Philosophy of Mind
(In the context of neural networks) Philosophy of mind is a branch of modern analytic philosophy that studies the nature of the mind, mental events, mental functions, mental properties, consciousness and their relationship to the physical body, particularly the brain. When using advanced technologies like natural language processing you are moving towards a utility of neural networks. Philosophy of Mind deals with the problems of Externalism and Internalism as far as where mind is "located." This relates to important topics in computer science and neurobiology such as Artificial Intelligence.
