Eliminative Materialism (Stanford Encyclopedia of Philosophy)

In principle, anyone denying the existence of some type of thing is an eliminativist with regard to that type of thing. Thus, there have been a number of eliminativists about different aspects of human nature in the history of philosophy. For example, hard determinists like Holbach (1770) are eliminativists with regard to free will because they claim there is no dimension of human psychology that corresponds to our commonsense notion of freedom. Similarly, by denying that there is an ego or persisting subject of experience, Hume (1739) was arguably an eliminativist about the self. Reductive materialists can be viewed as eliminativists with respect to an immaterial soul.

Nevertheless, contemporary eliminative materialism—the sort of eliminativism that denies the existence of specific types of mental states—is a relatively new theory with a very short history. The term was first introduced by James Cornman in a 1968 article entitled “On the Elimination of ‘Sensations’ and Sensations” (Cornman, 1968). However, the basic idea goes back at least as far as C.D. Broad’s classic, The Mind and its Place in Nature (Broad, 1925). Here Broad discusses, and quickly rejects, a type of “pure materialism” that treats mental states as attributes that apply to nothing in the world (pp. 607–611). Like many future writers (see section 4.1 below), Broad argued that such a view is self-contradictory since it (presumably) presupposes the reality of misjudgments which are themselves a type of mental state.

Apart from Broad’s discussion, the main roots of eliminative materialism can be found in the writings of a number of mid-20th century philosophers, most notably Wilfred Sellars, W.V.O. Quine, Paul Feyerabend, and Richard Rorty. In his important 1956 article, “Empiricism and the Philosophy of Mind”, Sellars introduced the idea that our conception of mentality may be derived not from direct access to the inner workings of our own minds, but instead from a primitive theoretical framework that we inherit from our culture. While Sellars himself regarded this theoretical framework as empirically correct, his claim that our conception of the mind is theory-based, and at least in principle falsifiable, would be influential to later supporters of eliminativism.

Memories of childhood trauma remain stable over time but change more often in children than adults

Traumatic memories of childhood maltreatment typically remain consistent over time, according to a major new study led by King’s College London and published in Nature Mental Health. The paper focuses on traumatic memories of childhood maltreatment, which could include emotional, physical or sexual abuse, or neglect. While memories of childhood maltreatment remain consistent, memories of childhood trauma reported in childhood are significantly less consistent over time than those reported in adulthood.

This research finding suggests there may be a window in childhood when traumatic memories are most open to change, and when therapeutic intervention could have the greatest long-term impact.

The research draws on data from nearly 40,000 people across 49 studies, with an average time between assessments of about two and a half years. It found that, overall, people’s accounts of childhood maltreatment are more consistent over time than is often assumed, refuting a widespread view that memories of abuse and neglect are inherently unreliable. This finding has direct relevance for how courts, social care professionals and clinicians interpret what children and adults tell them about their experiences.

An artificial neuromorphic interface for auditory restoration

Hearing loss affects millions of people, requiring technology to repair their auditory pathway. A biohybrid interface is developed that combines a self-powered acoustic device and an artificial auditory neural circuit, enabling restoration of auditory function in a rabbit model of hearing impairment.
