Relationism, Rationalism, and the Teleological Account of Belief

Ema Sullivan-Bissett
In my last blog post I wrote about mine and Paul Noordhof’s work on relationist accounts of experience and delusional belief formation. The conclusion from that post was that the relationist who denies phenomenal character to hallucinatory experience could not accept any empiricist account (an account which gives anomalous experience a role in the explanation of delusion formation) of what we called ‘positive delusions’ (delusions involving hallucinatory experience). This meant that the relationist must adopt a rationalist account of delusion formation, an account which refuses ‘to ground the delusion in an abnormal experience’ (Bayne and Pacherie 2004: 81).

Thought Insertion and the Adaptive Role of Delusions

Pablo López-Silva
I am a current PhD student at the University of Manchester Philosophy Department (Mind Group). I’m working on different philosophical problems raised by schizophrenia under the supervision of Dr Joel Smith and Prof Tim Bayne.

I became interested in the philosophical discussions surrounding schizophrenia while I was taking my clinical courses for my psychology professional degree in Chile. While attending some patients, I realized that delusions seemed to have a strong adaptive function. Although this is a matter that needs further argumentation, I think that systematic research on the structure of certain delusions can facilitate better understandings of their role (Roberts, 1992) and, quite importantly, to improve therapeutic intervention (Guidano, 1991). An example of this can be offered by looking at the structure of thought insertion, an abnormal conscious experience commonly regarded as suggestive of schizophrenia (Mullins & Spence, 2003).
