    1.WhatAreIntuitions?

    Considerthreethesesaboutperception:

    suchasyourimaginingsandconsciousthoughts.5

    Inmyviewintuitionissimilartoperceptionwithrespecttothefirsttwopoints,and

    dissimilarwithrespecttothethird.Thatis,Iendorsethefollowingthesesabout

    intuition:

    (4)Intuitionexperiencesaresuigenerisexperiences;theyshouldnotbeidentifiedwithdoxasticattitudesordispositionssuchasbeliefs,or

    inclinationstobelieve.6

    3Cf. (Jackson 1977), (Evans 1981), (Peacocke 1983), (Searle 1983), (Foster 2001), (Huemer 2001).

    (Armstrong 1968) is a well-known defense of the opposing view; see also (Gler 2009).

    4Cf. (McDowell 1994), (Robinson 1994), (Sturgeon 2000), (Foster 2001), (OShaughnessy 2002), (Crane2005), and (Johnston 2006). All agree that perception possesses presentational phenomenology, though

    not all adopt the same gloss on what this amounts to. I explore the nature of presentational

    phenomenology further in (Chudnoff 2012a).

    5Contrast the views of some earlier writers according to which perceptual experiencesas opposed tomere sensationsare supplemented by imagination. For discussion see Strawsons Imagination and

    Perception in (Strawson 2007).

    Ihavearguedfortheses(4)through(6)atlengthelsewhere.9HereIwillbriefly

    indicatesomemotivationforacceptingthem.

    Considerthefollowingtwoclaims:

    (A)Ifa0(B)7+10>3+17

    Both(A)and(B)aretruthswecancometoknow.Butthereisadifference.Formost

    ofus(B)isonlyknowablebycalculationortestimony.(A),ontheotherhand,is

    6Cf. (Bealer 1998, 2000, and 2002) and (Huemer 2001, 2008). For arguments in favor of the opposing

    view see: (Williamson 2004, 2005, and 2007) and (Earlenbaugh and Molyneux 2009).7This viewthough not my way of putting itwas more common among earlier writers on intuition. In

    (Chudnoff 2011b), I give reasons for attributing it to Descartes, Husserl, Russell, and Gdel. I would

    add certain moral intuitionists such as John Balguy and Richard Price to the list of historical

    proponents; see their works excerpted in (Raphael 1969). Among more recent writers, Butchvarov and

    Bonjour seem to me to defend similar views; see (Butchvarov 1970) and (Bonjour 2005).

    8Cf. (Husserl 1975, 2001), (Parsons 1980, 2007), and (Tieszen 1989, 2005). I believe Husserl was the firstto defend this view. It was common ground among those in the phenomenological tradition; see, for

    example, (Reinach 1911), (Gurwitsch 1964), and (Lvinas1995).9See (Chudnoff 2011a, b, and c, 2012a and b,andforthcoming).

    Considerthefollowingtwoarguments.

    ArgumentA

    21 How exactly to understand the becausal condition is an issue I will discuss below.22 Brewer seems to endorse such a becausal condition in (Brewer 1995).

    23 There might be a principlestronger than (II-) but weaker than (II) that best fits the conception ofinferential internalism Boghossion has in mind when he is arguing against the view. See footnote 27

    below. Since I am defending the stronger principle, (II), whether this is so does not matter for my

    purposes.

    24 I am partly inclined to think that Leite's response to Boghossian's Carrollian argument consists in doing

    precisely this: endorsing (II-), rejecting (II). See (Leite 2008), pages 429432. But I am not confident

    that this is a correct interpretation. Leite says that one's appreciation of the relation between premise and

    conclusion must play a role without doing something in one's inference. See page 432.

    (2)Todayisthe20th.(3)MarthaArgerichisplayingtodayinCarnegieHall.26

    25 The point I am making here parallels a more familiar point about justified belief. In order to have a

    justified belief that p it does not suffice to have a belief that p and justification for believing that p: one

    must base one's belief that p on one's justification for believing that p. For further discussion, see(Feldman and Conee 1985).

    26 The example is Boghossian's; (Boghossian 2003), page 267 in the reprint in (Boghossian 2008).

    27 (Boghossian 2003), page 274 in the reprint in (Boghossian 2008). It is because Boghossian takes this to

    be a question that inferential internalists must face that I believe he thinks inferential internalism iscommitted to more than (II

    -). But it is because there is a difference between an intuition bearing on one's

    warrant for inferring and an intuition bearing on one's inferring that I believe (II) might be too strong to

    capture his conception of inferential internalism. As pointed out above, this doesn't matter for my

    purposes. See footnote 30 for a reason to think a principle stronger than (II-) but weaker than (II) is still

    too weak.

    my inferring (3). Perhaps, then, this additional problem is off his radar.But it shouldn't be. Suppose theinferential internalist has a good story about how (iv) bears on my entitlement to infer (3). There is still

    the question: how does my entitlement to infer (3) bear on my inferring (3)? Just as one might possess

    evidence for a belief, but believe independently of it, say on the basis of wishful thinking, so one might

    possess entitlement for an inference, but infer independently of it, and so without transmitting

    justification from premises to conclusion. Again, see (Feldmanand Conee 1985) for discussion ofjustified belief.

    31 Compare: In making inferences, a being is ipso factoan agent (Burge 1998). (Peacocke 2008) and

    (Gibbon 2009) agree. (Strawson 2003) disagrees, and though (Mele 2009) does not discuss inference inparticular, he develops a position toward mental action in general that is similar to Strawson's. Strawson

    and Mele do agree with Burge, Peacocke, Gibbon, and myself on this much: when we make an

    inference we are doing something for which we are immediatelyresponsible. We are responsible andthis distinguishes inferences from sneezes and hiccups. And this responsibility is immediate in the sense

    that we are responsible and not just because we are responsible for some upstream cause of our

    inference. The assumption that inferences are mental events for which we are immediately responsible

    is likely strong enough for my purposes here. I cannot explore the issue in any further detail, however.

    32 In this I am in agreement with (Brewer 1995). It is worth emphasizing that being not merelycausal iscompatible with being causal.

    34 One might defend the view that intuition works like perception does in the context of a background

    activity by arguing that when we make inferences because of what we intuit we do so in the context of a

    background activity of thinking, or reasoning, or working our way toward an inference, or something

    else. This view seems implausible to me. Sometimes we just make an inference, and this isn't part ofany larger endeavor.

    37 If taking a perception at face value is a mental action, then (Inertia) requires qualification. Perhapssomething close to following would do: (Inertia*) Aside from taking a perception at face value, it is

    impossible to make a direct rational transition from a mental state with solely mind-to-world direction

    of fit to an action. I will set this complication aside. For first, it isn't clear that taking an experience at

    face value is a mental action. And second, even if it is, this doesn't affect my discussion since, as

    pointed out above, the transition from appreciation to inference can not be modeled on taking a

    perception at face value.

    38 I will generally suppress the qualification or a nearby principle, taking (Intertia) to stand for itself and

    nearby principles.

    direction of fit. I am not following this technical usage here.

    45 Commands, demands, and obligations are not mental. The mental imperative is the impression a

    command, demand, or obligation makes when felt. Maurice Mandelbaum appeals to mental imperatives

    in exploring the phenomenology of moral experience; see (Mandelbaum 1955). Another area where

    philosophers have found it useful to appeal to mental imperatives is in work on the nature of pain. Some
