They rely on their syntax (the initial agreed-upon "grammar") and not their semantics (the constructed "grammar" agreed upon by a culture). A good example of this is apple (the fruit) and apple (the electronics company), both of which have the same syntax but can be used in two very different ways. He states that if a computer thinks with algorithms like this and the computational theory of mind is such, there is no reason why a computer cannot have the same kind of thinking as us. His test called the “Imitation Game” involved having a person, a machine and a human interrogator in three separate rooms. The questioner must ask all written questions, to determine which person is actually a person. If the computer convinces the interrogator that it is a person, Turing insists, does that mean that computers are as intelligent as humans? Although no computer has yet passed the test, Turing believes that the fact that they can come close and will one day be able to mean that they have the ability to think like us. John Searle's countertheory to the Turing test is also very well recognized. thought experiment called the Chinese Room. He finds himself in a room with a manual that tells him how to respond to words or phrases that are passed to him on a piece of paper under a door. He doesn't speak Chinese but, using the manual, he can think of responsive phrases to say to a person on the other end that make it sound like he speaks perfect Chinese. He says he does this by using the manual “to manipulate symbols and numbers (just like a computer does).”
