IntentionalityIntentionality is the power of minds to be about something: to represent or to stand for things, properties and states of affairs. Intentionality is primarily ascribed to mental states, like perceptions, beliefs or desires, which is why it has been regarded as the characteristic mark of the mental by many philosophers. A central issue for theories of intentionality has been the problem of intentional inexistence: to determine the ontological status of the entities which are the objects of intentional states.
Direct and indirect realismIn the philosophy of perception and philosophy of mind, direct or naïve realism, as opposed to indirect or representational realism, are differing models that describe the nature of conscious experiences; out of the metaphysical question of whether the world we see around us is the real world itself or merely an internal perceptual copy of that world generated by our conscious experience. Indirect realism is broadly equivalent to the scientific view of perception that subjects do not experience the external world as it really is, but perceive it through the lens of a conceptual framework.
Multiple realizabilityMultiple realizability, in the philosophy of mind, is the thesis that the same mental property, state, or event can be implemented by different physical properties, states, or events. Philosophers of mind have used multiple realizability to argue that mental states are not the same as — and cannot be reduced to — physical states. They have also used it to defend many versions of functionalism, especially machine-state functionalism. In recent years, however, multiple realizability has been used to attack functionalism, the theory that it was originally used to defend.
Biological naturalismBiological naturalism is a theory about, among other things, the relationship between consciousness and body (i.e. brain), and hence an approach to the mind–body problem. It was first proposed by the philosopher John Searle in 1980 and is defined by two main theses: 1) all mental phenomena, ranging from pains, tickles, and itches to the most abstruse thoughts, are caused by lower-level neurobiological processes in the brain; and 2) mental phenomena are higher-level features of the brain.
ExternalismExternalism is a group of positions in the philosophy of mind which argues that the conscious mind is not only the result of what is going on inside the nervous system (or the brain), but also what occurs or exists outside the subject. It is contrasted with internalism which holds that the mind emerges from neural activity alone. Externalism is a belief that the mind is not just the brain or functions of the brain. There are different versions of externalism based on different beliefs about what the mind is taken to be.
Modularity of mindModularity of mind is the notion that a mind may, at least in part, be composed of innate neural structures or mental modules which have distinct, established, and evolutionarily developed functions. However, different definitions of "module" have been proposed by different authors. According to Jerry Fodor, the author of Modularity of Mind, a system can be considered 'modular' if its functions are made of multiple dimensions or units to some degree. One example of modularity in the mind is binding.
Origin of speechThe origin of speech is a topic that has faced consistent problems in explaining how human language evolved. The topic differs from the origin of language because language is not necessarily spoken; it could equally be written or signed. Language is a fundamental aspect of human communication and plays a vital role in our everyday lives. It allows us to convey thoughts, emotions, and ideas, enabling us to connect with others and shape our collective reality.
Colin McGinnColin McGinn (born 10 March 1950) is a British philosopher. He has held teaching posts and professorships at University College London, the University of Oxford, Rutgers University, and the University of Miami. McGinn is best known for his work in philosophy of mind, and in particular for what is known as new mysterianism, the idea that the human mind is not equipped to solve the problem of consciousness.
