John Searle's Can Computers Think?

1300 Words3 Pages

At some point in our lives, we have wondered about the possibility of a computer being able to think. John Searle addresses this issue in his paper, “Can Computers Think?”, where he argues that computers cannot think because they are directed by formal information. This means that the information presented is only syntax with no semantics behind it. In this paper, I will elaborate more on Searle’s position and reasoning whilst critiquing his argument by saying that it is possible to derive semantics from syntax. Finally, I will analyze the significance of my criticism and present a possible response from Searle to defend his argument.
In “Can Computers Think?”, Searle argues that computers are unable to think like humans can. He argues this …show more content…

Computers are machines that take syntactical information only and then function based on a program made from syntactical information. They cannot change the function of that program unless formally stated to through more information. That is inherently different from a human mind, in that a computer never takes semantic information into account when it comes to its programming. Searle’s formal argument thus amounts to that brains cause minds. Semantics cannot be derived from syntax alone. Computers are defined by a formal structure, in other words, a syntactical structure. Finally, minds have semantic content. The argument then concludes that the way the mind functions in the brain cannot be likened to running a program in a computer, and programs themselves are insufficient to give a system thought. (Searle, p.682) In conclusion, a computer cannot think and the view of strong AI is false. Further evidence for this argument is provided in Searle’s Chinese Room thought-experiment. The Chinese Room states that I, who does not know Chinese, am locked in a room that has several baskets filled with Chinese symbols. Also in that room is a rulebook that specifies the various manipulations of the symbols purely based on their syntax, not their semantics. For example, a rule might say move the squiggly …show more content…

He would say that it is still impossible for a computer to derive semantic information from merely syntax because the two things, according to him, are mutually exclusive when separate. It is impossible to gain any semantic information from syntax alone, which would mean that even if a robot was interacting with the world, the computer inside the robot is only getting syntactical information and processes it in syntactical terms only. It is also important to note, in the words of Searle, that a computer’s “operations have to be defined syntactically, whereas consciousness, thoughts, feelings, emotions, and all the rest of it involve more than syntax.” (Searle, p.681) Therefore, even though a robot would be able to simulate being a human, it cannot actually be a human. I then believe, with that evidence, Searle would conclude that the Robot reply would not satisfy the conditions needed for a computer to be able to
