Semantic shift, also known as semantic change, is the process by which the meaning of a word or phrase changes over time. This can happen for a variety of reasons, including changes in societal norms and values, technological advancements, and shifts in the way language is used and understood.
One common type of semantic shift is the process of broadening or narrowing. This occurs when a word's meaning becomes either more specific or more general over time. For example, the word "nice" used to mean "foolish or stupid," but over time its meaning has broadened to include positive connotations such as "kind" or "pleasing." On the other hand, the word "gay" used to mean "happy" or "carefree," but its meaning has narrowed to specifically refer to sexual orientation.
Another type of semantic shift is the process of amelioration or pejoration. This occurs when a word's meaning becomes either more positive or more negative over time. For example, the word "savage" used to mean "wild" or "uncivilized," but its meaning has become more negative and is now often used to describe someone as cruel or vicious. On the other hand, the word "awesome" used to mean "inspiring fear or admiration," but its meaning has become more positive and is now often used to describe something as impressive or remarkable.
Semantic shift can also be caused by shifts in the way language is used and understood. For instance, the word "cool" was originally used to describe temperature, but it has since taken on a variety of slang meanings, including "calm" or "unconcerned," and " fashionable" or "trendy." This type of semantic shift is often driven by the way language is used in popular culture, such as music and media.
Semantic shift can have a significant impact on the way we communicate and understand language. It is important to be aware of these changes in meaning to ensure clear and effective communication. Additionally, understanding the history and evolution of words can provide insight into the values and cultural norms of different periods in history.
In conclusion, semantic shift is the process by which the meaning of a word or phrase changes over time. It can be caused by societal changes, technological advancements, and shifts in the way language is used and understood. Understanding these changes can help us communicate effectively and gain insight into the values and cultural norms of different periods in history.
John Searle
The answers to the claim on computer simulations matching the human brain's intentionality sufficiency will be based on John Searle's counter-arguments and accompanying philosophical perceptions Searle, 1980. First of all in the paper Searle differentiates between different types of artificial intelligence: weak AI, which is just a helping tool in study of the mind, and strong AI, which is considered to be appropriately designed computer able to perform cognitive operations itself. Similar behaviors and appearances play the majority descriptive role of the robot and the indistinguishable large range human behaviors. From the above example, we observe that the computer and the program provide insufficient conditions to understand since both function without understanding. This creates a biological problem, beyond the Other Minds problem noted by early critics of the CR argument. It is such self-representation that is at the heart of consciousness. So, according to the Strong AI thesis, there is some description C of a type of computational process such that if C is true of any machine, then that machine has mental states e.
A weaker thesis asserts that a tight causal connection between P and the behaviour is sufficient for M x. A somewhat different case arises when a physical representation of the program P is stored in the memory of the computer and directly interpreted either by hardware or software. However, the Al looks at the board differently than we do. This larger point is addressed in the Syntax and Semantics section below. Such a robot would ascribe to intentions of the system and ensure that people do not die. Whether it does or not depends on what concepts are, see section 5.
Could there be artifical intelligence (AI) in what Searle calls the strong sense?
Journal for the Theory of Social Behaviour. Different answers are possible, for instance, that ALL are, that SOME are, and that NONE are. I, starting or differentiating a formal program in place with the required inputs and expected outputs is a sufficient condition which must be, constituted and have intentionality. Turing 1950 proposed what is now known as the Turing Test: if a computer could pass for human in on-line chat, it should be counted as intelligent. If all you see is the resulting sequence of moves displayed on a chess board outside the room, you might think that someone in the room knows how to play chess very well. He then suggests that the reason why mere instantiation of a program cannot produce mentality is that mental processes involve intentionality, and only an underlying machine with the right causal powers, e.
How can one refute John Searle's "syntax is not semantics" argument against strong AI?
In the 1990s, Searle began to use considerations related to these to argue that computational views are not just false, but lack a clear sense. Thinking, Fast and Slow. The third reason, as mentioned by John Searle, suggests that the different mental states and the events occur literally after the operations of the brain. These considerations lead to a requirement for intelligent systems to have a complex computational architecture which allows different processes to run asynchronously, for instance, plan-execution, perceptual monitors, reasoning and decision-making. Cole suggests the intuitions of implementing systems are not to be trusted. As most of these possibilities will not have occurred to either player, Searle thinks the Background is itself unconscious as well as nonintentional.

The second group of critics researches the way how meaningless symbols can become meaningful. So, as it was already mentioned the first argument was concerned with the mind source. That robot would understand. It would merely appear to be so, but would still not be able to play a dependable role in social relationships e. An AI enthusiast may reply: 240 1. Searle would be manipulating these symbols and have no idea what's going on with the robot III.
Consider the game of chess. For instance, a robot whose planning processes were subject to the quirks of an intelligent sub-agent interpreting its planning programs, might often form plans which undermined its own goals. Searle's claims are based on philosophical work by Roger Schank and Yale, who argue that machines simulate human brains by understanding stories and giving answers. Pinker ends his discussion by citing a science fiction story in which Aliens, anatomically quite unlike humans, cannot believe that humans think when they discover that our heads are filled with meat. Sloman, 'What enables a machine to understand? Searle considered the omission of parasitic discourse forms to be justified by the narrow scope of Austin's inquiry.
But these critics hold that a variation on the computer system could understand. Structural conditions for understanding might be satisfied, but not the functional conditions, just as an accelerator pedal detached from a car cannot produce any acceleration. Sloman, The computer revolution in philosophy: Philosophy, Science and models of mind, Harvester Press, 1978. He makes it clear that on the view he is attacking, it makes no difference exactly how the behaviour is produced, as long as it instantiates the right program: as long as it has the right formal properties, it is supposed to suffice for the existence of mentality. A hypnotised person would be an interesting intermediate case. For Searle, Searle also introduces a technical term the Background, Background the set of abilities, capacities, tendencies, and dispositions that humans have that are not themselves intentional states but that generate appropriate such states on demand. He argued that even if we assume that we had a computer program that acted exactly like a human mind, there would still be a difficult philosophical question that needed to be answered.

There is reproduction process, and hence this explains the mental phenomena. In answering the questions whether both men ate humbuggers, the computer gives the same response with that of human beings. The whole robot behavior covers all the human behavior. These rules are purely syntactic — they are applied to strings of symbols solely in virtue of their syntax or form. Syntax is not identical with nor sufficient by itself for semantics. Searle responded to this objection by stating that if the individual is not capable of understanding the semantics, then the system is incapable as well because he is apart of the system.
