It is filled with many promising roads that end up nowhere, false starts from the beginning, and genuinely fruitful avenues of inquiry.
Let's start with what appeared to be a promising start and see where it led:
A classic in the field in the Anglo-American sphere of philosophy is Gilbert Ryle's The Concept of Mind (1949) with its famous image of "the ghost in the machine," essentially denying that there is anything else going on in the mind but the physical brain. Arthur Koestler, a briiliant polymath, took the metaphor as the title of his study, The Ghost in the Machine in his 1967 study.
Start with these two references and I will add more as we go on.
The next readings I would recommend for you are related to the philosophy of science, the sociology of knowledge, and Foucault's work on both history and what he called the archaeology of knowledge and the history of madness.
Without these basics, I think you cannot read the current approaches to philosophy of mind without getting lost - and this is a minimal map of the more accessible works.
Daniel Dennett, while sharply disagreeing on some points, acknowledged Nagel’s paper as "the most widely cited and influential thought experiment about consciousness."
