We conclude the symposium on inner speech with a summary of Daniel Gregory's recent work: 'Inner speech and sign languages.' Make sure to check out the blog for thoughts by Gregory and others!

philosophyofbrains.comDaniel Gregory: Signed Inner SpeechSigned Inner Speech Daniel Gregory ***What follows summarizes some ideas in my recent paper, ‘Inner speech and sign languages’ (Gregory 2026).*** When native speakers of voiced languages (such as English, Mandarin or Hindi) think about inner speech, they naturally tend to think of a mental state with an auditory phenomenology—something like an internal correlate of speech spoken aloud. But what about the inner speech of people whose native language is a sign language (such as American Sign Language, Indo-Pakistani Sign Language or Russian Sign Language)?

In this next addition to our inner speech symposium, Marta Jorba explores the puzzle of self talk. We invite you to tune in!

philosophyofbrains.comMarta Jorba: Do we know what we think before saying it to ourselves?Do we know what we think before saying it to ourselves? Marta Jorba  Pompeu Fabra University LOGOS Research Group Self-talk, or talking to oneself, seems to present a puzzle. If, for instance, I tell myself, “I think I will read the Odyssey this summer”, it seems that, in order to have the intention to communicate this thought to myself, I must already know what I think.

This is a substantial oversight. My post is a rallying cry: Inner speech shouldn’t be relegated to the periphery of our theorizing about language and its uses; it should be at the center.

Yoonhee Jung Ned Block (2010; 2015) challenges representationalism on the grounds that covert attention—the allocation of attention without eye movement—can alter the phenomenal character of perceptual experience without changing its representational content.[1] He considers an experiment developed by Carrasco and her colleagues in which subjects viewed two Gabor patches presented simultaneously in the periphery while maintaining fixation of their eyes on a central point (see Figure 1).

It is relevant to Sprevak and Fallon’s PhiMiSci Special Issue on Representation in the Neurosciences and AI because conditions on AI agency are often articulated in representational terms. Approaches to AI agency can be instrumentalist, for example when being an agent is understood in terms of representing goals and means to achieving goals, where representation is in turn understood to be a matter of displaying a certain pattern of behaviour.

philosophyofbrains.comCaitlin Mace & Adina L. Roskies:  Vehicle realism, content pragmatism – Uneasy bedfellows Title: Vehicle realism, content pragmatism: Uneasy bedfellows Caitlin Mace and Adina L. Roskies  Frances Egan’s (2025) “Deflating Mental Representation” poses an interesting challenge to both realists and fictionalists about mental representation. In the book she argues for a pragmatic view of representational content and realism about representational vehicles.  The book as a whole is a deflationary take on the primary ways in which the concept of representation enters into cognitive science: in scientific theorizing about the brain, in folk psychological discourse, and in perception.

Computational individuation, he claims, is subject to indeterminacy, and at least in some cases the indeterminacy is resolved by appeal to content. If content is a gloss, as I argue, then according to Shagrir computational characterization is partly a gloss too.   Shagrir deploys an example to make the case for computational indeterminacy.

While the more contentious thesis concerns content, my focus is on Egan's conception of computation, which has shaped much of the ongoing debate on physical computation in recent decades.
