that, by using language such as “incompatible with life,” physicians distance themselves from families, creating not care, but the very gulf that requires recuperation. We conclude that medical professionals would do well to engage with the trisomy 18 community—including learning from blogs and online forums— employ palliative care practices, and seek more accurate, descriptive language that is compatible with care.

This thesis suggests a novel problem for theists. This problem is that there is an incompatibility between free will theodicies and religious experience. Free will theodicies are responses to the problem of evil and religious experience is form of interaction between God and people. The free will theodicies that are discussed say that God gives us free will for two purposes. These purposes are to excuse God from direct responsibility for evil in the world and to act as a (...) qualifying factor in who goes where when we die. Religious experience, it will be argued, usually, if not always, gives recipients of religious experience moral benefits. The giving of moral benefits in religious experience acts to undermine the second purpose we are said to have been given free will and hence generates the incompatibility between free will theodicies and religious experience.

The following is an analysis of the relationship between incompatibility, conflict and breakdown. It is restricted to situations of a certain sort — to the isolation of the conditions under which breakdowns occur. These conditions are specific and defineable. Under certain circumstances incompatibilities and conflicts culminate in growth, under others in separation, under others in outright destruction of one of the incompatible elements, under others still in dominance-subserviance relationships and under others in breakdown. This is a matter of some (...) importance since influential current conceptions treat incompatibility and conflict as though they were uniform in outcome. The followers of Hegel regard them as always making for growth whereas certain contemporaries look upon them as the prime movers of breakdown and decline. The truth of the matter would seem to be that neither of these theories is correct. Conflicts vary, their consequences vary and the conditions under which they occur vary. For empirical analysis the important thing is the disengagement of the differences making for different culminations as well as the relations common to all; and the working out, as far as possible, of the way in which alterations in certain basic factors make for changes in result. A specific analysis of this sort may be valuable for foresight and even for a degree of control where the conditions are accessible to our manipulation. (shrink)

The article aims to investigate the problematic relationship between populism and democracy by comparing the conceptions of ‘the people’ and popular sovereignty which they presuppose. In the first two sections, the populist and the democratic ‘peoples’ are reconstructed, and the unbridgeable gap dividing them is highlighted. The discussion of the democratic people requires a concise analysis of the main contemporary democratic frameworks, including deliberative democracy, ‘neo-Roman’ republicanism, agonistic democracy. The article works out the implications of the incompatibility between the (...) two ‘sovereign peoples’ identified, and concludes that such an incompatibility undercuts the kinship of populism and democracy. While populism is often said to intertwine with democracy in some way, the article argues that it significantly departs from democratic theory and practice, and belongs to a distinct conceptual space. It cannot be made to overlap with ‘illiberal democracy’, a ‘democratic myth’, a crude electoral majoritarianism, nor does it amount to hiding undemocratic policies into properly democratic justifications. The boundary dividing populism and democracy, therefore, starts unfolding at the level of the conception of the people. While democratic theory invariably assumes a people intended as simultaneously heterogeneous and united, populism conceives of the people as a moral whole, internally undifferentiated, whose homogeneity and intrinsic righteousness preclude the task of specifying what popular sovereignty ultimately means. Such specification, on the other hand, is inescapable for any democrat assuming the people as a composite unity. The last section addresses four possible objections to the argument, variously formulated by Ernesto Laclau and by scholars approaching populism from a post-Laclauian or discursive-performative perspective.
