What are hard problems?
A problem is “hard” if it requires (or we think it requires) “large” computational resources to solve, and “easy” if it doesn’t. “Large” depends on context but, in most contexts, a problem that can be solved in polynomial time is considered “easy”.
What are the easy problems of consciousness?
The easy problems of consciousness are those that seem directly susceptible to the standard methods of cognitive science, whereby a phenomenon is explained in terms of computational or neural mechanisms. The hard problems are those that seem to resist those methods.
What exactly is the explanatory gap?
In philosophy of mind and consciousness, the explanatory gap is the difficulty that physicalist theories have in explaining how physical properties give rise to the way things feel when they are experienced. It is a term introduced by philosopher Joseph Levine.
What is Physicalist theory?
Physicalism is the thesis that everything is physical, or as contemporary philosophers sometimes put it, that everything supervenes on the physical. The general idea is that the nature of the actual world (i.e. the universe and everything in it) conforms to a certain condition, the condition of being physical.
What does the thesis Physicalism claim?
Physicalism is roughly the metaphysical thesis that claims that the world is fundamentally physical. The term ‘physicalism’ was first introduced by Carnap and Neurath to designate instead a semantic thesis: every sentence describing the mental can be translated into sentences in a physical vocabulary.
Is functionalism a Physicalist theory?
In this sense of physicalism, most functionalists have been physicalists. Further, functionalism can be modified in a physicalistic direction, for example, by requiring that all properties quantified over in a functional definition be physical properties. Type physicalism is often contrasted with token physicalism.
What is property dualism in philosophy?
Property dualism describes a category of positions in the philosophy of mind which hold that, although the world is composed of just one kind of substance—the physical kind—there exist two distinct kinds of properties: physical properties and mental properties.
Who invented materialism?
Democritus
Is Aristotle a materialist?
However, as revealed in his psychological works, Aristotle is no reductive materialist. Instead, he thinks of the body as the matter, and the psyche as the form of each living animal.
What is soul for Aristotle?
A soul, Aristotle says, is “the actuality of a body that has life,” where life means the capacity for self-sustenance, growth, and reproduction. If one regards a living substance as a composite of matter and form, then the soul is the form of a natural—or, as Aristotle sometimes says, organic—body.
What did Aristotle believe?
Aristotle’s philosophy stresses biology, instead of mathematics like Plato. He believed the world was made up of individuals (substances) occurring in fixed natural kinds (species). Each individual has built-in patterns of development, which help it grow toward becoming a fully developed individual of its kind.
What is Aristotle’s theory of justice?
Justice is one of the most important moral and political concepts. Aristotle says justice consists in what is lawful and fair, with fairness involving equitable distributions and the correction of what is inequitable.
