The human brain Today it is common to compare the human brain to a computer, and a human mind to a program running on a computer. Once seen as just a poetic metaphor, this viewpoint is now supported by most philosophers of human consciousness and most researchers in Machine Intelligence. If we take this view literally, then as we can ask how many gigabytes of RAM a PC has we should be able to ask how many gigabytes of memory the human brain has. Machine intelligence researchers have used a digital computer as a model of the human mind in two ways. Most obviously, the computer has been used as a tool, on which simulations of thinking-as-programs are developed and tested. Less obvious, but of great significance, is the use of the computer as a conceptual model of the human mind. This essay traces the sources of this machine-modeled conception of cognition in a great variety of social institutions and everyday experiences, treating them as "cultural models" which have contributed to the naturalness of the mind-as-machine paradigm for many people, the roots of these models antedate the actual and cognitive landscape of modernity. The essay concludes with a consideration of some of the cognitive consequences of this extension of machine logic into modern life, and proposes an important distinction between information processing models of thought and meaning-making in how human cognition is conceptualized.
