The Knowledge Argument

Semantic gaps between physical and mental discourse include the 'explanatory', 'epistemic' (Black-and-White Mary), and 'suppositional' (zombies) gaps; protosemantics is concerned with what is fundamental to meaning. Our tradition presupposes a truth-based protosemantics, with disastrous consequences for interpreting the semantic gaps: nonphysicalism, epiphenomenalism, separatism. Fortunately, an endorsement-based protosemantics, recentering meaning from the world to the mind, is technically viable, intuitively more plausible, and empirically more adequate. But, of present significance, it makes room for interpreting mental discourse as expressing simulations: this blocks (...) the disastrous consequences; and, as a bonus, accommodates hitherto anomalous asymmetries among the various semantic gaps.

I argue that the physiological, phenomenal and conceptual constitute a trichotomous hierarchy of emergent categories. I claim that each category employs a distinctive type of interactive mechanism that facilitates a meaningful kind of environmental discourse. I advocate, therefore, that each have a causal relation with the environment but that their specific class of mechanism qualifies distinctively the meaningfulness of that interaction and subsequent responses. Consequently, I argue that the causal chain of physical interaction feeds distinctive value-laden constructions that are ontologically (...) distinct for each category. Within the limitations of the interactive mechanisms of each category, increasingly sophisticated forms tend to evolve. The increase in sophistication in each category inevitably leads to the emergence of the novel mechanism particular to the next in the hierarchy. In essence, there is an emergent hierarchy of evolving categories delineated by the nature of their mechanism of environmental engagement. I argue that biochemical mechanisms have a tendency to evolve meaningfully, specifically in a way that is both qualitatively relevant and responsive to environmental particulars. I explain that these mechanisms set in play an organisational imperative that leads to the emergence of the capacity to evaluate and prioritise qualitative biochemical assimilations which, inevitably, generates a subjectively individuated experience phenomenon. I then relate this to the novel characteristics of the human perspective. (shrink)

The paper deals with the main argument against the doctrine of Materialism and the heart of the mind-body problem — the Zombie argument. The main proponent of the idea of philosophical zombies is the Australian philosopher David Chalmers, whose main opus 'The Conscious Mind' is wholly based on the idea of conceivability and logical possibility of zombies. The author aims to show that for the adequate analysis of Chalmers' zombie argument, the frame of the Analytic philosophy alone is not sufficient, (...) and due to that, one needs to involve Rene Descartes' philosophy as well as Husserlian phenomenology. It is because the author considers Chalmers' zombie argument as an inverted Cartesian argument from mind-body distinction and which has two levels of argumentation: intuitive obviousness and logical (conceivability-possibility frame). Chalmers' appeal to phenomenal consciousness, experience and intuition gives a solid basis to call his Philosophy of Mind project and himself as analytic phenomenology, and analytic phenomenologist respectively. Key words: the zombie argument, epiphenomenalism, the knowledge argument, intuitive obviousness, analytic phenomenology, continental phenomenology, Chalmers, Descartes, Husserl. (shrink)

In this thesis I examine the view—known as intellectualism—that knowledge-how is a kind of knowledge-that, or propositional knowledge. I examine issues concerning both the status of this view of knowledge-how and the philosophical implications if it is true. The ability hypothesis is an important position in the philosophy of mind that appeals to Gilbert Ryle’s famous idea that there is a fundamental distinction between knowledge-how and knowledge-that. This position appears to be inconsistent with the truth of intellectualism. However, I demonstrate (...) in this thesis that the ability hypothesis can be restated using the intellectualist view of knowledge-how. With regards to the status of intellectualism, I argue that the two main traditional arguments against intellectualism do not succeed. I also provide new and, I claim, successful arguments against intellectualism. These arguments point to a new view of knowledge-how that is distinct from both the standard intellectualist and Rylean views of knowledge-how. (shrink)

I propose an anti-physicalist argument, namely, the imagination argument, and defend it against possible objections. My argument is inspired by Frank Jackson’s knowledge argument, or rather its misinterpretation by Daniel Dennett and Paul Churchland. They interpret the knowledge argument to be about the ability to imagine an unexperienced phenomenal state, which Jackson explicitly denies. The imagination argument, in its rudimentary form, can be briefly put as the following. Let Q be a visual phenomenal quality that is imaginable based on one’s (...) phenomenal experience. (1) It is not possible to (accurately) imagine Q solely based on complete physical knowledge. (2) If it is not possible to (accurately) imagine Q solely based on complete physical knowledge, then physicalism is false. (3) Therefore, physicalism is false. Even though objections have been raised to this argument in the literature, there is, as far as I know, no explicit defense of it. In this paper, I undertake this task and argue that the imagination argument is more plausible than the knowledge argument in some respects, especially because none of the standard objections to the knowledge argument apply to the imagination argument, and less plausible in others, and, all things considered, it is at least as interesting and serious a challenge to physicalism as the knowledge argument is.

An important theme running through D.H. Mellor’s work is his realism, or as I shall call it, his objectivism: the idea that reality as such is how it is, regardless of the way we represent it, and that philosophical error often arises from confusing aspects of our subjective representation of the world with aspects of the world itself. Thus central to Mellor’s work on time has been the claim that the temporal A-series (previously called ‘tense’) is unreal while the B-series (...) (the series of ‘dates’) is real. The A-series is something which is a product of our representation of the world, but not a feature of reality itself. And in other, less central, areas of his work, this kind of theme has been repeated: ‘Objective decision making’ (1980) argues that the right way to understand decision theory is as a theory of what is the objectively correct decision, the one that will actually as a matter of fact achieve your intended goal, rather than the one that is justified purely in terms of what you believe, regardless of whether the belief is true or false. ‘I and now’ (1989) argues against a substantial subjective conception of the self, using analogies between subjective and objective ways of thinking about time and subjective and objective ways of thinking about the self. And in the paper which shall be the focus of my attention here, ‘Nothing like experience’ (1992), Mellor contests arguments which try and derive anti-physicalist conclusions from reflections on the subjective character of experience. A common injunction is detectable: when doing metaphysics, keep the subjective where it belongs: inside the subject’s representation of the world. (shrink)

A primary goal of this chapter is to highlight neglected epistemic parallels between dualism and physicalism. Both dualist and physicalist arguments employ a combination of empirical data and armchair reflection; both rely on considerations stemming from how we conceptualize certain phenomena; and both aim to establish views that are compatible with scientific results but go well beyond the deliverances of empirical science. -/- I begin the chapter by fleshing out the distinctive commitments of dualism, in a way that illuminates the (...) interplay of epistemic and metaphysical elements within the dualist position. Section 2 outlines two influential arguments for dualism and explains how dualists defend those arguments from key criticisms. Sections 3 and 4 examine the most powerful objections to dualism: that it is inferior to physicalism as regards the theoretical virtue of simplicity, and that it cannot explain mental causation. I show that each of these objections to dualism depends on substantial assumptions that cannot be empirically justified. And the objection from mental causation rests on an ambitious assumption about how we conceptualize physical phenomena. Section 5 briefly reviews how epistemic considerations inform arguments on both sides of this debate. (shrink)

According to the Ability Hypothesis, knowing what it is like to have experience E is just having the ability to imagine or recognize or remember having experience E. I examine various versions of the Ability Hypothesis and point out that they all face serious objections. Then I propose a new version that is not vulnerable to these objections: knowing what it is like to experience E is having the ability todiscriminate imagining or having experience E from imagining or having any (...) other experience. I argue that if we replace the ability to imagine or recognize with the ability to discriminate, the Ability Hypothesis can be salvaged. (shrink)

We defend Laurence Nemirow’s and David Lewis’s Ability Hypothesis against Paul Raymont’s criticisms in defense of Jackson’s Knowledge Argument. According to the Ability Hypothesis, what Mary lacked when she was in her black-and-white room was a set of abilities; she did not know how to recognize or imagine certain types of experience. Her subsequent discovery of what it is like to experience color amounts to no more than her acquiring these abilities. Appealing to the Molyneux test, Raymont has argued that (...) knowledge of what an experience is like cannot be equated with the possession of any set of abilities, since one can be in possession of a recognitional ability concerning a certain type of experience without knowing what that experience is like. We argue that the intermodal recognitional ability in the Molyneux test and similar ones depends on previous experience and thus makes an implicit appeal to knowledge of what it is like. (shrink)

This dissertation contains four independent essays addressing a cluster of related topics in the philosophy of mind. Chapter 1: “Fundamentality Physicalism” argues that physicalism can usefully be conceived of as a thesis about fundamentality. The chapter explores a variety of other potential formulations of physicalism (particularly modal formulations), contrasts fundamentality physicalism with these theses, and offers reasons to prefer fundamentality physicalism over these rivals. Chapter 2:“Modal Rationalism and the Demonstrative Reply to the Master Argument Against Physicalism” introduces the Master Argument (...) Against Physicalism and investigates its crucial premise: the inference from an a priori gap between the physical and consciousness to a lack of necessitation between the two. I argue against the strong form of modal rationalism that underwrites the master argument and offer a more moderate rationalist view. I offer a novel demonstrative reply to the master argument, according to which a connection between conscious experience and demonstratives, not dualism, is the source of the epistemic gap between consciousness and the physical. Chapter 3: “Conceptual Mastery and the Knowledge Argument” argues that Frank Jackson’s famous anti-physicalist knowledge argument featuring Mary, a brilliant neuroscientist raised in a black and white room, founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been removed, Mary can know the relevant truths. Chapter 4: “Toward a Theory of Conceptual Mastery” investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I argue against three views of conceptual mastery, according to which conceptual mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. I propose and respond to objections to my own “meaning postulate view” of the conditions under which a thinker has mastery of a concept. (shrink)

This work advances a theory in the metaphysics of phenomenal consciousness, which the author labels “e-physicalism”. Firstly, he endorses a realist stance towards consciousness and physicalist metaphysics. Secondly, he criticises Strong AI and functionalist views, and claims that consciousness has an internal character. Thirdly, he discusses HOT theories, the unity of consciousness, and holds that the “explanatory gap” is not ontological but epistemological. Fourthly, he argues that consciousness is not a supervenient but an emergent property, not reducible and endowed with (...) original causal powers, with respect to the micro-constituents of the conscious entity. Fifthly, he addresses the “zombie argument” and the “supervenience argument” within the e-physicalism framework. Finally, he elaborates on the claim that phenomenal properties are physical and discusses the “knowledge argument”. (shrink)

Few these days dispute that the knowledge argument demonstrates an epistemic gap between the physical facts and the facts about experience. It is much more contentious whether that epistemic gap can be used to demonstrate a metaphysical gap of a kind that is inconsistent with physicalism. In this paper I will explore two attempts to block the inference from an epistemic gap to a metaphysical gap – the first from the phenomenal concept strategy, the second from Russellian monism – and (...) suggest how the proponent of the knowledge argument might respond to each of these challenges. In doing so, I will draw on recent discussions of grounding and essence in the metaphysics literature. (shrink)

This article assesses the reputation of Mary Somerville in the 1830s and suggests that critical confusion over her status in the changing world of early nineteenth-century science is not new. Drawing on Somerville’s own writings, contemporary newspaper and periodical reviews, political debates and unpublished manuscripts, Somerville's ‘uniqueness’ as a public figure is examined through the eyes of both the nascent scientific community of the time as well as the wider audience for her work. Somerville's status as a popularizer and an (...) educator is more complicated than may have previously been assumed and can be both confirmed and undermined by an analysis of contemporary public opinion. Although her works were directed at the public who indirectly paid her pension for services to science, Somerville's private and published comments about and within her writings offer an alternative interpretation. Despite an apparent turn to more popular works in order to bolster her finances, Mary Somerville relished the specialist aspect of her writings and valued the difficulties which prevented the ordinary reader from obtaining ultimate insight into celestial mechanics.

The encounter of the cognitive apparatus with the phenomenal world had led to the emergence of independent thought processes either based on scientific method of enguiry or on meditative experiences. In the course of time these have developed into a systematized body of knowledge. They purport to provide peace and happiness, but when seduced by power a distorted value structure has been legitimized. The plethora of evidences suggest the 'self' has been incapacitated for long. The scientific experiences have been given (...) supreme status. The paper stresses the need to attain a beginner's mind so that looking within and looking without no longer remain intangible goals of education. The naodalities have been discussed to escape the bonds of conceptual limitations. Finally, it is suggested that this constructive role of optimizing the oppor tunities for formation of intellect, which moves beyond conventional intellectualism, will evolve into a com passionate world-serving intellect, and pave the way for peace and harmony in this turbulent world.
