The topic of introspection stands at the interface between questions in epistemology about the nature of self-knowledge and questions in the philosophy of mind about the nature of consciousness. What is the nature of introspection such that it provides us with a distinctive way of knowing about our own conscious mental states? And what is the nature of consciousness such that we can know about our own conscious mental states by introspection? How should we understand the relationship between consciousness and introspective self-knowledge? Should we explain consciousness in terms of introspective self-knowledge or vice versa? Until recently, questions in epistemology and the philosophy of mind were pursued largely in isolation from one another. This volume aims to integrate these two lines of research by bringing together fourteen new essays and one reprinted essay on the relationship between introspection, self-knowledge, and consciousness.

There is surprising evidence that introspection of our phenomenal states varies greatly between individuals and within the same individual over time. This puts pressure on the notion that introspection gives reliable access to our own phenomenology: introspective unreliability would explain the variability, while assuming that the underlying phenomenology is stable. I appeal to a body of neurocomputational, Bayesian theory and neuroimaging findings to provide an alternative explanation of the evidence: though some limited testing conditions can cause introspection to be unreliable, mostly it is our phenomenology itself that is variable. With this account of phenomenal variability, the occurrence of the surprising evidence can be explained while generally retaining introspective reliability.

Abstract If we take for granted that introspection is indispensable for the study of conscious mental states, the question arises what criteria have to be met in order for introspective reports to qualify as scientific evidence. There have been some attempts to argue (implicitly or explicitly) that it is possible to provide a satisfactory answer to this question while remaining agnostic with respect to questions about the nature of consciousness. Focusing on the aim of using introspection in order to generate phenomenological descriptions of conscious mental states, this paper argues that such an agnostic stance cannot be maintained, because the very meaning of ?introspection? remains fuzzy as long as we don't have a clear understanding of how the mind does it. I show that current debates revolve around some of the same issues that were already in the background of debates around 1900, and I argue that a satisfactory treatment of introspection as a method cannot be separated from the aim of providing a satisfactory treatment of introspection as a feature of consciousness.

Poverty of the Stimulus Arguments have convinced many linguists and philosophers of language that a domain specific language acquisition device (LAD) is necessary to account for language learning. Here we review empirical evidence that casts doubt on the necessity of this domain specific device. We suggest that more attention needs to be paid to the early stages of language acquisition. Many seemingly innate language-related abilities have to be learned over the course of several months. Further, the language input contains rich stochastic information that can be accessed by domain-general learning mechanisms. Computer simulation has shown how mechanisms that are not domain specific can exploit the information contained in language. We conclude that (i) Poverty of the Stimulus Arguments need to be conceptually clarified and (ii) more empirical research needs to be carried out before we can rule out that data driven general purpose mechanisms can account for language learning.

recent cognitive theories into two antagonistic groups. Sententialists claim that we think in some language, while advocates of non-linguistic views of cognition deny this claim. The Introspective Argument for Sententialism is one of the most appealing arguments for sententialism. In substance, it claims that the introspective fact of inner speech provides strong evidence that our thoughts are linguistic. This article challenges this argument. I claim that the Introspective Argument for Sententialism confuses the content of our thoughts with their vehicles: while sententialism is a thesis about the vehicles of our thoughts, inner speech sentences are the content of auditory or articulatory images. The rebuttal of the introspective argument for sententialism is shown to have a general significance in cognitive science: introspection does not tell us how we think.

This article analyzes Wittgenstein’s position on the grammatical incorrigibility of psychological self-ascriptions and shows how introspective statements can be of use to philosophers. In Wittgenstein On Rules and Private Language, Kripke notes Wittgenstein’s puzzling ambivalence toward introspection. On the one hand Wittgenstein repudiates introspection and on the other he uses it in his own philosophical investigations. To resolve the paradox, this paper distinguishes between introspective methodology in psychological and philosophical investigations. Wittgenstein’s arguments against introspection are specifically directed at introspective methodology in psychology. He argues that the use of introspection to discover “inner causes” commits one to a conception of “direct inner awareness”. On that conception, psychological self-ascriptions are considered highly reliable due to the superiority of the subjective vantage point in ascertaining one’s own mental contents. As an alternative, Wittgenstein maintains that this reliability stems from the grammar of the ascription. The paper places Wittgenstein’s alternative conception of incorrigibility into the context of his argument against the use of introspection in psychology.

Introspective reports are used as sources of information about other minds, in both everyday life and science. Many scientists and philosophers consider this practice unjustified, while others have made the untestable assumption that introspection is a truthful method of private observation. I argue that neither skepticism nor faith concerning introspective reports are warranted. As an alternative, I consider our everyday, commonsensical reliance on each other’s introspective reports. When we hear people talk about their minds, we neither refuse to learn from nor blindly accept what they say. Sometimes we accept what we are told, other times we reject it, and still other times we take the report, revise it in light of what we believe, then accept the modified version. Whatever we do, we have (implicit) reasons for it. In developing a sound methodology for the scientific use of introspective reports, we can take our commonsense treatment of introspective reports and make it more explicit and rigorous. We can discover what to infer from introspective reports in a way similar to how we do it every day, but with extra knowledge, methodological care, and precision. Sorting out the use of introspective reports as sources of data is going to be a painstaking, piecemeal task, but it promises to enhance our science of the mind and brain.

Most ?theories of consciousness? are based on vague speculations about the properties of conscious experience. We aim to provide a more solid basis for a science of consciousness. We argue that a theory of consciousness should provide an account of the very processes that allow us to acquire and use information about our own mental states ? the processes underlying introspection. This can be achieved through the construction of information processing models that can account for ?Type-C? processes. Type-C processes can be specified experimentally by identifying paradigms in which awareness of the stimulus is necessary for an intentional action. The Shallice (1988b) framework is put forward as providing an initial account of Type-C processes, which can relate perceptual consciousness to consciously performed actions. Further, we suggest that this framework may be refined through the investigation of the functions of prefrontal cortex. The formulation of our approach requires us to consider fundamental conceptual and methodological issues associated with consciousness. The most significant of these issues concerns the scientific use of introspective evidence. We outline and justify a conservative methodological approach to the use of introspective evidence, with attention to the difficulties historically associated with its use in psychology.
