It is commonly assumed that besides knowledge of facts or truths, there is also knowledge of things–for example, we say that we know people or know places. We could call this "objectual knowledge". In this paper, I raise doubts about the idea that there is a sui generis objectual knowledge that is distinct from knowledge of truths.

In his recent paper ‘Knowing What Things Look Like’, Matthew McGrath offers a challenge to the idea that knowing an object by seeing it, ‘visual objectual knowledge’ is an instance of immediate knowledge. I offer supporters of the notion of immediate visual objectual knowledge two potential strategies for blocking McGrath’s argument: either by questioning McGrath’s claim about the role that knowing what an object looks like plays in visual objectual knowledge or by denying (...) that any explanation of how knowing what an object looks like plays that role must proceed through an appeal to factual knowledge involving that object’s looks.

The paper argues that an account of understanding should take the form of a Carnapian explication and acknowledge that understanding comes in degrees. An explication of objectual understanding is defended, which helps to make sense of the cognitive achievements and goals of science. The explication combines a necessary condition with three evaluative dimensions: An epistemic agent understands a subject matter by means of a theory only if the agent commits herself sufficiently to the theory of the subject matter, and (...) to the degree that the agent grasps the theory (i.e., is able to make use of it), the theory answers to the facts and the agent’s commitment to the theory is justified. The threshold for outright attributions of understanding is determined contextually. The explication has descriptive as well as normative facets and allows for the possibility of understanding by means of non-explanatory (e.g., purely classificatory) theories. (shrink)

Vaidya has recently argued that while Husserl’s method for acquiring knowledge of essence through use of our imagination is subject to a vicious epistemic circle, we can still use the method to successfully attain objectual understanding of essence. In this paper, I argue that the Husserlian objectual understanding-based epistemology envisaged by Vaidya suffers from a similar epistemic circularity as its knowledge-based foil. I argue that there is a straight-forward solution to this problem, but then raise three (...) serious problems for an amended version of Vaidya’s proposal and any similar Husserlian epistemology of essence. The paper closes with some general reflections on applying the Husserlian method to the contemporary notion of essence and on the idea of refocusing the epistemology of essence on understanding instead of knowledge.

In this note, I would like to focus on the two central distinctions Inan draws between varieties of ignorance. One is the distinction between “objectual” and “propositional” ignorance, and the other is the distinction between “truth-ignorance” and “fact-ignorance,” which is a distinction between two types of propositional ignorance. According to Inan, appreciating these distinctions allow us to see what is wrong with the “received view,” according to which ignorance (or awareness of it) is “always about truth,” and enables us (...) to “overcome our [philosophers’] propositional-bias.” I will argue for two theses. First, fact-ignorance appears to be a form of objectual ignorance; and, if this is so, there are no two distinctions but only one distinction that Inan in effect offers, which is between objectual and propositional ignorance. Second, what Inan calls “the received view” can raise some reasonable worries about objectual ignorance that are not taken into account by him. (shrink)

In science and philosophy, a relatively demanding notion of understanding is of central interest: an epistemic subject understands a subject matter by means of a theory. This notion can be explicated in a way which resembles JTB analyses of knowledge. The explication requires that the theory answers to the facts, that the subject grasps the theory, that she is committed to the theory and that the theory is justified for her. In this paper, we focus on the justification condition (...) and argue that it can be analyzed with reference to the idea of a reflective equilibrium. (shrink)

Duncan Pritchard (2008, 2009, 2010, forthcoming) has argued for an elegant solution to what have been called the value problems for knowledge at the forefront of recent literature on epistemic value. As Pritchard sees it, these problems dissolve once it is recognized that that it is understanding-why, not knowledge, that bears the distinctive epistemic value often (mistakenly) attributed to knowledge. A key element of Pritchard’s revisionist argument is the claim that understanding-why always involves what he calls strong (...) cognitive achievement—viz., cognitive achievement that consists always in either (i) the overcoming of a significant obstacle or (ii) the exercise of a significant level of cognitive ability. After outlining Pritchard’s argument, we show (contra Pritchard) that understanding-why does not essentially involve strong cognitive achievement. Interestingly, in the cases in which understanding-why is distinctively valuable, it is (we argue) only because there is sufficiently rich objectual understanding in the background. If that’s right, then a plausible revisionist solution to the value problems must be sensitive to different kinds of understanding and what makes them valuable, respectively. (shrink)

If there is any consensus about knowledge in contemporary epistemology, it is that there is one primary kind: knowledge-that. I put forth a view, one I find in the works of Aristotle, on which knowledge-of – construed in a fairly demanding sense, as being well-acquainted with things – is the primary, fundamental kind of knowledge. As to knowledge-that, it is not distinct from knowledge-of, let alone more fundamental, but instead a species of it. To (...) know that such-and-such, just like to know a person or place, is to be well-acquainted with a portion of reality – in this case a fact. In part by comparing classic Gettier cases to cases in which one has true impressions of but fails to know a person, I argue that this account not only respects our intuitions about knowledge-that – in particular that it is or entails non-accidentally true justified belief – but also explains them, providing a compelling analysis.

Determiner phrases embedded under a propositional attitude verb have traditionally been taken to denote answers to implicit questions. For example, 'the capital of Vermont' as it occurs in 'John knows the capital of Vermont' has been thought to denote the proposition which answers the implicit question 'what is the capital of Vermont?' Thus, where 'know' is treated as a propositional attitude verb rather than an acquaintance verb, 'John knows the capital of Vermont' is true iff John knows that Montpelier is (...) the capital of Vermont. The traditional view lost its popularity long ago, because it was thought to rest on the controversial assumption that determiner phases embedded under a propositional attitude verb function semantically in the same way as the corresponding wh-clauses. Here we defend the traditional assumption against objections. We then argue that wh-clauses are not to be given a uniform treatment as indirect questions. When occurring under a propositional attitude verb, wh-clauses are better treated as having a predicate-type semantic value. We conclude by considering some possible objections to the predicate view.

This work treats the correlative concepts knowledge and opinion, in various senses. In all senses of ‘knowledge’ and ‘opinion’, a belief known to be true is knowledge; a belief not known to be true is opinion. In this sense of ‘belief’, a belief is a proposition thought to be true—perhaps, but not necessarily, known to be true. All knowledge is truth. Some but not all opinion is truth. Every proposition known to be true is believed to (...) be true. Some but not every proposition believed to be true is known to be true. Our focus is thus on propositional belief (“belief-that”): the combination of propositional knowledge (“knowledge-that”) and propositional opinion (“opinion-that”). Each of a person’s beliefs, whether knowledge or opinion, is the end result of a particular thought process that continued during a particular time interval and ended at a particular time with a conclusive act—a judgment that something is the case. This work is mainly about beliefs in substantive informative propositions—not empty tautologies. We also treat objectual knowledge (knowledge of objects in the broadest sense, or “knowledge-of”), operational knowledge (abilities and skills, “knowledge-how-to”, or “know-how”), and expert knowledge (expertise). Most points made in this work have been made by previous writers, but to the best of our knowledge, they have never before been collected into a coherent work accessible to a wide audience. -/- Key words: belief, knowledge/opinion, propositional, operational, objectual, cognition, .

It has been widely accepted since Stanley and Williamson (2001) that the only linguistically acceptable semantic treatments for sentences of the form ‘S knows how to V’ involve treating the wh-complement ‘how to V’ as an interrogative phrase, denoting a set of propositions. Recently a number of authors have suggested that the ‘how to V’ phrase denotes not a proposition, but an object. This view points toward a prima facie plausible non-propositional semantics for knowledge-how, which treats ‘how to V’ (...) as a free relative noun phrase. In this paper I argue that the free relative semantics is implausible. I show that linguistic phenomena which seem to support a free relative semantics can be explained by the supporter of an interrogative semantics, and demonstrate that standard linguistic tests strongly suggest that ‘how to V’ has an interrogative reading, and no free relative reading.

According to a prominent account of knowledge-how, knowledge-how is a species of propositional knowledge. A related view has it that to know how to perform an action is for it to seem to one that a way to perform that action is in fact a way to do so. According to a further view, knowledge-how is a species of objectual knowledge. Each of these intellectualist views has significant virtues including, notably, the ability to account (...) for the seemingly epistemic dimensions of knowledge-how. However, while intellectualist views can account for the seemingly epistemic dimensions of knowledge-how, such views have difficulty accounting for the practical dimensions of knowledge-how. The objection I level against existing intellectualist views here seizes on this deficiency. I argue that, in virtue of the practical dimensions of knowledge-how, propositional knowledge under a practical mode of presentation is not sufficient for knowledge-how. Even when the sufficiency conditions for knowledge-how set out by extant intellectualist views are met, one may fail to know how to perform an action in virtue of a disposition to act on a false belief about a way for one to perform that action. Thus, whereas critics of intellectualist views often allege that such views place overly demanding conditions on knowledge-how, the objection developed here suggests that existing intellectualist views place insufficiently demanding conditions on knowledge-how.

I develop the relatively familiar idea of a variety of forms of knowledge —not just propositional knowledge but also knowledge -how and experiential knowledge —and show how this variety can be used to make interesting sense of Plato’s and Aristotle’s philosophy, and in particular their ethics. I then add to this threefold analysis of knowledge a less familiar fourth variety, objectual knowledge, and suggest that this is also interesting and important in the understanding (...) of Plato and Aristotle.

Propositionalism explains the nature of knowledge-how as follows: P: To know how to ϕ is to stand in a special propositional attitude relation to propositions about how to ϕ. To know how to ride a bike is to have the required propositional attitude to propositions about how to do so. Dispositionalism offers an alternative view.D: To know how to ϕ is to stand in a behavioral-dispositional relation, a being-able-to relation, to ϕ-ing. To know how to ride a bike is (...) to have an ability to do so in the form of a complex disposition to behave in ways that constitute bike riding. Objectualism presents a third option.O: To know how to ϕ is to stand in a non-propositional, non-behavioral-dispositional objective attitude relation to a way of j-ing. To know how to ride a bike is to have an objectual attitude, perhaps a form of knowledge of, to a way of doing so.Dispositionalism is often dismissed on the basis of two criticisms designed to show its shortcomings relative to Propositionalism and Objectualism. According to the Epistemic Improvement Objection, Dispositionalism cannot account for the fact that gaining knowledge-how is an improvement in our epistemic state. According to the Modified Ability Objection, it cannot account for the fact that being able to do something is neither necessary nor sufficient for knowing how to do it. I develop a form of Dispositionalism, the Special Ability View, that avoids both objections. (shrink)

This paper aims to construct a picture of knowledge out of Frege’s comments on truth, judgment, assertion, and knowledge. Frege takes truth to be an object, and the act of judgment to be the act of non-judgmental identification of truth qua an object with the reference of a sentence. For him, the propositional knowledge that p is the non-propositional knowledge of the identity between truth and |p|. Propositional knowledge thusly understood is produced by our (...) class='Hi'>knowledge of truth qua an object, which is constituted by our abilities to identify truth as such. The Fregean picture of knowledge provides a tight connection between knowledge-how, objectual knowledge, and propositional knowledge. (shrink)

What does it mean to understand something? I approach this question by comparing understanding with knowledge. Like knowledge, understanding comes, at least prima facia, in three varieties: propositional, interrogative and objectual. I argue that explanatory understanding (this being the most important form of interrogative understanding) and objectual understanding are not reducible to one another and are neither identical with, nor even a form of, the corresponding type of knowledge (nor any other type of knowledge). (...) My discussion suggests that definitions of the concepts of explanatory and of objectual understanding must include a commitment condition, a grasping condition, an answering-the-facts condition, and an epistemically internal justification condition, but no further external anti-luck condition. On this basis I argue against reducing explanatory understanding to propositional understanding, and in favour of identifying propositional understanding with propositional knowledge. (shrink)

Is understanding the same as or at least a species of knowledge? This question has to be answered with respect to each of three types of understanding and of knowledge. I argue that understanding-why and objectual understanding are not reducible to one another and neither identical with nor a species of the corresponding or any other type of knowledge. My discussion reveals important characteristics of these two types of understanding and has consequences for propositional understanding.

How are we to understand philosophical claims about sense perception being direct versus indirect? There are multiple relevant notions of perceptual directness, so I argue. Perception of external objects may be direct on some notions, while indirect on others. My interest is with the sense in which ideas count as perceptual mediators in the philosophy of Descartes and Locke. This paper has two broader aims. The first is to clarify four main notions of perceptual directness. The second is to support (...) my contention that in the texts characterizing ideas as immediate objects of perception, Descartes and Locke are invoking the notion of directness I call ‘objectual’. This notion is modeled on the way a picture mediates perception of the pictured object. The upshot of my account is that – with respect to the objectual notion of directness – Descartes and Locke each hold an indirect theory of perception. (shrink)

The idea of dignity seems indissociable from that of humanity, whether in its universal dimension of ‘human dignity’, or in the individual ‘dignity of the person’. This paper provides an outlook on the ethics governing the sciences and technology, in particular the biological sciences and biotechnology, and recalls the notion of ‘glory’, both human and divine, as it infuses a great part of the Middle Ages and the Renaissance cultures, just before the scientific revolution in Europe.

What is it to know someone? Epistemologists rarely take up this question, though recent developments make such inquiry possible and desirable. This paper advances an account of how such interpersonal knowledge goes beyond mere propositional and qualitative knowledge about someone, giving a central place to second-personal treatment. It examines what such knowledge requires, and what makes it distinctive within epistemology as well as socially. It assesses its theoretic value for several issues in moral psychology, epistemic injustice, and (...) philosophy of mind. And it offers an account of the complex content in play if interpersonal knowledge is to be understood in terms of its mental states and their functions. (shrink)

In ‘Knowing What Things Look Like,’ I argued against the immediacy of visual objectual knowledge, i.e. visual knowledge that a thing is F, for an object category F, such as avocado, tree, desk, etc. Joseph Shieber proposes a challenging dilemma in reply. Either knowing what Fs look like requires having concepts such as looks or it doesn’t. Either way my argument fails. If knowing what Fs look like doesn’t require having such concepts, then he claims we can (...) give an immediacy-friendly anti-intellectualist account of knowing what Fs look like, one that I neglected. If it does require having such concepts, then knowledge of what Fs look like plays no important role in ordinary cases of knowing things to be F by their looks. I argue for several claims. First, Shieber's anti-intellectualist proposal fails for independent reasons. Second, I give reasons for thinking that knowing what Fs look like doesn't require having a general concept of looks, which lessens worries about nonhuman animals having such knowledge. Finally, I consider the possibility, important to Shieber's argument, that nonhuman animals are simply incapable of knowing what Fs look like. I argue the implications for human knowledge are far from clear. (shrink)
