A Fit­ting De­f­i­n­i­tion of Epis­temic Emo­tions
(forth­com­ing) Philo­soph­i­cal Quar­ter­ly
with Juan S. Piñeros Glass­cock
pdf |
Ex­tant at­tempts at defin­ing a cat­e­go­ry of epis­temic emo­tions are in­ad­e­quate. We pro­pose an al­ter­na­tive, ac­cord­ing to which what makes an emo­tion type epis­temic is its fit­ting­ness con­di­tions.

Con­cep­tu­al Lim­i­ta­tions, Puz­zle­ment, and Epis­temic Dilem­mas
(forth­com­ing) Philo­soph­i­cal Stud­ies
pdf |
I show how con­cep­tu­al lim­i­ta­tions could lead to epis­temic dilem­mas and how an epis­temic dilem­mist can ap­peal to un­avoid­able puz­zle­ment as a sign of dilem­mas in the same way that moral dilem­mists ap­peal to un­avoid­able guilt.

Don’t Trust Fodor’s Guide in Monte Car­lo:

Learn­ing Con­cepts by Hy­poth­e­sis Test­ing With­out Cir­cu­lar­i­ty

(2023) Mind & Lan­guage
pdf | of­fi­cial ver­sion |
Ac­tu­al­ly 𝜑-ing doesn’t im­ply abil­i­ty to 𝜑 when the right kind of ran­dom­ness is in­volved. This kind of ran­dom­ness is in­volved in the sam­pling meth­ods that many cog­ni­tive sci­en­tists think we ac­tu­al­ly use in learn­ing. So, con­tra Fodor, we can learn con­cepts by hy­poth­e­sis test­ing with­out cir­cu­lar­i­ty.
Bad Con­cepts, Bi­lat­er­al Con­tents
(2022) Ergo
pdf | of­fi­cial ver­sion | slides |
We can take con­cepts to be in­con­sis­tent with­out go­ing in for in­fer­en­tial­ism. Bi­lat­er­al­ism is all that’s need­ed. But a puz­zle re­mains: what’s de­fec­tive about in­con­sis­tent con­cepts?
Off­set­ting Harm
(2022) Ox­ford Stud­ies in Nor­ma­tive Ethics, Vol­ume 12
pdf | of­fi­cial ver­sion | slides |
To make sense of the per­mis­si­bil­i­ty of off­set­ting, the stan­dard de­on­to­log­i­cal con­straint against do­ing harm should be re­placed with one against un­off­set harm in­creas­es.

Stu­pe­fy­ing
(2022) Philoso­phers’ Im­print
pdf | of­fi­cial ver­sion |
S stu­pe­fies A when A ac­cepts S’s as­ser­tion with­out un­der­stand­ing it. I ar­gue stu­pe­fy­ing is an im­por­tant means both for good (co­op­er­a­tive, joint­ly ra­tio­nal in­quiry) and bad (ma­nip­u­la­tion) that cur­rent mod­els of con­ver­sa­tion do not ac­count for.

A Plea for In­ex­act Truth­mak­ing
(2020) Lin­guis­tics and Phi­los­o­phy
pdf | of­fi­cial ver­sion | poster |
Con­tra Kit Fine, truth­mak­er se­man­tics should de­fine ex­act truth­mak­ing in terms of in­ex­act truth­mak­ing, rather than vice ver­sa.

Coun­ter­fac­tu­al Don­keys Don’t Get High
(2018) Pro­ceed­ings of Sinn und Be­deu­tung 22
pdf | of­fi­cial ver­sion | slides |
Uni­ver­sal en­tail­ments of coun­ter­fac­tu­al don­key sen­tences aren’t as uni­ver­sal as as­sumed in the lit­er­a­ture. This makes de­riv­ing them from a con­tex­tu­al­ly pro­vid­ed sim­i­lar­i­ty or­der­ing more at­trac­tive than de­riv­ing them from a se­man­ti­cal­ly-en­cod­ed as­sign­ment sen­si­tiv­i­ty.

Coun­ter­fac­tu­al Dou­ble Lives
(2017) Pro­ceed­ings of the 21st Am­s­ter­dam Col­lo­qui­um
pdf | of­fi­cial ver­sion | slides |
Coun­teri­den­ti­cals (“If I were you...”) and re­lat­ed more or­di­nary coun­ter­fac­tu­als show we should re­ject the Krip­ke-Ka­plan or­tho­doxy about in­dex­i­cals. Lewisian coun­ter­part the­o­ry looks like the way to go.
