But we need not rely on fantastical envatted brain scenarios to make this style of objection to (KFVE-Proficiency). Sylvan (2018), and Lord (2018) each take a reasons-first approach to justification, on which justified belief just is belief that is held for sufficient reason: (J=SR) Ss belief that p is Justification | philosophy | Britannica It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. For more on unreasonable knowledge see Lasonen-Aarnio (2010, 2014) and Benton and Baker-Hytch (2015).). Column: The right-wing campaign to make our kids dumber In good inductive reasoning, if the premises are true (the input beliefs), then the conclusion is true. For example, Millar (2019) argues for a special instance of this in arguing that we cannot exercise an ability to know by perception without thereby acquiring perceptual knowledge. (See Silva (2017) for an extended discussion of how certain versions of KFVE can satisfy these desiderata.). Kelps view, roughly, amounts to this: (KFVE-Ability) S has a justified belief iff Ss belief is competent, where Ss belief is competent iff Ss belief is produced by an exercise of an ability to know. However, not all beliefs that follow from perception are guaranteed to be true, as the possibility of knowledge by acquaintance shows. WebThe main theories of justification include: Coherentism - Beliefs are justified if they First, (J=K) is incompatible with the fallibility of justification, that is, the possibility of having justified false beliefs. Whitcomb, D. 2014. According to foundationalism, the beliefs that make up the foundation are justified beliefs, but they are justified non-inferential beliefs. But it seems like misleading (non-factive) information can also defeat knowledge and justification. When we wonder whether knowledge of the external world is possible, what we really question is whether we can ever be justified in accepting as true our beliefs about the external world. But one can have justification to believe (L) on the basis of a newspaper report. 2014. One source of belief is memory. Rather, it is only proficient abilities to know (competences) that yield justified beliefs, and all abilities to know are proficient abilities to know. Here is Alexander Birds (2007) knowledge-first account of justification: (JuJu) If in world w1S has mental states M and then forms a judgment [or belief], that judgment [or belief] is justified iff there is some world w2where, with the same mental states M, S forms a corresponding judgment and that judgment [or belief] yields knowledge. For content externalism implies that any mental state duplicate of Ss who believes (c) on the basis of (a) and (b) will be a thinker for whom the terms Phosphorus and Venus refer to the very same astral body, thus making knowledge of (c) on the basis of (a) and (b) impossible. Foundational beliefs are supposed to be where the justification stops. If you see Sign in through society site in the sign in pane within a journal: If you do not have a society account or have forgotten your username or password, please contact your society. These two principles give us a knowledge-first theory of justification that avoids some of the main problems facing (J=K). However, it is not guaranteed that these beliefs are connected to reality. The fourth condition could instead be an internal condition. For librarians and administrators, your personal account also provides access to institutional account management. We might wonder, then, whether the envatted brains ability to know by perception is lost with the loss of her body and the bodys perceptual apparatus just as the gymnasts ability to do backflips is lost with the loss of her leg. But as discussed in the chapter on logic, not all forms of inference can guarantee truth. So suspension seems like the only rational response available to you. Provided ones evidence just is the set of reasons one has for belief, this leads to a view on which one possess p iff one knows p. This more restrictive knowledge-first view of possession together with (J=SR) and (J=K) constitute a kind of reasons-first, knowledge-first theory of justification. Thus, Ichikawas defense of (JPK) is susceptible to cases like the following: Bad Past: At t S comes to believe that there is a ceiling overhead. To illustrate the difference, suppose there is an infallible record of peoples heights. This is not true, but were it true it would defeat your knowledge; were it true you would be in a Gettier situation. Yet many philosophers think that Henry doesnt have knowledge given the lucky nature of his belief. This bucks against a history of strong intuitions to the contrary (Bird 2007; Comesana and Kantin 2010; Whitcomb 2014; Ichikawa 2014). Justification as the Appearance of Knowledge., Rosenkranz, S. 2007. On Miracchis (2015) preferred instance of (KFVE), exercises of abilities to know explain our justified beliefs but it is not mere abilities to know that have the potential yield justified beliefs. For a further justificatory asymmetry that certain knowledge-first approaches to justification can explain involving lottery and prefaces cases, see Dutant and Littlejohn (2020). (For the locus classicus on the concept of excuse see Austins A Plea for Excuses. For critical discussion of the excuse maneuver in defense of knowledge-first theories (of assertion and justification) see Lackey (2007), Gerken (2011), Kvanvig (2011), Schechter (2017), Madison (2018), and Brown (2018).). This threatens to make these views much more revisionary than they initially appeared to be. And for coherentists, logical consistency alone does not make a system of belief justified. Still, the misleading testimony that you are in fake-barn country gives you justification to believe that you are in fake-barn country. Replies to Critics. In Duncan Pritchard & Patrick Greenough (eds.). Describe the similarities and differences between coherentism and foundationalism. Williamson, T. 2014. Because of the detailed nature of Dinahs virtual reality, most of her beliefs are consistent with and support one another, just as your beliefs about the real world do. Must I also have reasons for believing the calculator is reliable before being justified in believing the answer? For qualified opposition see Horowitz (2014). But even overcoming the standard general worries with infinitism, knowledge-first infinitism will be especially difficult to handle due to luminosity failures for KK. Alternatively, one might seek to characterize being in a position to know in terms of having the disposition to know which is compatible with the existence of doxastic finks. Conee, E. 1994. Externalists hold that a subject need not have access to why their true beliefs are justified. If (KFVE-Ability) or (KFVE-Functionalism) imply that a recently envatted brain is able to have justified beliefs from an exercise of an ability to know or as a product of their cognitive competences which aim a knowledge, then it is easy to see how claims 4 and 5 will be verified by (KFVE-Ability) and (KFVE-Functionalism). When you make this determination, you reference that persons mental state (the lack of reasons). But that is the wrong result. Most beliefs are the product of inference. Perhaps surprisingly, the category of reasons-first, knowledge-first views cross-cuts some of the other categories. Our books are available by subscription or purchase to libraries and institutions. 1. Explain what justification means in the context of epistemology. Rather, there are various basic epistemic phenomena that are not reductively analyzable. Yet while justification is a reliable source, notice that this does not mean that the belief is true; it just makes it more likely. Brown and M. Simion (ed. WebFoundationalists have two main projects: a theory of proper basicality (that is, a theory of Conee, E. 1987. (JuJu) counts as a knowledge-first theory of justification because it explains ones justification in terms of the knowledge of ones mental state duplicates. are licensed under a, Socrates as a Paradigmatic Historical Philosopher, Critical Thinking, Research, Reading, and Writing, Overcoming Cognitive Biases and Engaging in Critical Reflection, Gathering Information, Evaluating Sources, and Understanding Evidence, The Early History of Philosophy around the World, Historiography and the History of Philosophy, Jewish, Christian, and Islamic Philosophy, Philosophical Methods for Discovering Truth, Contemporary Philosophies and Social Theories, Continental Philosophys Challenge to Enlightenment Theories, There are two different ways of conceptualizing belief structures: as a web of interconnected beliefs (left) and as a linear structure (right) in which foundational beliefs justify other beliefs, one after the other in a line. When you form beliefs based on the testimony of experts, it is justified. More precisely, coherentism argues that a belief is justified if it is embedded in a network of coherent, mutually supported beliefs. Aug. 22, 2023 5 AM PT. This aspect of (JPK) goes a long way towards making it internalist-friendly and also helps (JPK) avoid the difficulties facing (JuJu) and (J=K). So, if (PJPK) is true, you only have propositional justification to believe p if you actually believe p. But it is usually assumed that it is possible to have justification to believe p even if you do not believe p. To accommodate this (PJPK) will need revision. In contrast, on Simions (2019) view justified beliefs are beliefs that are generated by properly functioning cognitive processes that are aimed at yielding knowledge. The beliefs are coherent, and all support one another. Externalist theories about justification usually focus on the sources of justification, which include not only inference but also testimony and perception. D justifies A, but A justifies D through B and C. Circularity results in the beliefs not having any support at all. If it hadnt had the appearance of a Stellers Jay, I wouldnt have been able to remember that appearance later and match it to the photos and video of Stellers Jays. I think it is perfectly correct to say that the bird I saw had the appearance of a Stellers Jay, even though I didnt know that thats what it was at the time. Consider, for instance, the absurdity involved in believing p while also believing that one does not know p. Some explanation for the irrationality of this combination of beliefs should fall out of a theory of justification that tells us when and why a belief is (or is not) justified. As for 6 and 7, the virtue-theoretic machinery here is key. Foundationalism | Internet Encyclopedia of Philosophy ), Fratantonio, G. 2019. (For alternative characterizations of being in a position to know see Williamson 2000: 95; Rosenkranz 2007: 70-71.). Figure 7.5 offers a simplified visual of the two different structures of belief. A few caveats. I believe he is from Tennessee but am not sure. But it is not hard to see how a (J=K) theorist might accommodate propositional justification (Silva 2018: 2926): (PJ=PK) S has justification to believe p iff S is in a position to know p. What does it take to be in a position to know p? Do not use an Oxford Academic personal account. Beliefs that result from wishful thinking are not justified because wishful thinking does not make a belief more likely to be true. Here is a final perspectival, knowledge-first theory of justification. But that was exactly what was lacking in the cases discussed above that motivated 6 and 7. The second concern to have about (KFVE-Ability) and (KFVE-Functionalism) is that there is a question about the extent to which abilities/cognitive processes are in the head. For example, consider the amputee gymnast. Third, (J=K) is incompatible with the new evil demon hypothesis. Some Thoughts on the JK-Rule., Smithies, D. 2012. Unfortunately, you are the victim of an illusion, your demonstrative fails to refer, your premise sentence thereby fails to express a proposition, and your lack of a corresponding singular belief is a feature of your mental state, according to the content externalist. Because Smith can have justified false beliefs in the way described above, he can have a justified false belief that Jones will get the job based on the fact that the employer said so and the fact that this is a highly reliable indicator of who will get the job. For example, (J=K) theorists have tended to fall into this camp. Knowledge, Awareness, and the Possession of Reasons. University of Cologne. According to foundationalists, most beliefs are like the superstructure of the housethe frame, roof, and walls. Smithies (2012: 270) points out that, on this view, to lack justification one must be in a position to know that one is not in a position to know. We can summarize her view of justified belief, roughly, as follows: (KFVE-Proficiency) S has a justified belief iff Ss belief is competent, where Ss belief is competent iff Ss belief is produced by an exercise of a proficient ability to know. Justified belief is susceptible to defeat by justified defeating information. To return to the calculator example, the mere fact that a calculator is reliable can function as justification for forming beliefs based on its outputs. Gerken, M. 2018. This is at least a metaphysical possibility, and certainly a logical possibility. Knowledge as a Non-Normative Relation.. Silva, P. 2020. Second, consider some plausible claims about the normativity of belief. Second, (JuJu) fails to survive the Williamsonian counterexamples to internalism. Justification Logic - Stanford Encyclopedia of Philosophy The strongest objection against foundationalism targets the nature of basic beliefs. Another objection to coherentism is called the isolation objection. Simple K-Reliabilism replaces the justification clause in the traditional C. 2016. Dinahs situation reveals an important feature of justification: while justification makes beliefs more likely to be true, it does not always guarantee that they are true. Deductive reasoning takes as its input other beliefs to then derive conclusions. So if we are not to risk an unacceptable skepticism about doxastically justified belief (and hence knowledge), it seems we will either have to give up the tradition or treat the right-hand-side of (PJ=PJPK) as specifying a mere non-explanatory necessary and sufficient condition. The sufficiency direction, while rarely challenged, is also objectionable (Conee 1987, 1994; Silva 2018). Now the defeater pairing insight says that the fact that you justifiably believe the wall is illuminated by red lights defeats your justification to believe the wall is red. Justification makes a belief more likely to be true by providing reasons in favor of the truth of the belief. These include traditional foundationalism and variants thereof, externalist versions of foundationalism; contextualism; coherentism; and mixed theories which combine aspects of coherentism and foundationalism. So, this objection gives rise to a further potential demand on an adequate theory of justified belief: Desideratum 8. The no relevant alternatives theory adds to the traditional account of knowledge the requirement that a person rule out any competing hypotheses for their belief. Email: psilvajr@gmail.com How justification does this and how to think about the reasons will be discussed below. However, each plays a role in its own justification. Suppose you grew up in an environment with lots of beech trees and developed the ability to visually identify them and thus the ability to know that a beech tree is nearby by sight. There is non-trivial empirical reason to find this suspicious. Sutton (2005; 2007) has argued that grasping the concept of epistemic justification depends on our prior understanding of knowledge: We only understand what it is to be justified in the appropriate sense because we understand what it is to know, and can extend the notion of justification to non-knowledge only because they are would-be knowers. When on the institution site, please use the credentials provided by your institution. Not all philosophers agree that all perceptual beliefs are mediated through sense data (Crane and French 2021). (eds.). For similar reasons (KFVE-Know How) is able to satisfy Desiderata 4-7. But what if I used a calculator to derive the result? Of course, the weakness here is that the envatted brains perceptual belief that p is not based on her inferential source of propositional justification to believe p. Rather, the envatted brain holds her belief in response to her perceptual experience. Both problems stem from the attempt to reconcile (JPK) with the idea that justified belief is a type of creditable belief. Silins, N. 2007. If you are able to figure out whether the faucet is leaking and you use that ability, the typical result will be knowledge that the faucet is leaking (if it is leaking) or knowledge that the faucet is not leaking (if it is not leaking). This is not just a problem for (JuJu), but also (J=K). Click the account icon in the top right to: Oxford Academic is home to a wide variety of products. Suppose you need to go to the bank, and on your way out the door, your roommate tells you not to waste your time because they drove by the bank earlier and it was closed. For example, even before I had the concept of a Gettier Case, my evidence supported the claim that I exist or Im in a Gettier case just in virtue of the fact that I exist was already part of my evidence and entailed that disjunction. Unless one is in Hollywood, one would not think that facades are a distinct possibility.
