Abstract.

According to the multiple realization argument, mental states or processes can be realized in diverse and heterogeneous physical systems; and that fact implies that mental states or processes can not be identified with any one particular kind of physical state or process. In particular, mental processes can not be identified with of brain processes. Moreover, the argument provides a general model for the autonomy of the “special” sciences. The multiple realization argument is widely influential. But over the last thirty years it has also faced serious objections. Despite those objections, most philosophers regard that fact of multiple realization and the cogency of the multiple realization argument as obviously correct. Why is that? What is it about the multiple realization argument that makes it so resilient? One reason that the multiple realization argument is deeply intertwined with a view that minds are, in some sense, computational. But I argue that the sense in which minds are computational does not support the conclusion that they are obviously multiply realized. I argue that the sense in which brains compute does not imply that brains implement computational processes that are multiply realizable, and it does not provide a general model for the autonomy of the special sciences.

Computational Theory of Mind

The mind is a lot like a computer — but what if this metaphor was more than just a metaphor? According to the philosopher Andy Clark, human minds aren’t just like computers, human minds are computers! In this video, we’ll get into the consequences of this seemingly radical framework and what it means for cognitive science as a whole.

Radical Study Proposes a Single Cause to Explain Alzheimer’s Disease

A new model of Alzheimer’s disease has been proposed, which could speed up efforts to understand and cure the complex condition – while bringing all manifestations of the condition under one unifying theory.

Researchers from Arizona State University suggest that stress granules – protein and RNA clumps that form around cells in stressful conditions due to genetic and environmental risk factors – are the primary culprit behind the disease.

In their new study, the team reviewed data from multiple health databases and past papers – particularly a 2022 study on Alzheimer’s progression – to identify widespread changes in gene expression that come with it.
