Traditionally, introspection has been considered as the privileged and most secure way of acquiring knowledge. However, this traditional view has met various strands of criticism over the centuries. It has been argued not only that introspection is not epistemically privileged, but also that it is even less reliable than other methods of acquiring knowledge (such as perception, memory, and inference), and perhaps not reliable at all. Some philosophers have even denied the very existence of introspection, and argued that, in fact, introspection is impossible. This chapter reviews a selection of the most prominent skeptical arguments against introspection and proposes some ways to address them. Introspection may not be as epistemically outstanding as some Cartesians might have thought, but it is also not as epistemically despicable as its critics have suggested.

Maja Spener’s Introspection: First-Person Access in Science and Agency (Spener 2024) is an invaluable contribution to the debate about the nature and reliability of introspection. By sifting it through a novel, illuminating, and very much needed conceptual framework, the book lays the foundation for that debate to substantially move forward. The book’s main aim is to offer a detailed diagnosis of introspection’s epistemological shortcomings, provide the tools for a careful analysis of its limitations and methodological potential, and open up moderately optimistic prospects with respect to its use in science.

Maja Spener develops a greatly useful conceptual framework aimed at dissolving widespread ambiguities that have affected the debate around introspection’s reliability since its incipience. One application of this framework is to address the “problem of self-observation.” Roughly, the problem is that, whenever one tries to “observe” one’s conscious experience by focusing one’s attention on it, the very act of observation alters the experience it is supposed to target. Spener argues that the problem of self-observation is primarily a problem of scientific inquiry, concerning the legitimacy of self-observation as scientific method, and that it should be addressed as such. To complement Spener’s treatment of the problem, however, I think that we also need a detailed analysis of the kind and extent of the experiential effects of self-observation as mode of introspective access—i.e., of inner attention. In this commentary, I offer a preliminary sketch of what seems to me a promising way to move forward in this direction.

One of the most fundamental divides in contemporary philosophy of consciousness is whether phenomenal consciousness requires some form of self-consciousness. More specifically, disagreement revolves around the “Awareness Principle”: For any subject S and conscious mental state M of S, S is aware of M. We call the relevant awareness of one’s own mental states “inner awareness.” While the Awareness Principle (or some idea in the vicinity) was largely accepted by early phenomenologists and early analytic philosophers, it is much more disputed by contemporary philosophers of mind. In this chapter, we offer a bird’s-eye view of philosophical debates surrounding the Awareness Principle. Our goal is to review the main theoretical options available on the market. We open by distinguishing various versions of the Awareness Principle (§1) before addressing the place of inner awareness in the history of philosophy (§2) and in contemporary debates on consciousness (§3).

In recent years, interest in the value of consciousness has gained momentum. Much of the debate has focused on the epistemic and ethical value of consciousness. At least in principle, there is a third kind of value that may be attributed to consciousness: aesthetic value. The question of the aesthetic value of consciousness concerns not (or not just) whether consciousness is a necessary condition for the existence or instantiation of aesthetic value, but whether consciousness itself instantiates some aesthetic value. Research on the aesthetic value of consciousness in this sense has been virtually inexistent until very recently. Due to its embryonic state, almost everything about this potential new research area is yet undefined. In this paper, I attempt a preliminary articulation of some of the questions an aesthetics of consciousness may investigate, suggest a tentative evaluation of possible answers and lines of investigation, and offer some reflections on whether an aesthetics of consciousness is a philosophical enterprise worth pursuing.

Introspection is fundamental and seemingly indispensable to understanding the conscious human mind. It is essential both to acquire and refine our knowledge of ourselves and to develop a philosophical and a scientific investigation of consciousness. It is also a controversial topic, celebrated both as the foundation for knowledge whilst being criticized for being hopelessly unreliable. Despite such disagreement, both the nature and study of introspection remains of prime importance for philosophy, psychology and cognitive science. The Routledge Handbook of Introspection is an outstanding exploration and reference source on introspection. Thirty-seven chapters written by an international team of expert contributors are divided into eight clear parts: Historical and Non-Western Perspectives on Introspection Theories of Introspection The Epistemology of Introspection Introspection and Consciousness Science Introspection, Consciousness, and the Self Introspection and Other Mental Phenomena Introspection, Psychology, and Psychoanalysis The Value of Introspection. Within these sections, important concepts are examined, including the nature of introspection; privileged access; the self and self-knowledge; the metaphysics of consciousness; skepticism; transparency; attention; perception; action; inner speech; emotion and mood; self-deception; and the moral value of introspection. A key strength of the Handbook is it engagement with topics in psychology and cognitive science. As such, The Routledge Handbook of Introspection will be of great interest to students and researchers in philosophy of mind and psychology, as well as in psychology and cognitive science.

The philosophical debate around moods has mainly focused on whether and how their seeming recalcitrance to representationalist treatment can be overcome by accommodating moods’ apparent undirectedness through a peculiar representational structure. Through these theoretical efforts, though, most theorists have taken a double wrong turn (or so I argue), by maintaining that (i) (if directed,) moods are outwardly directed (i.e., directed toward something external to and independent of the subject’s mind) and (ii) moods are discrete mental states (on a par with emotions, perceptual experiences, thoughts, etc.). By pointing at three as yet overlooked phenomenological features of moods—subjective salience, undetachability, and globality—I suggest that moods are (i) inwardly oriented (i.e., they pertain to the subjective aspect of experience and, if directed at all, they are directed toward one’s experiences) and (ii) structural features of consciousness (rather than discrete mental states). I thus explore a new approach to the nature of mood experience, one that aims to do justice to those phenomenological features: I call this the “ways of inner awareness” view. On this view, moods are ways of being aware of one’s own experiences. Different versions of the view may be developed, depending on various metaphysical commitments. I do not defend or recommend, here, any specific version. The aim of the paper is to motivate the general ways-of-inner-awareness approach to mood and hint at some possible ways it may be elaborated.

We present a new argument in favor of the Awareness Principle, the principle that one is always aware of one’s concurrent conscious states. Informally, the argument is this: (1) Your conscious states are such that you can attend to them without undertaking any action _beyond mere shift of attention_; but (2) You cannot come to attend to something without undertaking any action beyond mere shift of attention unless you are already aware of that thing; so, (3) Your conscious states are such that you are aware of them. We open by introducing more fully the Awareness Principle (§ 1) and explicating the crucial notion of “mere shift of attention” (§ 2). We then develop the argument more fully, first in an intuitive form (§ 3) and then more formally (§ 4), before replying to a series of objections (§§ 5–7).

The philosophical debate around the nature of moods has mostly focused on their apparent undirectedness: unlike mental states such as perceptual experiences, thoughts, and emotions, moods do not seem to be directed at any specific object, and indeed they do not seem to be directed at anything at all. In this paper, I want to draw attention to a different feature of moods, one that is as important and in need of explanation as their apparent undirectedness, but which has been overlooked by most participants in the debate: the fact that moods involve a particularly marked salience of the subjective aspect of experience. I argue that any adequate theory of moods should account for this fact. I call this the “subjective salience desideratum.” In the bulk of the paper, I articulate and motivate the desideratum, show that extant theories of moods do not satisfy it, and offer a preliminary overview of possible (yet unexplored) theories that have the subjective salience desideratum at their core.

Conscious intentional states are mental states that represent things as being a certain way and do so consciously: they involve a phenomenally conscious representation. For any phenomenally conscious state, there is something it is like for its subject to be in it. The way it is like for a subject to be in a certain phenomenal state is the state’s phenomenal character. According to some authors, phenomenal character has two components: qualitative character (i.e., the “what it is like” component) and subjective character (the “for the subject” component). Elsewhere, I have argued for an acquaintance theory of subjective character: a conscious representation is “for the subject” iff the subject is acquainted with it (Giustina forthcoming). The aim of this paper is to take some initial steps toward developing an acquaintance account of qualitative character. More specifically, I develop an acquaintance-representational account of the qualitative character of conscious intentional states, on which qualitative character is constituted by a subject’s being acquainted with the conscious intentional state’s representational properties. By reviewing the main extant accounts of qualitative character and highlighting their shortcomings, I argue that the acquaintance-representational account is antecedently more plausible than its competitors.

Most recent philosophical theories of consciousness account for it in terms of representation, the bulk of the debate revolving around whether (suitably) representing something is sufficient for consciousness (as per first-order representationalism) or some further (meta-)representation is needed (as per higher-order representationalism and self-representationalism). In this paper, I explore an alternative theory of consciousness, one that aims to explain consciousness not in terms of representation but in terms of the epistemically and metaphysically direct relation of acquaintance. I call this the Inner Acquaintance Theory of consciousness (IAT). Roughly, on IAT, what makes a mental state conscious is its subject being acquainted with it. Though not wholly unprecedented, IAT is still at the fringe of consciousness debates and remains largely underexplored. The main goal of this paper is to take some steps toward developing the details of IAT, illustrate its potential explanatory power, and put it forward as a plausible alternative to representational theories, with the hope that this will contribute to shifting IAT closer to the center of the debate. Here is how I proceed. In §2 I introduce a notion—inner awareness—that is crucial both to contextualize and to understand IAT. In §3 I provide some preliminary motivation for exploring IAT. In §4 I explain the notion of acquaintance and illustrate some of the features that are typically attributed to it in the literature. The details of IAT are then shaped through four main decision points. I address them in §§5-8, where I suggest a particular choice at each decision point, thereby progressively building up a view that I consider particularly promising.

The primary goal of this paper is to provide substantial motivation for exploring an Acquaintance account of phenomenal consciousness, on which what fundamentally explains phenomenal consciousness is the relation of acquaintance. Its secondary goal is to take a few steps towards such an account. Roughly, my argument proceeds as follows. Motivated by prioritizing naturalization, the debate about the nature of phenomenal consciousness has been almost monopolized by representational theories. Among them, Self-Representationalism is by far the most antecedently promising. However, on thorough inspection, Self-Representationalism turns out not explanatorily or theoretically better than the Acquaintance account. Indeed, the latter seems to be superior in at least some important respects. Therefore, at the very least, there are good reasons to take the Acquaintance account into serious consideration as an alternative to representational theories. The positive contribution of this paper is a sketch of an account of consciousness on which phenomenal consciousness is explained partly in representationalist terms, but where a crucial role is played by the relation of acquaintance.

One of the major divides in contemporary philosophy of consciousness is on whether phenomenal consciousness requires some form of self-consciousness. The disagreement revolves around the following principle (or something in the vicinity): : For any subject S and phenomenally conscious mental state C of S, C is phenomenally conscious only if S is aware of C. We may call the relevant awareness of one’s own mental states “inner awareness” and the principle “Inner Awareness Principle” (IA). In a paper recently published in this Journal, Stoljar (2021) puts forward a massive theoretical criticism of IA. He addresses many extant arguments for IA, and argues, for each of them, that it is unpersuasive. In this paper, I focus on what strike me as the two most compelling arguments in Stoljar’s list: the argument from memory and the argument from attention. I argue that Stoljar’s objections to them can be rebutted; accordingly, those arguments promise to constitute the steadiest theoretical ground for IA.

Introspective knowledge by acquaintance is knowledge we have by being directly aware of our phenomenally conscious states. In this paper, I argue that introspective knowledge by acquaintance is a sui generis kind of knowledge: it is irreducible to any sort of propositional knowledge and is wholly constituted by a relationship of introspective acquaintance. My main argument is that this is the best explanation of some epistemic facts about phenomenal consciousness and introspection. In particular, it best explains the epistemic asymmetry between a subject who has never had a certain phenomenal state and one who has. I also consider two theoretical objections to my claim: an objection from disunity and an objection from mysteriousness. I show that these objections can be answered and that introspective knowledge by acquaintance being sui generis remains a live option on the table.

The psychological reality of an inner awareness built into conscious experience has traditionally been a central element of philosophy of consciousness, from Aristotle, to Descartes, Brentano, the phenomenological tradition, and early and contemporary analytic philosophy. Its existence, however, has recently been called into question, especially by defenders of so-called transparency of experience and first-order representationalists about phenomenal consciousness. In this paper, I put forward a defense of inner awareness based on an argument from memory. Roughly, the idea is that since we can only recall something if we were aware of it at the time of its occurrence, and since we can recall our own experiences, we must be aware of our own experiences at the time of their occurrence. The argument is far from new: it goes back to the Buddhist tradition and has been revived more recently in Buddhist Scholarship but also in contemporary analytic philosophy of mind, in particular by Uriah Kriegel. However, I believe that, since it is the best extant argument for inner awareness, it deserves more extensive treatment. My goal is to strengthen the memory argument by making some conceptual distinctions as to the exact thesis about inner awareness that the argument is supposed to support, considering different ways the argument may be reconstructed depending on the exact thesis to be supported, and defending the argument from a new objection, raised very recently by Daniel Stoljar.

In this paper, we argue that knowledge of emotions essentially depends on introspecting the phenomenology of emotional experiences, and that introspection of emotional experiences is a process by stages, where the most fundamental stage is a non-classificatory introspective state, i.e., one that does not depend on the subject’s classifying the introspected emotion as an instance of any experience type. We call such a non-classificatory kind of introspection primitive introspection. Our main goal is to show that, although not sufficient, primitive introspection is a necessary ground to acquire knowledge of emotions. Our main argument is phenomenological: by examining a variety of examples, we suggest that an accurate analysis of the introspective process through which one comes to know, or refines one’s knowledge of, one’s current emotion requires that one primitively introspects it.

In this paper, I develop a new version of the acquaintance view of the nature of introspection of phenomenal states. On the acquaintance view, when one introspects a current phenomenal state of one's, one bears to it the relation of introspective acquaintance. Extant versions of the acquaintance view neglect what I call the phenomenal modification problem. The problem, articulated by Franz Brentano in his Psychology from an Empirical Standpoint, is that drawing introspective attention to one's current conscious experience may modify its phenomenology. Failing to take phenomenal modification into account affects the adequacy of extant versions of the acquaintance view. The purpose of this paper is to develop a better version, the integration account, that meets the phenomenal modification challenge while preserving the merits of other versions.

One of David Rosenthal’s many important contributions to the philosophy of mind was his clear and unshirking account of introspection. Here we argue that while there is a kind of introspection (we call it “reflective introspection”) that Rosenthal’s account may be structurally fit to accommodate, there is also a second kind (“primitive introspection”) that his account cannot recover. We introduce Rosenthal’s account of introspection in §1, present the case for the psychological reality of primitive introspection in §2, and argue that Rosenthal’s account lacks the resources to accommodate it in §3.

The Brentanian idea that every state of consciousness involves a consciousness or awareness of itself (Brentano 1874), which has been a central tenet of the phenomenological school, is a current topic in contemporary philosophical debates about consciousness and subjectivity, both in the continental and the analytic tradition. Typically, the self-awareness that accompanies every state of consciousness is characterized as pre-reflective. Most theorists of pre-reflective self-awareness seem to converge on a negative characterization: pre-reflective self-awareness is not a kind of reflective awareness. Whereas reflective self-awareness is attentive and descriptive, pre-reflective self-awareness is non-attentive and non-descriptive. This paper aims to show that the reflective/pre-reflective dichotomy overlooks a finer-grained distinction. The first part is devoted to arguing that the typical use of the adjective ‘pre-reflective’ conflates two properties (non-attentiveness and non-descriptiveness), which are in fact separable. Accordingly, not only can there be non-descriptive and non-attentive self-consciousness (i.e. pre-reflective self-awareness), but also non-descriptive but attentive self-consciousness. I call the latter primitive introspection. The second part of the paper is devoted to arguing that, whereas both pre-reflective self-awareness and primitive introspection enable the subject to apprehend the phenomenology of their experience, the kind of apprehension each allows for is different. By analyzing the notion of apprehension in terms of information acquisition and personal-level availability of information, it is proposed that, although both pre-reflective self-awareness and primitive introspection allow for acquisition of the maximal amount of information about the experience, only primitive introspection makes all such information personal-level available.

Phenomenal beliefs are beliefs about the phenomenal properties of one's concurrent conscious states. It is an article of common sense that such beliefs tend to be justified. Philosophers have been less convinced. It is sometimes claimed that phenomenal beliefs are not on the whole justified, on the grounds that they are typically based on introspection and introspection is often unreliable. Here we argue that such reasoning must guard against a potential conflation between two distinct introspective phenomena, which we call fact-introspection and thing -introspection; arguments for the unreliability of introspection typically target only the former, leaving the reliability of the latter untouched. In addition, we propose a theoretical framework for understanding thing -introspection that may have a surprising consequence: thing -introspection is not only reliable, but outright infallible. This points at a potential line of defense of phenomenal-belief justification, which here we only sketch very roughly.

The focus of this paper is introspection of phenomenal states, i.e. the distinctively first-personal method through which one can form beliefs about the phenomenology of one’s current conscious mental states. I argue that two different kinds of phenomenal state introspection should be distinguished: one which involves recognizing and classifying the introspected phenomenal state as an instance of a certain experience type, and another which does not involve such classification. Whereas the former is potentially judgment-like, the latter is not. I call them, respectively, reflective introspection and primitive introspection. The purpose of this paper is to argue that primitive introspection is a psychologically real phenomenon. I first introduce the distinction and provide some preliminary motivation to accept it (§1). After some set-up considerations (§2), I present my central argument for the existence of a non-classificatory kind of introspective state (§3), what I call the ‘argument from phenomenal-concept acquisition’. Finally, I briefly present some reasons why my distinction may be important for various philosophical debates (§4).

The question of the unity of consciousness is often treated as the question of how different conscious experiences are related to each other in order to be unified. Many contemporary views on the unity of consciousness are based on this bottom-up approach. In this paper I explore an alternative, top-down approach, according to which (to a first approximation) a subject undergoes one single conscious experience at a time. From this perspective, the problem of unity of consciousness becomes rather the problem of how we can distinguish a multiplicity of goings-on within our conscious experience at any time, given that it is unique. I will present three possible top-down approaches to unity of consciousness, which I call Priority unity monism, Existence unity monism, and Brentanian unity monism. Priority monism and Existence monism are defined in analogy with the homonymous metaphysical theories of object constitution. Brentanian monism retraces Franz Brentano’s view on unity of consciousness, and is defined by appeal to some of his mereological ideas. I will argue that the latter is the best top-down approach to unity of consciousness.
