The approach to the question of philosophical practice has been dominated by a subordination of practice to theory corresponding in general to a representational conception of philosophy. Methods of diagrammatic reasoning developed within philosophical semiotics provide a more effective approach. Inparticular, Peirce’s system of existential graphs exemplifies how diagrammatic reasoning is able formally to express the processes through which philosophical dialogue and cooperation actually take place and to link such processes to the methods and practices arising in other disciplines and (...) traditions, including those of science, politics, art, religion and technological production.

(A chapter in a book edited by Rocco Gangle and Julius Greve, titled Superpositions: Laruelle and the Humanities) The human-in-human is nonhuman or “inhuman” (Haraway), monstrous along with the animal, the machine and the darkness of the out-there insofar as it remains a radical hybridity or one that is philosophically unmediated. The real precedes signification and occupies the position of mere materiality (either physicality or machinic materiality) unilaterally situated vis-à-vis a signifying agency. This dual unilaterality is placed within (...) a dyadic structure. The human radical constructedness grounded in—although not reducible to—the binary of technology and the organic (or “nature”) does not make it more rational, more “intelligent,” and less physical, less animal. Quite to the contrary, the kernel of hybridity does not contain a purely technological purpose and is not reducible to the philosophical fetish of rationalism —it is as unruly, as meaningless, as “merely material” as the animal.

This article connects François Laruelle's non-philosophical experiments with the axiomatic method to non-philosophy's anti-hermeneutic stance. Focusing on two texts from 1987 composed using the axiomatic method, "The Truth According to Hermes" and "Theorems on the Good News," I demonstrate how non-philosophy utilizes structural mechanisms to both expand and contract the field of potential models allowed by non-philosophy. This demonstration involves developing a notion of interpretation, which synthesizes Rocco Gangle's work on model theory with respect to non-philosophy with Laruelle's (...) critique of hermeneutics. I use Alexander Galloway's interpretation of "The Truth According to Hermes" as a case study of the limits non-philosophy sets upon its use as a basis for philosophical models, in contrast to arguments by Gangle regarding non-philosophy's greater genericity in comparison to philosophy.

Heiko Puls’ work Sittliches Bewusstsein und Kategorischer Imperativ in Kants Grundlegung: Ein Kommentar zum dritten Abschnitt, presents an attempt to show that, in the Groundwork of the Metaphysics of Morals, Kant’s argumentation for the objective value of the categorical imperative is almost based upon the same principle as the one presented in the second Critique. More precisely, Puls claims that, like in the Critique of Practical Reason, the Groundwork operates with some kind of fact of reason-theory, which means that our (...) consciousness of the moral law is the ratio cognoscendi of our freedom of will. Accordingly, there is no conclusion from a kind of non-moral consciousness of freedom to the freedom of will and from here to the objective value of the categorical imperative, as many interpreters assume. Due to the ambitiousness of his main thesis and his detailed and subtle way of arguing, Puls’ work represents an important and innovative contribution to recent research on Kant’s Groundwork. Nevertheless, his interpretations sometimes seem to favour analysis of loose philological relationships over closer looks on the contexts of passages. Or he focuses excessively on isolated textual evidences for his readings without appropriately recognising the various other evidences against it. In what follows, I give examples for this criticism.

“If you find it strange that, in setting out these elements, I do not use those qualities called heat, cold, moistness, and dryness, as do the philosophers, I shall say to you that these qualities appear to me to be themselves in need of explanation. Indeed, unless I am mistaken, not only these four qualities, but also all the others (indeed all the forms of inanimate bodies) can be explained without the need of supposing for that purpose any other thing (...) in their matter than the motion, size, shape, and arrangement of its parts.” So does Descartes, in his The World, or Treatise on Light [Le Monde ou Traité de la Lumière], express the uniphenomenal principle of the physical world, which is the basis - or foundation - of his great cosmic synthesis. The uniphenomenal character of Cartesian physics - namely, explaining all phenomena and appearances from a single primordial phenomenon (and substance) - has such a great semantic and intuitive value for the structure of the human mind that Plato, even before Aristotle’s hyle, had come to contemplate his concept of chora, the cosmic and universal matrix at the base of all phenomena, existing before and beyond the coming into existence of the elements and of sensible things. Even the physics of Democritus is uniphenomenal. A perfect example of uniphenomenal physics in our time is the Spacio-fluido-dynamics of the scientist Marco Todeschini (Bergamo, 1899 - 1988) who, with his monumental Teoria delle apparenze [Theory of Appearances] of ’49 tried to clear a path towards the hope of reaching a Cartesian kind of unified cosmic synthesis. (We accept only the fundamental concept of Todeschi’s theory here, that is, the uniphenomenal character of his physics, without occupying ourselves with criteria such as the value or the plausibility of his hypotheses.) This concept of uniphenomenal physics will serve as an ultra-clear instrument to dissipate the epistemological fog of AI (Artificial Intelligence). (shrink)

The philosophy by Husserl has always been a very interesting topic for cognitive scientists. Indeed, there is a strong analogy between the method of phenomenological reduction and the theories of mind developed by cognitive science in the last fifty years. The method of reduction is based on the concept of reality as a product of mind. Cognitive science seems to agree with this view but it is still difficult to elaborate a cognitive interpretation of the Husserl phenomenology which is philosophically (...) correct. The best attempt is that by Francisco Varela; thanks to the philosophic teaching of Humberto Maturana, he offers us a terribly reliable and audacious interpretation of Husserl even if complex for the role which plays between two necessities: the former is to construct neurophenomenology emphasizing the philosophy of Husserl like the only conceptual architecture able to study experience directly and the latter (which) is to found the enactive paradigm for cognitive science referring to Buddhist psychology.

Jean-Paul Sartre believed that consciousness entails self-consciousness, or, even more strongly, that consciousness is self-consciousness. As Kathleen Wider puts it in her terrific book The Bodily Nature of Consciousness: Sartre and Contemporary Philosophy of Mind, ‘all consciousness is, by its very nature, self-consciousness.’ I share this view with Sartre and have elsewhere argued for it at length. My overall aim in this paper is to examine Sartre's theory of consciousness against the background of the so-called ‘higher-order thought theory of consciousness’ (...) which, in turn, will shed light on the structure of conscious mental states as well as on Sartre's theory of consciousness and reflection. Another goal of this paper is, following Wider, to show how Sartre's views can be understood from a contemporary analytic perspective. Sartre's theory of consciousness is often confusing to the so-called ‘analytic Anglo-American’ tradition, but I attempt to show how this obstacle can be overcome against the backdrop of a specific contemporary theory of consciousness.

Various psychopathologies of self-awareness, such as somatoparaphrenia and thought insertion in schizophrenia, might seem to threaten the viability of the higher-order thought (HOT) theory of consciousness since it requires a HOT about one’s own mental state to accompany every conscious state. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that there is a HOT to the effect that “I am in mental state M.” I have argued in previous work that a (...) HOT theorist can adequately respond to this concern with respect to somatoparaphrenia and thought insertion. There is also Cotard syndrome which is a rare neuropsychiatric disorder in which people hold the delusional belief that they are dead, do not exist, or have lost their blood or internal organs. In this paper, I argue that HOT theory has nothing to fear from it either and can consistently account for what happens in such unusual cases. I analyze Cotard syndrome in light of my previous discussion of somatoparaphrenia and thought insertion, and argue that HOT theory can provide a somewhat analogous account without the worry of inconsistency. It is crucial to recognize that there are multiple “self-concepts” and levels of HOTs which can help to provide a more nuanced explanation. With regard to the connection between consciousness and self-consciousness, it is proposed that Cotard patients are indeed capable of having some “I-thoughts” about their bodies and mental states.

Misrepresentation, empty HOTs, and intrinsic HOTs: A reply to Pereplyotchik.

It is often said that some kind of peripheral (or inattentional) conscious awareness accompanies our focal (attentional) consciousness. I agree that this is often the case, but clarity is needed on several fronts. In this paper, I lay out four distinct theses on peripheral awareness and show that three of them are true. However, I then argue that a fourth thesis, commonly associated with the so-called "self-representational approach to consciousness," is false. The claim here is that we have outer focal (...) consciousness accompanied often (or even always) by inner peripheral (self-)awareness. My criticisms stem from both methodological and phenomenological considerations. In doing so, I offer a diagnosis as to why the fourth thesis has seemed true to so many and also show how the so-called "transparency of experience," frequently invoked by representationalists, is importantly relevant to my diagnosis. Finally, I respond to several objections and to further attempts to show that thesis four is true. What emerges is that if one wishes to hold that some form of self-awareness accompanies all outer-directed conscious states, one is better off holding that such self-awareness is itself unconscious, as is held for example by standard higher-order theories of consciousness.

Various psychopathologies of self-awareness, such as somatoparaphrenia and thought insertion in schizophrenia, might seem to threaten the viability of the higher-order thought (HOT) theory of consciousness since it requires a HOT about one’s own mental state to accompany every conscious state. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that there is a HOT to the effect that “I am in mental state M” (Rosenthal 2005, Gennaro 2012). In a previous publication (...) (Gennaro 2015), I argued that a HOT theorist can adequately respond to this concern with respect to somatoparaphrenia. Somatoparaphrenia is a “depersonalization disorder” which is characterized by the sense of alienation from parts of one’s body. It is a bizarre type of body delusion where one denies ownership of a limb or an entire side of one’s body. My focus in the chapter, however, is on “inserted thoughts” which is a common symptom of schizophrenia, although it will also be useful to contrast it with somatoparaphrenia. Schizophrenia is a mental disorder which most commonly manifests itself through auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking. Thought insertion is the delusion that some thoughts are not “one’s own” in some sense or are somehow being inserted into one’s mind by someone else. Graham and Stephens (2000), for example, have suggested that thought insertion should be understood as alienated self-consciousness or meta-representation. I argue that HOT theory has nothing to fear from this phenomenon either and can consistently explain what happens in this admittedly unusual case. (shrink)

It has long been known that brain damage has important negative effects on one’s mental life and even eliminates one’s ability to have certain conscious experiences. It thus stands to reason that when all of one’s brain activity ceases upon death, consciousness is no longer possible and so neither is an afterlife. It seems clear that human consciousness is dependent upon functioning brains. This essay reviews some of the overall neurological evidence from brain damage studies and concludes that our argument (...) from brain damage has been vindicated by such overwhelming evidence. It also puts forth a more mature philosophical rationale against an afterlife and counters several replies to the argument. -/- 1. Philosophical Background -- 2.

The higher-order thought (HOT) theory of consciousness is a reductive representational theory of consciousness which says that what makes a mental state conscious is that there is a suitable HOT directed at that mental state. Although it seems that any neural realization of the theory must be somewhat widely distributed in the brain, it remains unclear just how widely distributed it needs to be. In section I, I provide some background and define some key terms. In section II, I argue (...) against the view that HOT theory should treat first-order (i.e. world-directed) conscious states as requiring prefrontal cortical activity though it is reasonable to suppose that conscious states are realized in the brain. In section III, I then explore some of the key background metaphysical issues involved in understanding the nature of consciousness, such as the debate between realism and idealism as well as the prospects for solving the so-called “hard problem” of consciousness. Some of the differences in question often mirror the traditional differences between Western and Eastern perspectives on the nature of consciousness. Overall, I argue that some form of realism and physicalism is more plausible than the opposing views. I also argue that materialists (and especially HOT theorists) can offer plausible replies to the hard problem. (shrink)

Somatoparaphrenia is a pathology of self characterized by the sense of alienaton from parts of one’s body. It is usually construed as a kind of delusional disorder caused by extensive right hemisphere lesions. Lesions in the temporoparietal junction are common in somatoparaphrenia but deep cortical regions (for example, the posterior insula) and subcortical regions (for example, the basal ganglia) are also sometimes implicated (Valler and Ronschi 2009). Patients are often described as feeling that a limb belongs to another person and (...) thus attribute ownership of the limb and bodily sensation to someone else. There is also some question as to whether or not the higher-order thought (HOT) theory of consciousness can plausibly account for the depersonalization psychopathology of somatoparaphrenia (Liang and Lane 2009, Rosenthal 2010, Lane and Liang 2010). Liang and Lane argue that it cannot. The HOT theory of consciousness says that what makes a mental state a conscious mental state is that it is the target of a HOT to the effect that “I am in mental state M” (Rosenthal 2005, Gennaro 2012). When the HOT is itself is unconscious, the conscious state is still outer-directed. When the HOT is conscious, we have introspection and so the conscious thought is directed at the mental state. In section I, I briefly review the previous exchange between Lane and Liang and David Rosenthal. In section II, I further explore somatoparaphrenia and the nature of delusion while offering a number of additional replies to Lane and Liang. In section III, I examine the central notions of “mental state ownership” and “self-concepts” in an effort to account especially for the depersonalization aspect of somatoparaphrenia against the background of HOT theory. In section IV, I argue that to the extent that somatoparaphrenia casts doubt on the notion that some thoughts are “immune to error through misidentification” (IEM), the most fundamental aspect of IEM is still consistent with HOT theory. Overall, I argue that HOT theory is left unscathed by the pheneomenon of somatoparaphrenia and can even help to explain what happens in these cases. (shrink)

I first provide some background on Sartre’s theory of consciousness and prereflective self-awareness, especially with respect to how it might be favorably compared to my own version of HOT theory. I then critically examine a few initial attempts to understand the ‘acquaintance’ relation and to link it with Sartre’s notion of prereflective self-awareness. I then briefly address a related problem often raised against HOT theory, namely, the problem of misrepresentation. I also critique several further attempts to explain the acquaintance relation (...) and argue that they are inadequate. I then critically evaluate Hellie’s (2007) argument favoring acquaintance theory over higher-order theories. I then argue that the move to “adverbialism” fails to save acquaintance theory and should also be rejected on other grounds. Overall, I argue that many of the properties association with prereflective non-positional consciousness or self-awareness can be best accommodated by a version of HOT theory. (shrink)

Synesthesia is the “union of the senses” whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together in experience. For example, some synesthetes experience a color when they hear a sound or see a letter. In this paper, I examine two cases of synesthesia in light of the notions of “experiential parts” and “conscious unity.” I first provide some background on the unity of consciousness and the question of experiential parts. I (...) then describe two very different cases of synesthesia. Finally, I critically examine the cases in light of two central notions of “unity.” I argue that there is good reason to think that the neural “vehicles” of conscious states are distributed widely and can include multiple modalities. I also argue that some synesthetic experiences do not really enjoy the same “object unity” associated with normal vision. (shrink)

Synesthesia literally means a “union of the senses” whereby two or more of the five senses that are normally experienced separately are involuntarily and automatically joined together in experience. For example, some synesthetes experience a color when they hear a sound, although many instances of synesthesia also occur entirely within the visual sense. In this paper, I first mainly engage critically with Sollberger’s view that there is reason to think that at least some synesthetic experiences can be viewed as truly (...) veridical perceptions, and not as illusions or hallucinations. Among other things, I explore the possibility that many forms of synesthesia can be understood as experiencing what I will call “second-order secondary properties,” that is, experiences of properties of objects induced by the secondary qualities of those objects. In doing so, I shed some light on why synesthesia is typically one-directional and its relation to some psychopathologies such as autism. (shrink)

In response to Fred Adams and Charlotte Shreve’s (2016) paper entitled “What Can Synesthesia Teach Us about Higher Order Theories of Consciousness?”, previously published in Symposion, I argue that H.O.T. theory does have the resources to account for synesthesia and the specific worries that they advance in their paper, such as the relationship between concepts and experience and the ability to handle instances of ‘pop-out’ experiences.

This chapter addresses the extent to which nonhuman animals are conscious. Most important perhaps is what criteria should be used in making such a determination.

This essay explores the topic of Dissociative Identity Disorder (formerly called “Multiple Personality Disorder”) with special attention to such Quadrophenia masterpieces as “Dr. Jimmy” and “The Real Me.” A number of major philosophical questions arise: Can two or more “persons” really inhabit the same body? How can we hold Dr. Jimmy morally responsible for the reprehensible actions of Mr. Jim? Wouldn’t it be wrong to do so if they are really different people? What is it to be the “same” person (...) over time? Does Dr. Jimmy really have free will? The focus is on the much discussed and important notions of personal identity, free will, and moral responsibility. (shrink)

For patients under anesthesia, it is extremely important to be able to ascertain from a scientific, third person point of view to what extent consciousness is correlated with specific areas of brain activity. Errors in accurately determining when a patient is having conscious states, such as conscious perceptions or pains, can have catastrophic results. Here, I argue that the effects of (at least some kinds of) anesthesia lend support to the notion that neither basic sensory areas nor the prefrontal cortex (...) (PFC) is sufficient to produce conscious states. I also argue that it this is consistent with and supportive of the higher-order thought (HOT) theory of consciousness. I therefore disagree in some ways with Mehta and Mashour (2013), who argue that evidence from anesthesia mainly favors a first-order representational (FOR) theory, as opposed to HOT theory (and many other theories, for that matter).

This is my reply to Josh Weisberg, Robert Van Gulick, and William Seager, published in JCS vol 20, 2013. This symposium grew out of an author-meets-critics session at the Central APA conference in 2013 on my 2012 book THE CONSCIOUSNESS PARADOX (MIT Press). Topics covered include higher-order thought (HOT) theory, my own "wide intrinsicality view," the problem of misrepresentation, targetless HOTs, conceptualism, introspection, and the transitivity principle.

In Gennaro (2016), I had originally replied to Fred Adams and Charlotte Shreve’s (2016) paper entitled “What Can Synesthesia Teach Us About Higher Order Theories of Consciousness?,” previously published in Symposion. I argued that H.O.T. theory does have the resources to account for synesthesia and the specific worries that they advance in their paper, such as the relationship between concepts and experience and the ability to handle instances of ‘pop-out’ experiences. They counter-reply in Adams and Shreve (2017) and also raise (...) further objections to H.O.T. theory which go well beyond the scope of their 2016 paper. In this paper, I offer additional replies to the points they raise in Adams and Shreve (2017). (shrink)

In this text I analyze the relationship between historiography, politics, and wider historical culture. Starting point for my argumentation are the organization “Historians without Borders” and a contentious resolution by the “Association of German Historians” from 2018. In a first step, I shortly reconstruct the relationship between politics, historical culture, and historiography that is presupposed by both the organization and the resolution. Next, I argue that historiography has a specific and unique role to play in historical culture and democracy as (...) producer of historical knowledge and understanding and that there are legitimate political interests that directly stem from those activities. In particular, based on their professional activities historians have good grounds to stand in for the establishment or maintenance of deliberative democratic systems with which their professional endeavour shares many principles and commonalities.

Discussione sul testo di Rocco Ronchi "Gilles Deleuze. Credere nel reale". Per un pensiero della temporalità della filosofia come Fuori assoluto.

Rosenthal descreve a consciência de criatura como o simples fato de uma criatura estar desperta e atenta aos estímulos externos da natureza. Estas criaturas conscientes possuem determinados estados mentais que representam os fenômenos da natureza, isto é, uma certa propriedade mental que estabelece uma relação entre o fenômeno da natureza, e aquilo que percebemos desse fenômeno. Estes estados mentais podem ou não estarem presentes na consciência de criatura. O que é responsável por tornar esses estados mentais conscientes? Para tentar responder (...) a essa pergunta, Rosenthal propõe uma teoria baseada em estados mentais de ordem superior. Estes estados mentais, não representam fenômenos externos, mas outros estados mentais,tornando estes últimos em estados mentais conscientes. Entretanto, Charles Siewert (1996) afirma que Rosenthal comete o mesmo erro de Brentano ao responder esse problema da consciência com o uso de estados mentais de ordem superior. Porém, não é verdade que Brentano se utiliza da ordem superior para elaborar sua teoria sobre a consciência, Brentano (1874) utiliza estados mentais internos que se autorrepresentam de determinada forma. Outros autores, como Dan Zahavi (2004), Rocco Gennaro (1996) entre outros, também estabelecem uma ligação entre Rosenthal e Brentano, alguns afirmando que suas teorias são equivalentes, outros negando. Devido a essa recorrente confusão, o objetivo do trabalho é não só uma análise das teorias dos dois autores, mas também uma comparação entre os fundamentos, as argumentações e as características de ambas as teorias. Dessa forma, pretendo ao final deste dissertação mostrar que as teorias da consciência de Rosenthal e de Brentano são profundamente diferentes. Além disso, pretendo mostrar com base tanto no funcionamento da teoria, quanto em estudos empíricos, a teoria de Rosenthal parece estar mais adequada para explicar o fenômeno da consciência.

Articolo in occasione del quindicesimo anniversario della morte di Carmelo Bene.

Nel suo "Il canone minore", Rocco Ronchi descrive il tentativo compiuto da quelle figure, sovente eretiche del pensiero rispetto a quello che l’autore individua come canone maggiore, che nel corso della storia della filosofia hanno pensato davvero l'immanenza dell’assoluto o, che è lo stesso, l’univocità dell’essere sul piano degli enti di natura. Nell’esigenza fondamentalmente speculativa e per ciò stesso anti-moderna della filosofia, ciò che si dà a vedere quale dato immediato dell’intuizione è un'equivalenza solo apparentemente innocua, ma in realtà (...) profondamente perturbante e traumatica: immanenza assoluta = natura.
