Our objective in this paper is twofold: first, we intend to address the tenability of the enactivist middle way between realism and idealism, as it is proposed in The Embodied Mind. We do so by taking the enactivist conception of bringing forth a world literally in three conceptual levels: enaction, niche construction and social construction. Based on this proposal, we claim that enactivism is compatible with the idea of an independent reality without committing to the claim that organisms have cognitive (...) access to a world composed of properties specified prior to any cognitive activity. Our second goal is to show that our literal interpretation of bringing forth a world not only sustains the legitimacy of the middle way, but it also allows us to revive the conception of evolution as natural drift—which is perhaps the least examined aspect of the original enactivist theory and is central to the understanding of cognition in an enactive way. Natural drift focuses on how structural couplings between organism and environment trigger viable pathways of maintenance and reproduction, instead of selecting the most adapted trait to a pregiven environment. Thus, although enactivists typically do not explore the consequences of their views regarding evolutionary dynamics, we show how natural drift provides a suitable starting point. (shrink)

Ecological-enactive approaches to cognition aim to explain cognition in terms of the dynamic coupling between agent and environment. Accordingly, cognition of one’s immediate environment depends on enaction and the picking up of affordances. However, ecological-enactive views supposedly fail to account for what is sometimes called “higher” cognition, i.e., cognition about potentially absent targets, which therefore can only be explained by postulating representational content. This challenge levelled against ecological-enactive approaches highlights a putative explanatory gap between basic and higher cognition. In this (...) paper, we examine scientific cognition—a paradigmatic case of higher cognition—and argue that it shares fundamental features with basic cognition, for enaction and affordance selection are central to the scientific enterprise. Our argument focuses on modeling, and on how models promote scientific understanding. We base our argument on a non-representational account of scientific understanding and on the material engagement theory, for models are hereby conceived as material objects designed for scientific engagements. Having done so, we conclude that the explanatory gap is significantly less threatening to the ecological-enactive approach than it might appear. (shrink)

In order to meet the explanatory challenge levelled against non-representationalist views on cognition, radical enactivists claim that cognition about potentially absent targets involves the socioculturally scaffolded capacity to manipulate public symbols. At a developmental scale, this suggests that higher cognition gradually emerges as humans begin to master language use, which takes place around the third year of life. If, however, it is possible to show that pre-linguistic infants represent their surroundings, then the radical enactivists’ explanation for the emergence of higher (...) cognition is defeated. In this paper, I critically assess experiments designed to show that pre-linguistic infants inherit representational abilities. I begin by outlining these experiments in Sect. 2. In Sect. 3, I argue that these experiments only succeed in supporting widespread representationalism by committing a particular kind of circular reasoning, which I call conjunctivist reasoning due to its origins in the debates about the nature of perception. I conclude by developing two independent yet congruent enactivist lines of interpretation for the experiments discussed in 2. I explain the infants’ responses to atypical experimental conditions based on agent-environment codetermination and then I argue that surprise behavior can be explained in terms of embodied habits and unfulfilled anticipation.

This paper intends to offer a critical evaluation of the role played by intuitions in the mainstream methodology in traditional analytic epistemology. The criticism directed to what I call methodology of evaluation by intuitions shows that epistemologists often idealize the reliability of intuitions when assessing a theory against potential counterexamples, ignoring that the disposition to answer intuitively to a case of concept attribution is bounded to the familiar dimension in which the relevant conceptual competence emerges. Thus, the reliability of intuitions (...) does not necessarily extend to far-fetched cases. Given that the assessment by our intuitions is not sufficient to decide for or against an epistemological theory, I offer a sketch for a pragmatic and naturalized conception of theoretical decision-making in epistemology.Key-words: Intuitions, Analytic epistemology, Conceptual abilities, Naturalism, Pragmatism.

It is common in the cognitive and computational sciences to regard virtual reality (VR) as composed of illusory experiences, given its immersive character. In this paper, we adopt an ecological-enactive perspective on cognition (Sect. 3) to evaluate the nature of VR and one’s engagement with it. Based on a post-cognitivist conception of illusion, we reject the commonly held assumption that virtual reality experiences (VREs) are illusory (Sect. 4). Our positive take on this issue is that VR devices, like other technological (...) devices, can be embodied during use, which is why they can be the source of experiences (Sect. 5). We then propose a new concept to interpret VREs, namely, _allusion_, which means that the subject acts _as if_ the virtual experiences are real (Sect. 6). This kind of engagement has a volitional aspect, which is evident in the onboarding of VR devices and which allows us to distinguish VREs from other experiences. We conclude that, even though we have experiences that afford certain interactions in VR, the strong continuity between cognitive and biological processes is not sustained therein. This characterizes a difference of kind—given the current state of technology—between VREs and fully fledged cognitive states, which nevertheless allows for constrained experimentation in cognitive science.

Rational beliefs and actions are typically evaluated against certain benchmarks, e.g., those of classical logic or probability theory. Rationality therefore is traditionally taken to involve some sort of reasoning, which in turn implies contentful cognition. Radically Enactive views of Cognition, on the other hand, claim that not all cognition is contentful. In order to show that rationality does not need to lie outside of REC’s scope of radicalizing cognition, I develop a Radically Enactive notion of Rationality, according to which rationality (...) is embodied, situated and contentless. For RER, an organism acts rationally insofar as it sustains a proficient interaction with its environment, which in turn requires the coordination of cognitive abilities in accordance with environmental constraints. Rationality is thus distinguished from reasoning, for reasoning is understood as a capacity to coordinate representational cognitive abilities. (shrink)

Assuming a radical stance on embodied cognition, according to which the information ac- quired through basic cognitive processes is not contentful (Hutto and Myin, 2013), and as- suming that perception is a source of rationally grounded knowledge (Pritchard, 2012), a pluralistic account of perceptual knowledge is developed. The paper explains: (i) how the varieties of perceptual knowledge fall under the same broader category; (ii) how they are subject to the same kind of normative constraints; (iii) why there could not be (...) a conflict between the different varieties of perceptual knowledge; and (iv) why the traditional episte- mological inquiry is inclined to overestimate the role of propositional perceptual knowledge.

Though there are many challenges to Ekman’s thesis that there are basic emotions with universal corresponding facial expressions, our main criticism revolves around the extent to which grounding situations alter how people read faces. To that end, we recruit testifying experimental studies that show identical faces expressing varying emotions when contextualized differently. Rather than dismissing these as illusions, we start with the position—generally favored by embodied thinkers—that situations are primary: they are where specifiable and hence knowable properties first show up. (...) We further argue that situationally inflected emotional expressions are informationally meaningful. We reject the idea that reading expressions is primarily about ascertaining internal mental states, arguing instead that people are registering overall situations when looking at faces. However, if mind is understood as a situated phenomenon that extends into active ecological frames, then one can still argue that mindreading is going on. Although we do not claim isolated things like cliffs or cars have agency, we speculate networked systems with cliffs, people, cars, bears, etc., collectively function with intentionality, more so if advancing a robust situated mind thesis, contra figures like Dennett who argue that people over-impute mind to things. Our position has practical implications insofar as it casts doubts on recent attempts to develop AI systems that extract emotional intent out of facial expressions since many of these systems are grounded on Ekman’s basic view.

Desde os anos 90, a corporeidade vem ocupando um papel cada vez mais central nas explicações das ciências cognitivas. Com isso, surgiram críticas contundentes, tanto do ponto de vista empírico quanto conceitual, à suposição de que a representação é a marca do mental. Apesar disso, cientistas cognitivos parecem relutar em desfazer- se do vocabulário representacionalista. Este artigo tenta lançar luz sobre a questão do suposto representacionalismo de um dos principais paradigmas das ciências cognitivas, o Processamento Preditivo, revisando argumentos pela interpretação (...) não- representacionalista de alguns de seus pontos, assim resgatando a ideia avançada pelas teorias da cognição corporificada segundo a qual a atividade exploratória de um organismo em seu ambiente não exige a geração de modelos representacionais acerca do ambiente.

Based on Pritchard's distinction between favoring and discriminating epistemic grounds, and on how those grounds bear on the elimination of skeptical possibilities, I present the dream argument as a moderate skeptical possibility that can be reasonably motivated. In order to block the dream argument skeptical conclusion, I present a version of phenomenological disjunctivism based on Noë's actionist account of perceptual consciousness. This suggests that perceptual knowledge is rationally grounded because it is a form of embodied achievement - what I call (...) embodied rationality -, which offers a way of dissolving the pseudo-problem of epistemic immodesty, namely, the seemingly counterintuitive thesis that one can acquire rationally grounded knowledge that one is not in a radical skeptical scenario.

Primeiro apresento as linhas gerais do programa de pesquisa sobre cognição corporificada. Em uma posição central nesse programa, está a tese de que a cognição atravessa cérebro, corpo e mundo – e que, portanto, atividades cognitivas não são eventos exclusivamente intracraniais que ocorrem pela manipulação de representações. Eu apresento a gênese histórica desse programa, a saber, o projeto autopoiético dos chilenos Humberto Maturana e Francisco Varela. Desse projeto, é possível atestar um plano de fundo antirrealista e construtivista, segundo o qual (...) a cognição é uma construção do mundo pelo organismo. Depois, eu apresento o fundamento teórico que recentemente tomou os holofotes do programa, a saber, o enativismo sensório-motor. Esse enativismo manifesta o compromisso com um realismo comedido, segundo o qual há estruturas objetivas a serem exploradas de acordo com a morfologia corpórea do organismo. Assim, observa-se uma tensão epistemológica no cerne do programa. Eu apresento uma possibilidade de resolução dessa tensão pela rejeição de uma das teses centrais do projeto autopoiético – a continuidade forte entre vida e cognição – e por uma melhor interpretação do que significa dizer que a cognição requer que o oragnismo “construa” o seu ambiente.

In this paper, I present a possible solution to the puzzle unveiled by Kornblith about the sources and the possibility of knowledge of epistemic norms. The puzzle is: if such norms cannot be discovered solely by reflection, and if there are correct ways of thinking and inferring, then such norms can only be discovered by investigating the world —a counterintuitive conclusion. To avoid skepticism about normativity, I argue that we create normative correctness and discover normative demands by investigating the world (...) and reflecting about our epistemic practices. This is done by an exposition of the method known as reflective equilibrium, which is defended against Kornblith’s thesis that the appeal to reflective equilibrium is doomed to failure because it implies reflection.

Information is a central notion for cognitive sciences and neurosciences, but there is no agreement on what it means for a cognitive system to acquire information about its surroundings. In this paper, we approximate three influential views on information: the one at play in ecological psychology, which is sometimes called information for action; the notion of information as covariance as developed by some enactivists, and the idea of information as minimization of uncertainty as presented by Shannon. Our main thesis is (...) that information for action can be construed as covariant information, and that learning to perceive covariant information is a matter of minimizing uncertainty through skilled performance. We argue that the agent’s cognitive system conveys information for acting in an environment by minimizing uncertainty about how to achieve her intended goals in that environment. We conclude by reviewing empirical findings that support our view and by showing how direct learning, seen as instance of ecological rationality at work, is how mere possibilities for action are turned into embodied know-how. Finally, we indicate the affinity between direct learning and sense-making activity. (shrink)

In this paper, I argue that knowledge is dimly luminous. That is: if a person knows that p, she knows how she knows that p. The argument depends on a safety-based account of propositional knowledge, which is salient in Williamson’s critique of the ‘KK’ principle. I combine that account with non-intellectualism about knowledge-how – according to which, if a person knows how to φ, then in nearly all (if not all) nearby possible worlds in which she φes in the same (...) way as in the actual world, she only φes successfully. Thus, the possession of first-order propositional knowledge implies secondorder practical knowledge, and this can be iterated. Because of the assumed nonintellectualism about know-how, dim luminosity does not imply bright luminosity about knowledge, which is expressed by the traditional KK principle. I conclude by considering some potential counterexamples to the view that knowledge is dimly luminous. (shrink)

I advance the Radically Enactive Cognition (REC) program by developing Hutto & Satne’s (2015) and Hutto & Myin’s (2017) idea that contentful cognition emerges through sociocultural activities, which require a contentless form of intentionality. Proponents of REC then face a functional challenge: what is the function of higher cognitive skills, given the empirical findings that engaging in higher-cognitive activities is not correlated with cognitive amelioration (Kornblith, 2012)? I answer that functional challenge by arguing that higher cognition is an adaptive tool (...) of the social systems we are embedded in, therefore, it is not necessarily aimed at achieving better cognitive states. In order to do so, I suggest interpreting key insights from autopoietic enactivism through REC lenses. (shrink)

ABSTRACT I propose a middle-ground between a perceptual model of self-knowledge, according to which the objects of self-awareness are accessed through some kind of causal mechanism, and a rationalist model, according to which self-knowledge is constituted by one's rational agency. Through an analogy with the role of the exercises of sensorimotor abilities in rationally grounded perceptual knowledge, self-knowledge is construed as an exercise of action-oriented and action-orienting abilities. This view satisfies the privileged access condition usually associated with self-knowledge without entailing (...) an insurmountable gap between self- knowledge and knowledge of other minds. RESUMO Proponho um meio-termo entre um modelo perceptual de autoconhecimento, segundo o qual os objetos de autoconhecimento são acessadas mediante um tipo de mecanismo causal, e um modelo racionalista, segundo o qual o autoconhecimento é constituído pela agência racional. Por analogia ao papel que o exercício de habilidades sensório-motoras desempenham no conhecimento perceptual racionalmente fundado, autoconhecimento é entendido como um exercício de habilidades que são orientadas pela e orientam a ação. Essa imagem satisfaz a condição de acesso privilegiado que geralmente é associada ao autoconhecimento sem implicar uma lacuna intransponível entre autoconhecimento e conhecimento de outras mentes.

In the article “Why are we our brain: enactivism put into question” (this volume), Pereira and collaborators raise a battery of criticisms of enactivism, which is a family of approaches in the cognitive sciences that gives centrality to the body and to the autonomous action of organisms in explanations of their cognitive processes. The authors’ attacks target some central concepts of the enactivist proposal, such as practical knowledge, embodiment (or corporeity) and sensory-motor regularities. I argue that the criticisms by Pereira (...) et al. do not proceed for different reasons: some assume what they want to prove, others give excessive weight to intuitions about fictional scenarios and, finally, others attack scarecrows that do not represent the enactivist positions. None of the points I raise in defense of enactivism are new, but I consider it important to make them explicit in order to make the debate on the philosophy of cognitive sciences clearer. (shrink)

The aim of this paper is two-fold: first, it is intended to articulate theses that are often assessed independently, thus showing that a strong version of epistemological disjunctivism about perceptual knowledge implies a transformative conception of rationality. This entails that individuals in skeptical scenarios could not entertain rational thoughts about their environment, for they would fail to have perceptual states. The secondary aim is to show that this consequence is not a sufficient reason to abandon the variety of disjunctivism presented. (...) The argument for this claim depends on the assessment of rationality attributions to subjects in plausible cases of illusion and some clinical cases of hallucination. RESUMO Este artigo tem dois objetivos: primeiramente, pretende-se articular teses que são frequentemente avaliadas independentemente, mostrando com isso que uma versão robusta do disjuntivismo epistemológico sobre conhecimento perceptual implica uma concepção transformativa da racionalidade. Uma consequência disso é que indivíduos em cenários céticos não poderiam entreter pensamentos racionais sobre o ambiente em que habitam, pois eles não possuiriam estados perceptuais. Em segundo lugar, argumenta-se que a consequência delineada acima não é uma razão suficiente para rejeitar o disjuntivismo tal como apresentado. Esse argumento depende da avaliação de atribuições de racionalidade a indivíduos em casos plausíveis de ilusão e em alguns casos clínicos de alucinação. (shrink)

Na filosofia analítica contemporânea, enquanto alguns epistemólogos afirmam que a reflexão – entendida como autoexame crítico das crenças – é uma condição necessária para a atribuição de estados epistêmicos valiosos, outros rejeitam essa afirmação e sustentam que os filósofos tendem a superestimar o valor da reflexão em seus relatos de fenômenos epistemológicos. Neste ensaio, apresentamos um breve panorama desse debate e indicamos os elementos que constituem o desacordo entre epistemólogos. Nosso diagnóstico é que, a despeito do radical desacordo, essas posições (...) convergem porque tratam a reflexão de um ponto de vista individualista, uma vez que a definem como uma performance metacognitiva privada de um agente sobre os próprios estados epistêmicos. Além de ser um motivo de desacordo, essa concepção de reflexão pode ser a razão de uma compreensão equivocada dos epistemólogos sobre o lugar e valor da reflexão. (shrink)

Enactivism is a family of theories that construe action as constitutive of cognition and reject the need to postulate representations in order to explain all cognitive activities. Acknowledging a biologically basic, non-representational mode of cognition, however, raises the question of how to explain higher or more complex cognitive acts, what we call explanatory integration challenge. In this paper, we critically discuss some attempts to meet that challenge through scaling up basic cognition and through scaling down complex cognition within the enactivist (...) research program.

Persons with borderline personality disorder are often described as affected by extreme emotional fluctuations and by the sudden emergence of uncontrollable and disproportionate emotional reactions. Borderline persons frequently experience their own self as dim and fuzzy, are deprived of a stable sense of identity and unable to be steadily involved in a given life project. We will interpret these typical features as fluctuations between a clearly normative emotion such as anger and the more diffuse and confusing background of bad moods (...) like dysphoria. Our main focus will be on dysphoria. The intentional structure that characterizes much of human emotional experience, we shall argue, is absent in dysphoria. If we imagine emotions as fluxes of intentionality that innervate the body and connect it to the world, dysphoria is empty intentionality, so to speak, devoid of the moderating power of language and representation. Dysphoria exerts a centrifugal force which fragments the borderline person's representations of herself and of others, inducing a painful experience of incoherence and inner emptiness, a feeling of uncertainty and inauthenticity in interpersonal relationships, and an excruciating sense of futility and inanity of life. But it also entails a sense of vitality, although a disorganized, aimless, and explosive one -- a desperate vitality. (shrink)

According to Leibniz’s infinite-analysis account of contingency, any derivative truth is contingent if and only if it does not admit of a finite proof. Following a tradition that goes back at least as far as Bertrand Russell, several interpreters have been tempted to explain this biconditional in terms of two other principles: first, that a derivative truth is contingent if and only if it contains infinitely complex concepts and, second, that a derivative truth contains infinitely complex concepts if and only (...) if it does not admit of a finite proof. A consequence of this interpretation is that Leibniz’s infinite-analysis account of contingency falls prey to Robert Adams’s Problem of Lucky Proof. I will argue that this interpretation is mistaken and that, once it is properly understood how the idea of an infinite proof fits into Leibniz’s circle of modal notions, the problem of lucky proof simply disappears.

Euler developed a program which aimed to transform analysis into an autonomous discipline and reorganize the whole of mathematics around it. The implementation of this program presented many difficulties, and the result was not entirely satisfactory. Many of these difficulties concerned the integral calculus. In this paper, we deal with some topics relevant to understand Euler’s conception of analysis and how he developed and implemented his program. In particular, we examine Euler’s contribution to the construction of differential equations and his (...) notion of indefinite integrals and general integrals. We also deal with two remarkable difficulties of Euler’s program. The first concerns singular integrals, which were considered as paradoxical by Euler since they seemed to violate the generality of certain results. The second regards the explicitly use of the geometric representation and meaning of definite integrals, which was gone against his program. We clarify the nature of these difficulties and show that Euler never thought that they undermined his conception of mathematics and that a different foundation was necessary for analysis. (shrink)

Cross-temporal grounding is a type of grounding whereby present facts about the past (for example that Caesar was alive) are explained in terms of past facts (for example that Caesar is alive) rather than in terms of other present facts. This paper lays the foundations for a theory of cross-temporal grounding. After introducing the general idea of a type of grounding connecting facts to past facts, we offer two arguments that past-directed facts require cross-temporal grounds—the ‘argument from intimacy’ and the (...) ‘argument from past explanation’. We then go on to show that cross-temporal grounding statements can be understood as instances of a type of explanation which is perfectly legitimate and intelligible, even if somewhat unusual. Finally, we explain how the logic of grounding can be extended to accommodate cross-temporal grounding statements. (shrink)

The paper reconstructs the concept of culture that emerges from Heinrich Rickert?s neo-Kantianism, uncovering its major historical-problematic, methodological, and philosophical implications. The central theme of the first section is the idea that modern culture is uniquely characterized by?fragmentation?. It also unpacks the programme of Rickert?s philosophy of culture, which pursues the task of reconstructing the lost unity of culture. The second section explains the methodological implications of the problematic relationship between value and reality established in cultural goods and evaluations. Finally, (...) the third section reconstructs the Rickertian system of values, with its peculiar effort to reconcile historicity and value absoluteness. The last part develops a critical discussion of the Rickertian project. (shrink)

Riassunto: Questo lavoro sviluppa due elementi, apparentemente lontani, ma per alcuni aspetti non secondari, convergenti. Per un verso l’attenzione è rivolta all’origine delle regole che disciplinano il comportamento sociale umano, oltrepassando le regole di matrice istituzionale e convenzionale, che sono spesso considerate le più nobili e le più umane, nel tentativo di far affiorare le regole più remote del nostro agire, legate al patrimonio genetico degli individui della nostra specie, al parlamento dei nostri istinti, sviluppatisi durante l’evoluzione filogenetica. Lungo questo (...) primo tratto del percorso l’articolo fa riferimento in particolare al pensiero di Konrad Lorenz e della sua scuola. Per altro verso, si seguono le tracce del pensiero etico di Lévinas, soffermandosi su alcuni punti fondamentali: il volto dell’altro, la passività, la responsabilità, al fine di porre in evidenza come tra il filosofo e l’etologo, pur nelle evidenti differenze di linguaggio, di approccio e di orizzonti, siano ravvisabili tratti e conclusioni comuni. Parole chiave: Alterità; Relazione; Istinto; Etica; Responsabilità Autrui: Ethics and anthropology in Lévinas: This paper moves along two seemingly distant paths, that turn out to converge in some significant ways. The first path leads us to the origin of what are often considered the most noble and essentially human principles that regulate our social behaviour, going beyond institutional and conventional norms. This allows us to highlight the deepest and most evolutionarily remote rules of human behaviour, related to our genetic code and instincts, which developed over phylogenetic evolution. As we move along this first path, we pay special attention to the work of Konrad Lorenz and his school. The second path follows the traces of Lévinas’ ethical thought, dwelling on some fundamental issues: the face of the other, passivity, and responsibility, and helps us shed light on some ideas and conclusions that are common to the philosopher and the ethologist, despite their clear differences in language, approach, and horizons. We hope this will show how the insights of each can be used to support of the theories of the other. Keywords: Otherness: relationship; Instinct; Ethics; Responsibility. (shrink)

In this paper, I will defend a communitarian perspective on the so-called “hinge propositions” (hinges, for short). Accordingly, I will argue that hinges play a normative role, in the sense that, among other things, they govern the mechanisms of social inclusion/exclusion. In particular, I will examine the so-called “religious hinges”; and I will argue that such hinges, being the product of mere indoctrination, are particularly effective in shaping boundaries among communities. Finally, with the help of Peter Munz's theory of altruism, (...) I will attempt to explain why religious hinges play the role they do. (shrink)

Martin-Löf Type Theory is both an important and practical formalization and a focus for a charismatic view of the foundations of mathematics.

In this article, we shall study the mechanism of the Shroud body image formation with the help of both natural sciences and religion. The various possibilities can be divided into three groups of hypothesis: the first one is that of the fake, the second is the miracle and the third one of the natural event. The first hypothesis is discarded by the interdisciplinary work of the STURP team. Their results do not support the hypothesis that the blood stains and the (...) body image are due to a forger. In our opinion, even if the Miracle by God is possible, the proposed hypotheses of the supernatural event are theologically unacceptable. So, the natural one remains well supported by the “Ockham’s razor”. Obviously, this last model must be verified by experimental evidence. However, this result is not contrary to the hypothesis that the body image is the one of the Nazarene. (shrink)

Exploration into the concept, origins and meaning of place, taking Delphi, Rome and Jerusalem as principle examples.

In the second half of the seventeenth century, philosophy teaching in the Scottish universities gradually moved from scholasticism to Cartesianism. Robert Forbes, regent at Marischal College and King's College, Aberdeen, was a strenuous opponent of Descartes. The analysis of the philosophy of Forbes and of his teacher Patrick Gordon sheds light on the relationship between Scottish Reformed scholasticism and the reception of Descartes in Scotland.

In intuitionistic generalized predicative systems as constructive set theory, or constructive type theory, two categories have been proposed to play the role of the category of locales: the category FSp of formal spaces, and its full subcategory FSpi of inductively generated formal spaces. Considered in impredicative systems as the intuitionistic set theory IZF, FSp and FSpi are both equivalent to the category of locales. However, in the mentioned predicative systems, FSp fails to be closed under basic constructions such as that (...) of finite products, while FSpi is complete , but does not contain some naturally occurring classes of formal spaces. Moreover, completeness of FSpi only holds under the assumption of strong principles for the existence of inductively defined sets.In this paper, working in the context of constructive set theory, the category ImLoc of imaginary locales is introduced. ImLoc is complete already over weak formulations of constructive set theory, contains FSp and FSpi as full subcategories, and, as FSp and FSpi, is equivalent to the category of locales in IZF.Applications of the concept of imaginary locale to a proof of a point-free version of Tychonoff embedding theorem, and to set-representation theorems, are then presented.
