The internet has become an ubiquitous epistemic source. However, it comes with several drawbacks. For instance, the world wide web seems to foster filter bubbles and echo chambers and includes search results that promote bias and spread misinformation. Richard Heersmink suggests online intellectual virtues to combat these epistemically detrimental effects . These are general epistemic virtues applied to the online environment based on our background knowledge of this online environment. I argue that these online intellectual virtues also demand a particular view of cognitive integration. Online intellectual virtues are incompatible with a popular conception of extended minds proposed by Andy Clark and David Chalmers . I suggest that if we want to hold on to both a conception of online intellectual virtues and some conception of the extended mind, we have to accept a more gradual theory of cognitive integration along the lines of second-wave theories of the extended mind.

Clark and Chalmers propose that the mind extends further than skin and skull. If they are right, then we should expect this to have some effect on our way of knowing our own mental states. If the content of my notebook can be part of my belief system, then looking at the notebook seems to be a way to get to know my own beliefs. However, it is at least not obvious whether self-ascribing a belief by looking at my notebook is a case of introspection the same way that knowing my non-extended beliefs is. Traditionally this sort of introspection is thought to be privileged and special in ways that the extended introspection case seems not to be. There is nothing privileged about looking at my notebook. Anyone could do it. The aim of the paper is to find out how to understand extended introspection and whether there is something privileged and special about knowing one’s own extended beliefs. Moreover, the notebook case has close analogs using twenty-first century technology. It seems possible to know our beliefs that are extended to smartphones, wearable technology or a cloud-based data store. First, I present the case of extended introspection. I then discuss whether it should be understood as ordinary introspection or as mind-reading. Both seem to be bad fits, which finally prompts an original account for extended introspection based on epistemic rules.

Joint acceptance accounts of group belief hold that groups can form a belief in virtue of the group members jointly accepting a proposition. Recently, Jennifer Lackey (2020, 2021) proposed a challenge to these accounts. If group beliefs can be based on joint acceptance, then it seems difficult to account for all instances of a group telling a lie. Given that groups can and do lie, our accounts of group belief better not result in us misidentifying some group lies as normal assertions. I argue that Lackey’s argument is not decisive. The cases she proposes as challenges for joint acceptance accounts can be dealt with in the joint acceptance framework. I present two different readings of Lackey’s central case, showing that in both readings Lackey’s example of a problematic group lie should not be identified as a lie, but rather as an epistemic mistake by the group. What kind of mistake the group makes depends on the exact reading of Lackey’s case, but either way the group is not telling a lie.

When does a group justifiedly believe that p? One answer to this question has been developed first by Schmitt and then by Hakli: when the group members jointly accept a reason for the belief. Call this the joint acceptance account of group justification. Their answer has great explanatory power, providing us with a way to account for cases in which the group's justification can diverge from the justification individual members have. Unfortunately, Jennifer Lackey developed a powerful argument against joint acceptance accounts. She argues that these accounts lead to epistemically arbitrary reasons and therefore justification at will. Group justification loses the necessary connection to the world to be truth-conducive. In this paper I develop a new form of a joint acceptance account that can deal with Lackey's examples: the anchored joint acceptance account of group justification. I argue that properly understanding the role of epistemic expectations can help us form the best version of a joint acceptance account. While justification is only generated by joint acceptance of evidence, the evidential expectations towards a group are anchored in the group members. This anchoring guarantees that groups cannot manipulate their ultima facie justification illegitimately.

I discuss how virtual reality can be used to acquire self-knowledge. Lawlor (Philos Phenomenol Res 79(1):47–75, 2009) and Cassam (Vices of the mind: from the intellectual to the political. OUP, Oxford, 2014) develop inferential accounts of self-knowledge in which one can use imagination to acquire self-knowledge. This is done by actively prompting imaginary scenarios and observing one’s reactions to those scenarios. These reactions are then used as the inferential basis for acquiring self-knowledge. I suggest that the imaginary scenarios can be in principle replaced with scenarios in virtual reality in a way that still provides an inferential basis for self-knowledge. Instead of internal prompting in imagination, I call this external prompting in virtual reality. I discuss the advantages and disadvantages of external prompting. On one hand, external prompting avoids some of the common biases that can intervene with internal prompting in imagination. On the other hand, external prompting comes with some challenges of its own. External prompting might be more time-consuming and might be open to a game-like approach of the agent leading to a different sort of distortion that gets in the way of self-knowledge. I suggest that these are practical challenges, but nevertheless, external prompting seems worthwhile for self-knowledge that is otherwise especially difficult to acquire.

We seem to ascribe mental states and agency to groups. We say ‘Google knows such-and-such,’ or ‘Amazon intends to do such-and-such.’ This observation of ordinary parlance also found its way into philosophical accounts of social groups and collective intentionality. However, these discussions are usually quiet about how groups self-ascribe their own beliefs and intentions. Apple might explain to its shareholders that it intends to bring a new iPhone to the market next year. But how does Apple know what it intends? How do groups get to know their own mental states? This is the question of collective self-knowledge. I argue that collective self-knowledge is a distinct phenomenon that deserves our attention. In particular I suggest: that we should be interested in collective self-knowledge, because our behaviour indicates that we already engage with collective self-knowledge in practice; that groups can collectively avow, which indicates that they have privileged and peculiar access to their own intentional states; and that collective self-knowledge is not reducible to intentional states of individuals and therefore is an independent explanandum.

Groups can be epistemically vicious just like individuals. And just like individuals, groups sometimes want to do something about their vices. They want to change. However, intentionally combating one’s own vices seems impossible without detecting those vices first. Self-knowledge seems to provide a first step towards changing one’s own epistemic vices. I argue that groups can acquire self-knowledge about their epistemic vices and I propose an account of such collective self-knowledge. I suggest that collective self-knowledge of vices is partially based on evidence that a group can generate by performing internal promptings. Whereas these promptings are done mentally in individual self-knowledge, these promptings are done by interactions of group members in the collective case. The group can then acquire inferential self-knowledge of their vices based on the evidence generated by the interactions within the group. Groups thereby bring themselves into a position from which they can combat and change those vices intentionally.

This chapter discusses a problematic relation between user-friendly design and manipulation. Some specific features of the design of a website can make it a more or less potent tool for manipulation. In particular, features that can be summed up as creating a user-friendly experience are also manipulation-friendly. The ease of using a website also makes it easier to be manipulated via the website. The chapter provides an argument that this can be explained as a less intellectually virtuous engagement with websites that are more user-friendly. It is simply more difficult to mobilize suitable intellectual virtues when the website is quick and easy to use. For instance, when Google Search presents search results quickly and easily users become less intellectually cautious and independent than they ought to be. The chapter discusses a mechanism that links user-friendly design to an overly trusting attitude towards a website that leads to this intellectually careless behaviour. This link is support with empirical evidence based on processing fluency effects.

Jennifer Lackey (2016) challenged group acceptance accounts of justification by arguing that these accounts make the possession of evidence arbitrary and hence lead to illegitimate manipulation of the group's evidence. She proposes that the only way out is to rely on the epistemic propriety of the individual group members, which leads to a dilemma for group acceptance views: either they are wrong about justification, or they cease to rely only on group acceptances. I argue that there is a third option based on general expectations of epistemic propriety that restricts the group's maximal justification. A group cannot be more justified than any individual in the group's position could be expected to be. I motivate this solution by a discussion of normative defeat and epistemic expectations as proposed by Goldberg (2018).

Adam Carter (2022) recently proposed that a successful analysis of knowledge needs to include an autonomy condition. Autonomy, for Carter, requires a lack of a compulsion history. A compulsion history bypasses one’s cognitive competences and results in a belief that is difficult to shed. I argue that Carter’s autonomy condition does not cover partially autonomous beliefs properly. Some belief-forming processes are partially bypassing one’s competences, but not bypassing them completely. I provide a case for partially autonomous belief based on processing fluency effects and argue that partially autonomous beliefs only amount to knowledge in some cases. I finally suggest how to adjust the autonomy condition to capture partially autonomous belief properly.

In this paper I propose an account of self-knowledge based on a framework of predictive processing. Predictive processing understands the brain as a prediction-action machine that tries to minimize error in its predictions about the world. For this view to evolve into a complete account of human cognition we ought to provide an idea how it can account for self-knowledge – knowledge of one’s own mental states. I provide an attempt for such an account starting from remarks on introspection made by Hohwy. I develop Hohwy’s picture into a general model for knowledge of one’s mental states, discussing how predictions about oneself can be used to capture self-knowledge. I further explore empirical predictions, and thereby argue that the model provides a good explanation for failure of self-knowledge in cases involving motor aftereffects, such as the broken escalator phenomenon. I conclude that the proposed account is incomplete, but provides a valuable first step to connect research on predictive processing with the epistemology of self-knowledge.

Wright (1998) and Bar-On (2004) put pressure on the idea that self-knowledge as an explanandum should be identified with privileged belief formation. They argue that setting up the discourse on the level of belief and belief formation rules out promising approaches to explain self-knowledge. Hence, they propose that we should characterize self-knowledge on the level of linguistic practice instead. I argue against them that self-knowledge cannot be fully characterized by features of our linguistic practice. I propose that in some circumstances – disagreements about one's mental states – self-knowledge plays a role, but this role cannot be described in virtue of features of our linguistic practice. I consider three objections to the argument and conclude that we should not conceive self-knowledge solely in terms of linguistic practice.

In 'The Grasshopper' Suits proposes that ‘playing a game’ can be captured as an attempt to achieve a specific state of affairs (prelusory goal), using only means permitted by rules (lusory means). These rules prohibit more efficient means, and are accepted because they make the activity possible (lusory attitude). I argue these conditions are not jointly sufficient. The starting point for the argument is the idea that goals, means and attitudes can pick out their content in different ways. They can involve a direct reference (‘crossing this specific finish line’), or a description that picks out something (‘crossing a line on the track after running 100 m’). I provide cases in which one’s attitudes, accepted goals or accepted means pick out their content by a description such that the person does not play a game, even if Suits’s conditions are satisfied. I show that this demands an epistemic condition for playing a game that also applies to commitment based accounts. Finally, I discuss what such an epistemic condition could be. I argue that the condition does not require personal knowledge of all goals and means, but merely enough epistemic access that the goal and permissible means can guide one’s behavior safely enough. This might be satisfied by social extensions, such as access to tools (e.g. a rulebook) or other people (e.g. referees).

In this thesis I propose an account of knowledge of one’s own mental states. My goal is set on a unified transparency account of self-knowledge. It is unified, because the proposal will account for the generation of beliefs about mental states of all types, regardless of whether they are propositional, non-propositional, experiential or non-experiential. My account will thereby be applicable to knowledge of any mental state, from beliefs and desires to fears, hopes, and sensations such as pain. Moreover, it will be a transparency account because it holds on to Gareth Evans’s observation that self-ascribing mental states is done by attending outwards instead of inwards. There is a sense in which we attend to the world when we find out whether we believe something, and my proposal aims to capture this intuition. The core idea I am exploring is the following: generally, when one produces a first-order mental state, one also forms a corresponding, dispositional second-order belief about that state. Both attitudes share elements of their production, which ensures reliability while retaining fallibility. For instance, when you form a belief ‘there is a red car’ by perceiving a red car, you also generate the dispositional belief ‘I believe that there is a red car,’ if everything goes right. I argue that almost all features that make self-knowledge special can be explained with this basic idea. The assumption that the production of a first-order mental state and a second-order belief about the state go hand in hand has surprising explanatory power. Moreover, there are at least no obvious reasons why the assumption should be ruled out. The upshot will be a view that we should take seriously as a contender for an explanation of self-knowledge. I will not be able to conclusively show that it is the best explanation, but I argue that it is one worth thinking about. The thesis is structured in three parts. The first part focuses on the phenomenon of self-knowledge and the transparency idea. These chapters serve as the setup for my later proposed view. Chapter 1 and 2 discuss what exactly we want to explain when we say that we aim to explain self-knowledge. I thereby provide an overview of the conceptual landscape of self-knowledge and argue that we should understand the peculiarity of self-knowledge in terms of features of belief and belief-formation. Moreover, I commit myself to the view that the peculiarity has something to do with our cognitive access to mental states and relate that to the goal of a unified account of self-knowledge. Chapter 3 discusses how we ought to understand the other qualification of my goal: a transparency account of self-knowledge. I provide an overview of transparency accounts in the literature and lay out the path to avoid common problems of transparency accounts. In the second part I propose the single process model of self-knowledge as a unified, transparency account of self-knowledge. I provide the core principles of the view and show how it explains the features of self-knowledge I aim to explain. Chapter 4 focuses on attitudes, both propositional and non-propositional. Chapter 5 expands the view to phenomenal states, such as being in pain. The third part connects the epistemological discussion of the single process model to research on cognition. Chapter 6 proposes a cognitive story of predictive processing that is compatible with the single process model. I thereby discuss the plausibility of the predictive processing idea and its empirical support. I provide a predictive processing story of self-knowledge that fits with the single process model of self-knowledge. In chapter 7 I discuss extended mental states. Clark & Chalmers propose that at least some mental states, such as beliefs, can be extended to external devices. Given that my aim is a unified account, I ought to say something about knowledge of these extended beliefs. I argue that they cannot be known by the same processes as non-extended mental states because beliefs about extended beliefs show different features than beliefs about our non-extended states that we formed by introspection. Hence, even if my view cannot account for them this is not a problem, because they are not formed by genuine introspection. Instead, we come to know extended mental states by a distinct process that we might call extended introspection. Finally, chapter 8 provides a brief conclusion of the thesis for and points out some placed that require further development. The account is promising as an explanation of self-belief and self-knowledge, but whether it is correct also depends on future research outside the scope of philosophy.

This paper closes a gap in joint acceptance accounts of the mental life of groups by presenting a theory of group self-knowledge in the joint acceptance framework. I start out by presenting desiderata for a theory of group self-knowledge. Any such theory has to explain the linguistic practice of group avowals, and how self-knowledge can play a role in practical and moral considerations. I develop an account of group self-knowledge in the joint acceptance framework that can explain these desiderata. I argue that a group has self-knowledge of its own attitude A if and only if (i) the operative members jointly accept that the group has attitude A; and (ii) that joint acceptance is non-deviantly caused by the operative group members’ belief that the members jointly accepted attitude A; and (iii) the group has attitude A. Together (i) to (iii) give us conditions for a group having a justified, non-lucky, true belief about its own attitude.
