Wittgenstein’s concepts shed light on the phenomenon of schizophrenia in at least three different ways: with a view to empathy, scientific explanation, or philosophical clarification. I consider two different “positive” wittgensteinian accounts―Campbell’s idea that delusions involve a mechanism of which different framework propositions are parts, Sass’ proposal that the schizophrenic patient can be described as a solipsist, and a Rhodes’ and Gipp’s account, where epistemic aspects of schizophrenia are explained as failures in the ordinary background of certainties. I argue that (...) none of them amounts to empathic-phenomenological understanding, but they provide examples of how philosophical concepts can contribute to scientific explanation, and to philosophical clarification respectively.

Recently, there has been increasing interest in methodological aspects of advanced imaging, including the role of guidelines, recommendations, and experts’ consensus, the practice of self-referral, and the risk of diagnostic procedure overuse. In a recent Delphi study of the European Association for Nuclear Medicine (EANM), panelists were asked to give their opinion on 47 scientific questions about imaging in prostate cancer. Nine additional questions exploring the experts’ attitudes and opinions relating to the procedure of consensus building itself were also included. (...) The purpose was to provide insights into the mechanism of recommendation choice and consensus building as seen from the experts’ point of view. Results: Regarding the factors likely to influence the willingness to refer a patient for imaging, the most voted were incorporation into guidelines and data from scientific literature, while personal experience and personal relationship were chosen by a small minority. Regarding the recommendations more relevant to prescribe an imaging procedure, it resulted the incorporation into guidelines promoted by scientific societies (59% of votes); these guidelines also resulted the more trusted. With respect to patients’ preferences considered when prescribing an imaging procedure, the most voted was accuracy, resulted more important than easy access and time to access to the procedure. The majority of the experts expressed the opinion that there is a scarce use of imaging procedures in prostate cancer. With respect to the most relevant factor to build consensus, it resulted the transparency of the process (52% of votes), followed by multidisciplinarity of contributors. The main obstacle to incorporation of modern imaging procedures into guidelines resulted the lack of primary literature on clinical impact. Conclusions: Firstly, the panelists portray themselves as having Evidence-Based Medicine oriented and scientifically inclined attitudes and preferences. Secondly, guidelines and recommendations from scientific societies, especially clinical ones, are positively taken into account as factors influencing decisions, but panelists tend to consider their own appraisal of the scientific literature as more relevant. Thirdly, in respect of overuse, panelists do not think that advanced diagnostic procedures are overutilized in the specific case of Prostate Cancer, but rather they are underutilized. (shrink)

At present, psychiatric disorders are characterized descriptively, as the standard within the scientific community for communication and, to a certain extent, for diagnosis, is the DSM, now at its fifth edition. The main reasons for descriptivism are the aim of achieving reliability of diagnosis and improving communication in a situation of theoretical disagreement, and the Ignorance argument, which starts with acknowledgment of the relative failure of the project of finding biomarkers for most mental disorders. Descriptivism has also the advantage of (...) capturing the phenomenology of mental disorders, which appears to be essential for diagnosis, though not exhaustive of the nature of the disease. I argue that if we rely on the distinction between conceptions (procedures of identification) and concepts (reference-fixing representations), which was introduced in the philosophical debate on the nature of concepts, we may understand a limited but valid role for descriptive characterizations, and reply to common objections addressed by those who advocate a theoretically informed approach to nosology.

Riassunto: In questo contributo analizzeremo il criterio del danno, presente nella definizione generale di disturbo mentale del DSM. La questione ha rilevanza sia da un punto di vista filosofico, perché il danno è una componente normativa e valoriale, non oggettiva, sia da un punto di vista clinico, perché chi ha difeso il criterio del danno ha spesso sostenuto che in sua assenza avremmo troppi falsi positivi. Infine, ha importanza dal punto di vista socio-sanitario in relazione al rapporto tra la psichiatria (...) e la medicina non psichiatrica, nello specifico tra il DSM e l’ICD. Sosterremo che ci sono buone ragioni per non mantenere il danno come criterio necessario nella definizione generale del disturbo mentale. Dopo una breve introduzione, forniremo una panoramica storica sul ruolo del criterio del danno nelle varie edizioni del DSM. Successivamente si illustrerà la principale obiezione contro l’inclusione del criterio del danno nella definizione generale di disturbo mentale, ossia il problema dei falsi negativi, per poi presentare e discutere ulteriori ragioni – medico-pratiche e concettuali – che depongono a sfavore dell’attribuzione di un forte peso al criterio del danno. In sede conclusiva ribadiamo come la decisione presa dalla task force del DSM-5 di escludere il criterio del danno dalla definizione generale di disturbo mentale debba essere sostenuta. Parole chiave: Danno; Disabilità; Disagio; Disturbo mentale; DSM “Harm” as Criterion for the Definition of Mental Disease in DSM. Some Epistemological Reflections: In this paper, we analyse the harm requirement in the general definition of mental disorder in the Diagnostic and Statistical Manual for Mental Disorders. This issue has both philosophical and clinical relevance: on the one hand the harm requirement is a normative, value-laden, non-objective component in the definition of mental disorder; on the other hand, the harm requirement has often been defended on the grounds that it prevents an increase in false positives. The issue is also important in assessing the relationship between psychiatry and somatic medicine, more precisely, between the DSM and the International Classification of Diseases. We argue that there are good reasons not to maintain the harm requirement in the general definition of mental disorder. After a brief introduction, we overview the history of the harm requirement across the various editions of the DSM. Then, we examine the main objection to the inclusion of the harm requirement in the general definition of mental disorder, that is, the problem of false negatives, and also present several other points – both practical and conceptual – that help demonstrate why the harm requirement is inadequate as a definiens of mental disorder. To conclude, we stress that the decision of the DSM-5 task force not to regard the harm requirement as a necessary component of mental disorder should be endorsed. Keywords: Harm; Disability, Distress; Mental Disorder; DSM. (shrink)

This paper explores the possibility of resisting meaning scepticism – the thesis that there are many alternative incompatible assignments of reference to each of our terms - by appealing to the idea that the nature of reference is to maximize knowledge. If the reference relation is a knowledge maximizing-relation, then some candidate referents are privileged among the others - i.e., those referents we are in a position to know about – and a positive reason against meaning scepticism is thus individuated. (...) A knowledge-maximizing principle on the nature of reference was proposed by Williamson in a recent paper (Williamson 2005). According to Williamson, such a principle would count as a defeasible reason for thinking that most of our beliefs tend to be true. My paper reverses Williamson’s dialectic, and argues that reference is knowledge-maximizing from the premise that most of our beliefs tend to be true. (shrink)

The latest edition of the Diagnostic and Statistical Manual of Mental Disorders included the Social Communication Disorder as a new mental disorder characterized by deficits in pragmatic abilities. Although the introduction of SPCD in the psychiatry nosography depended on a variety of reasons—including bridging a nosological gap in the macro-category of Communication Disorders—in the last few years researchers have identified major issues in such revision. For instance, the symptomatology of SPCD is notably close to that of Autism Spectrum Disorder. This (...) opens up the possibility that individuals with very similar symptoms can be diagnosed differently and receive different clinical treatments and social support. The aim of this paper is to review recent debates on SPCD, particularly as regards its independence from ASD. In the first part, we outline the major aspects of the DSM-5 nosological revision involving ASD and SPCD. In the second part, we focus on the validity and reliability of SPCD. First, we analyze literature on three potential validators of SPCD, i.e., etiology, response to treatment, and measurability. Then, we turn to reliability issues connected with the introduction of the grandfather clause and the use of the concepts of spectrum and threshold in the definition of ASD. In the conclusion, we evaluate whether SPCD could play any role in contemporary psychiatry other than that of an independent mental disorder and discuss the role that non-epistemic factors could play in the delineation of the future psychiatry nosography.

G.E. Moore, more than either Bertrand Russell or Ludwig Wittgenstein, was chiefly responsible for the rise of the analytic method in twentieth-century philosophy. This selection of his writings shows Moore at his very best. The classic essays are crucial to major philosophical debates that still resonate today. Amongst those included are: * A Defense of Common Sense * Certainty * Sense-Data * External and Internal Relations * Hume's Theory Explained * Is Existence a Predicate? * Proof of an External World (...) In addition, this collection also contains the key early papers in which Moore signals his break with idealism, and three important previously unpublished papers from his later work which illustrate his relationship with Wittgenstein.

Advanced medical imaging, such as CT, fMRI and PET, has undergone enormous progress in recent years, both in accuracy and utilization. Such techniques often bring with them an illusion of immediacy, the idea that the body and its diseases can be directly inspected. In this paper we target this illusion and address the issue of the reliability of advanced imaging tests as knowledge procedures, taking positron emission tomography in oncology as paradigmatic case study. After individuating a suitable notion of reliability, (...) we argue that PET is a highly theory-laden and non-immediate knowledge procedure, in spite of the photographic-like quality of the images it delivers; the diagnostic conclusions based on the interpretation of PET images are population-dependent; PET images require interpretation, which is inherently observer-dependent and therefore variable. We conclude with a three-step methodological proposal for enhancing the reliability of advanced medical imaging. (shrink)

The general concept of mental disorder specified in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders is definitional in character: a mental disorder might be identified with a harmful dysfunction. The manual also contains the explicit claim that each individual mental disorder should meet the requirements posed by the definition. The aim of this article is two-fold. First, we shall analyze the definition of the superordinate concept of mental disorder to better understand what necessary criteria actually (...) characterize such a concept. Second, we shall consider the concepts of some individual mental disorders and show that they are in tension with the definition of the superordinate concept, taking pyromania and narcissistic personality disorder as case studies. Our main point is that an unexplained and not-operationalized dysfunction requirement that is included in the general definition, while being systematically violated by the diagnostic criteria of specific mental disorders, is a logical error. Then, either we unpack and operationalize the dysfunction requirement, and include explicit diagnostic criteria that can actually meet it, or we simply drop it. (shrink)

Are concepts stable entities, unchanged from context to context? Or rather are they context-dependent structures, created on the fly? We argue that this does not constitute a genuine dilemma. Our main thesis is that the more a pattern of features is general and shared, the more it qualifies as a concept. Contextualists have not shown that conceptual structures lack a stable, general core, acting as an attractor on idiosyncratic information. What they have done instead is to give a contribution to (...) the comprehension of how conceptual structure organized around such a stable core can produce contextually appropriate representations on demand.

I argue that a concept is applied correctly when it is applied to the kind
of things it is the concept of. Correctness as successful kind-tracking is
fulfilling an externally and naturalistically individuated standard. And the normative aspect of concept-application so characterized depends on the relational (non-individualistic) feature of conceptual content. I defend this view against two objections. The first is that norms should provide justifications for action, and the second involves a version of the thesis of indeterminacy of reference.

In the ongoing pandemic, death statistics influence people’s feelings and government policy. But when does COVID-19 qualify as the cause of death? As philosophers of medicine interested in conceptual clarification, we address the question by analyzing the World Health Organization’s rules for the certification of death. We show that for COVID-19, WHO rules take into account both facts and values.

We raise a problem of applicability of RCTs to validate nuclear diagnostic imaging tests. In spite of the wide application of PET and other similar techniques that use radiopharmaceuticals for diagnostic purposes, RCT-based evidence on their validity is sparse. We claim that this is due to a general conceptual problem that we call Prevalence of Treatment, which arises in connection with designing RCTs for testing any diagnostic procedure in the present context of medical research, and is particularly apparent in this (...) case. We also identify three practical reasons why RCTs do not qualify as the best option for PET validation, which have to do with specific characteristics of nuclear diagnostic imaging, and of radiopharmaceuticals. The paper is meant to contribute both to the philosophical discussion on the EBM hierarchy of evidence, and on the specific debate on radiopharmaceuticals in nuclear medicine. (shrink)

This commentary focuses on Machery's eliminativist claim, that ought to be eliminated from the theoretical vocabulary of psychology because it fails to denote a natural kind. I argue for the more traditional view that concepts are a functional kind, which provides the simplest account of the empirical evidence discussed by Machery.

An important contribution to the foundations of probability theory, statistics and statistical physics has been made by E. T. Jaynes. The recent publication of his collected works provides an appropriate opportunity to attempt an assessment of this contribution.

In this paper we focus on some new normativist positions and compare them with traditional ones. In so doing, we claim that if normative judgments are involved in determining whether a condition is a disease only in the sense identified by new normativisms, then disease is normative only in a weak sense, which must be distinguished from the strong sense advocated by traditional normativisms. Specifically, we argue that weak and strong normativity are different to the point that one ‘normativist’ label (...) ceases to be appropriate for the whole range of positions. If values and norms are not explicit components of the concept of disease, but only intervene in other explanatory roles, then the concept of disease is no more value-laden than many other scientific concepts, or even any other scientific concept. We call the newly identified position “value-conscious naturalism” about disease, and point to some of its theoretical and practical advantages. (shrink)

Health care systems can positively influence our personal decision-making and health-related behavior only if we trust them. I propose a conceptual analysis of the trust relation between the public and a healthcare system, drawing from healthcare studies and philosophical proposals. In my account, the trust relation is based on an epistemic component, epistemic authority, and on a value component, the benevolence of the healthcare system. I argue that it is also modified by the vulnerability of the public on healthcare matters, (...) and by the system’s credibility. I apply my proposed analysis of public trust in health care systems to the phenomenon of vaccine hesitancy, a tendency to question vaccine policies, and to seek alternative vaccine schedules or to refuse vaccination. Understanding the role of trust and its components can be key to understanding the phenomenon. (shrink)

Is God's foreknowledge compatible with human freedom? One of the most attractive attempts to reconcile the two is the Ockhamistic view, which subscribes not only to human freedom and divine omniscience, but retains our most fundamental intuitions concerning God and time: that the past is immutable, that God exists and acts in time, and that there is no backward causation. In order to achieve all that, Ockhamists distinguish ‘hard facts’ about the past which cannot possibly be altered from ‘soft facts’ (...) about the past which are alterable, and argue that God's prior beliefs about human actions are soft facts about the past.

The general definition of mental disorder stated in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders seems to identify a mental disorder with a harmful dysfunction. However, the presence of distress or disability, which may be bracketed as the presence of harm, is taken to be merely usual, and thus not a necessary requirement: a mental disorder can be diagnosed as such even if there is no harm at all. In this paper, we focus on the (...) harm requirement. First, we clarify what it means to say that the harm requirement is not necessary for defining the general concept of mental disorder. In this respect, we briefly examine the two components of harm, distress and disability, and then trace a distinction between mental disorder tokens and mental disorder types. Second, we argue that the decision not to regard the harm requirement as a necessary criterion for mental disorder is tenable for a number of practical and theoretical reasons, some pertaining to conceptual issues surrounding the two components of harm and others pertaining to the problem of false negatives and the status of psychiatry vis-à-vis somatic medicine. However, we believe that the harm requirement can be maintained among the specific diagnostic criteria of certain individual mental disorders. More precisely, we argue that insofar as the harm requirement is needed among the specific diagnostic criteria of certain individual mental disorders, it should be unpacked and clarified. (shrink)

What is a natural kind ? As we shall see, the concept of a natural kind has a long history. Many of the interesting doctrines can be detected in Aristotle, were revived by Locke and Leibniz, and have again become fashionable in recent years. Equally there has been agreement about certain paradigm examples: the kinds oak, stickleback and gold are natural kinds, and the kinds table, nation and banknote are not. Sadly agreement does not extend much further. It is impossible (...) to discover a single consistent doctrine in the literature, and different discussions focus on different doctrines without writers or readers being aware of the fact. In this paper I shall attempt to find a defensible distinction between natural and non-natural kinds. (shrink)

In this philosophy classic, which was first published in 1951, E. R. Dodds takes on the traditional view of Greek culture as a triumph of rationalism. Using the analytical tools of modern anthropology and psychology, Dodds asks, "Why should we attribute to the ancient Greeks an immunity from 'primitive' modes of thought which we do not find in any society open to our direct observation?" Praised by reviewers as "an event in modern Greek scholarship" and "a book which it would (...) be difficult to over-praise," _The Greeks and the Irrational _was Volume 25 of the Sather Classical Lectures series.

Philosophers of medicine have formulated different accounts of the concept of disease. Which concept of disease one assumes has implications for what conditions count as diseases and, by extension, who may be regarded as having a disease and for who may be accorded the social privileges and personal responsibilities associated with being sick. In this article, we consider an ideal diagnostic test for coronavirus disease 2019 infection with respect to four groups of people—positive and asymptomatic; positive and symptomatic; negative; and (...) untested—and show how different concepts of disease impact on the disease and sickness judgements for these groups. The suggestion is that sickness judgements and social measures akin to those experienced during the current COVID-19 outbreak presuppose a concept of disease containing social harm as a component. We indicate the problems that arise when adopting this kind of disease concept beyond a state of emergency. (shrink)

The strong weak truth table (sw) reducibility was suggested by Downey, Hirschfeldt, and LaForte as a measure of relative randomness, alternative to the Solovay reducibility. It also occurs naturally in proofs in classical computability theory as well as in the recent work of Soare, Nabutovsky, and Weinberger on applications of computability to differential geometry. We study the sw-degrees of c.e. reals and construct a c.e. real which has no random c.e. real (i.e., Ω number) sw-above it.

How could the self be a substance? There are various ways in which it could be, some familiar from the history of philosophy. I shall be rejecting these more familiar substantivalist approaches, but also the non-substantival theories traditionally opposed to them. I believe that the self is indeed a substance—in fact, that it is a simple or noncomposite substance—and, perhaps more remarkably still, that selves are, in a sense, self-creating substances. Of course, if one thinks of the notion of substance (...) as an outmoded relic of prescientific metaphysics—as the notion of some kind of basic and perhaps ineffable stuff —then the suggestion that the self is a substance may appear derisory. Even what we ordinarily call ‘stuffs’—gold and water and butter and the like—are, it seems, more properly conceived of as aggregates of molecules or atoms, while the latter are not appropriately to be thought of as being ‘made’ of any kind of ‘stuff’ at all. But this only goes to show that we need to think in terms of a more sophisticated notion of substance—one which may ultimately be traced back to Aristotle's conception of a ‘primary substance’ in the Categories , and whose heir in modern times is W. E. Johnson's notion of the ‘continuant’. It is the notion, that is, of a concrete individual capable of persisting identically through qualitative change, a subject of alterable predicates that is not itself predicable of any further subject.

O presente texto procura acompanhar alguns aspectos da reconstrução sartreana das relações entre indivíduo e história, tentando mostrar que a fenomenologia e o materialismo dialético comparecem nessa proposta de conhecimento e que é a convergência das duas perspectivas que permite, contemplando adequadamente a universalidade e a singularidade, descrever e compreender dialeticamente o modo histórico de produção da identidade individual.

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

Why does the problem of free will seem so intractable? I surmise that in large measure it does so because the free will debate, at least in its modern form, is conducted in terms of a mistaken approach to causality in general. At the heart of this approach is the assumption that all causation is fundamentally event causation. Of course, it is well-known that some philosophers of action want to invoke in addition an irreducible notion of agent causation, applicable only (...) in the sphere of intelligent agency. But such a view is generally dismissed as incompatible with the naturalism that has now become orthodoxy amongst mainstream analytical philosophers of mind. What I want to argue is that substances, not events, are the primary relata of causal relations and that agent causation should properly be conceived of as a species of substance causation. I shall try to show that by thus reconceiving the nature of causation and of agency, the problem of free will can be made more tractable. I shall also argue for a contention that may seem even less plausible at first sight, namely, that such a view of agency is perfectly compatible with a volitionist theory of action. (shrink)

If one is an egalitarian, what should one want to equalize? Opportunities or outcomes? Resources or welfare? These positions are usually conceived to be very different. I argue in this paper that the distinction is misconceived: the only coherent conception of resource equality implies welfare equality, in an appropriately abstract description of the problem. In this section, I motivate the program which the rest of the paper carries out.

E-Z Reader 7 is a processing model of eye-movement control. One constraint imposed on the model is that high-level cognitive processes do not influence eye movements unless normal reading processes are disturbed. I suggest that this constraint is unnecessary, and that the model provides a sensible architecture for explaining how both low- and high-level processes influence eye movements.

Hume's famous discussion of miracles in the Enquiry Concerning Human Understanding is curious both on account of the arguments he does deploy and on account of the arguments he does not deploy, but might have been expected to. The first and second parts of this paper will be devoted to examining, respectively, these two objects of curiosity. The second part I regard as the more important, because I shall there try to show that the fact that Hume does not deploy (...) an argument that he might have been expected to deploy in fact reflects a weakness in the view of natural laws that has come to be associated with Hume's name. I shall argue, in fact, that it is a symptom of the defectiveness of the ‘Humean’ view of natural laws that on that view it is only too easy to rule out the possibility of a miracle ever occurring. In the third part of the paper, I shall show how another view of laws can overcome this problem. (shrink)

In a famous passage in her book, Intention , Professor G. E. M. Anscombe argues that we can only render intelligible the idea of someone wanting a thing if we know under what aspect the person sees the thing as desirable. The wanted thing must be characterized by the wanter as desirable in some respect. ‘[What] is required for our concept of “wanting”’, she says, ‘is that a man should see what he wants under the aspect of some good’ . (...) And furthermore, ‘the good conceived by the agent to characterize the thing must really be one of the many forms of good’ . Thus, while the object of desire need only be conceived as good by the wanter, and need not be really good, this can only be because the object does not have the desirable character the wanter believes it to have, not because the character supposed to be desirable is not really so. Desire cannot but be for one of the real forms of good. (shrink)

In The City of God , XI, 10, St Augustine claims that the divine nature is simple because ‘it is what it has’ . We may take this as a slogan for the Doctrine of Divine Simplicity , a doctrine which finds its way into orthodox medieval Christian theological speculation. Like the doctrine of God's timeless eternality, the DDS has seemed obvious and pious to many, and incoherent, misguided, and repugnant to others. Unlike the doctrine of God's timeless eternality, the (...) DDS has received very little critical attention. The DDS did not originate with Augustine, but I am not primarily concerned with its pedigree. Nor am I concerned to ask how the doctrine interacts with trinitarian speculation. I will have my hands full as it is. In Section I of this paper I shall provide a rough characterization of the DDS, indicate its complexity, and focus on a particular aspect of the doctrine which will exercise us in the remainder of the paper, namely, the thesis that the divine attributes are all identical with each other and with God. In section n I shall discuss Alvin Plantinga's recent objections to Aquinas' version of the DDS. I shall then offer a more detailed presentation of what I take to be Aquinas' version , and recast it in terms of a theory of attributes which is significantly different from Plantinga's . Although the recasting of the doctrine will enable me to rebut Plantinga's objections , it by no means solves all the problems of the DDS. In section vi I shall discuss the chief lingering problem facing a defender of the DDS. (shrink)

É bem conhecida a oposição estabelecida por Kant entre experiência possível e dialética, na medida em que esta última é caracterizada como a “lógica da ilusão”. Ao mesmo tempo, o modo de pensar metafísico, que ocorre dialeticamente, em sentido kantiano, é uma tendência inevitável da razão, expressa na exigência formal de completude das categorias. Como o pensar, enquanto exercício livre da razão, é em si mesmo mais amplo do que a atividade de conhecer, própria do entendimento, o pensar contém o (...) conhecimento, embora este se qualifique pelas regras e pelos limites determinantes da objetividade. A pergunta que tentaremos formular é se essa relação continente-conteúdo não poderia configurar também uma dependência da experiência em relação ao raciocínio dialético, que estaria de algum modo indicada na função reguladora das idéias da razão. Nesse caso, a oposição formal entre conhecer e pensar seria inseparável da inclusão estrutural (dependência) da experiência no âmbito da razão. Na raiz do problema estaria talvez a tensão (dialética) entre a aspiração subjetiva de totalidade e as exigências objetivas de limitação e segmentação da experiência e a forma da experiência teria de ser finalmente concebida a partir de um fundo de inteligibilidade problemática. Dialectics and experienceThe separation of possible experience as objective knowledge and dialetics as a non-objective or non-theoretical knowledge is one of the most important aspects of kantian critical philosophy. But Kant also says that the activity of reason, as a pure thinking, has more amplitude than understanding knowledge. So we could say that theoric knowledge would depend on rational ( and non-theoretical) knowledge, as something contained in it. If we accept that, the consequence would be a relation of dependence between the form of objective knowledge and the background of a problematic – even doubtful – inteligible knowledge. (shrink)
