The only feelings we can feel are our own. When it comes to the feelings of others, we can only infer them, based on their behavior ? unless they tell us. This is the ?other-minds problem.?

Within our own species, thanks to language, the other-minds problem arises only for states in which people cannot speak (infancy, aphasia, sleep, anaesthesia, coma). Our species also has a uniquely powerful empathic or ?mind-reading? capacity: We can (sometimes) perceive from the behavior of others when they are in states like our own. Our inferences have also been systematized and operationalized in biobehavioral science and supplemented by cognitive neuroimagery. Together, these make the other-minds problem within our own species a relatively minor one.

But we cohabit the planet with other species, most of them very different from our own, and none of them able to talk. Inferring whether and what they feel is important not only for scientific but also for ethical reasons, because where feelings are felt, they can also be hurt.

Animal Sentience [ASent] is a new international, interdisciplinary journal devoted to the other-minds problem across species. As animals are at long last beginning to be accorded legal status and protection as sentient beings, ASent will explore in depth what, how and why organisms feel. Individual ?target articles? (and sometimes précis of books) addressing different species? sentient and cognitive capacities will each be accorded ?open peer commentary,? consisting of multiple shorter articles, both invited and freely submitted ones, by specialists from many disciplines, each elaborating, applying, supplementing or criticizing the content of the target article, along with responses from the target author(s).

The members of the nonhuman species under discussion will not be able to join in the conversation, but their spokesmen and advocates, the specialists who know them best, will. The inaugural issue launches with the all-important question (for fish) of whether fish can feel pain.

ASent is a publication of the Humane Society Institute for Science and Policy (HSISP). Based in Washington DC, HSISP?s mandate is to advance the application of scientific and technical analysis and expertise to animal welfare issues and policy questions worldwide. The HSISP is an affiliate of The Humane Society of the United States, the world?s largest animal protection organization.

ASent is a peer-reviewed, open-access journal. Thanks to HSISP sponsorship, ASent need not charge either publication fees to authors or subscription fees to readers.

Authors’ opinions do not necessarily reflect those of the publisher or editors.

The table of contents of the inaugural issue of ASent follow below. Commentaries by scientists, scholars, practitioners, jurists and policy-makers are invited on any of the target articles (in bold); continuing commentary is also invited on the commentaries and responses. And of course the journal now calls for the submission of target articles. All target articles are peer-reviewed and all commentaries are editorially reviewed. Open peer commentary is intended particularly for new target articles written specifically for ASent, but updated versions of articles that have appeared elsewhere may also be eligible for publication and open peer commentary.

(Open peer commentary is modelled on the journal Behavioral and Brain Sciences (BBS), of which the editor-in-chief of ASent was also the founder and editor-in-chief for 20 years.)
