How to Build a Mind: Toward Machines with Imagination (Maps of the Mind)

Neatly illustrates how the field of artificial intelligence has mostly been leaping from enthusiasm to enthusiasm without any deep theoretical consideration of human brains or human consciousness.... Written with warm amusement., The Guardian (London)

A worthy trip for anybody who's wondered... just how the brain does it. -- Carl T. Hall, San Francisco Chronicle

This far-ranging book should interest readers at varying levels, from engineers and computer scientists to science fiction and psychology buffs. -- Hilary Burton, Lawrence Livermore National Lab, California, Library Journal

Igor Aleksander has spent most of his life in the frustrating attempt to develop intelligent machines. In doing so, he has been at the forefront of the Artificial Intelligence community for over four decades. How to Build a Mind is simultaneously a history of AI and an intellectual biography. Since designing thinking machines requires not just the ability to write computer programs but also an understanding of what we mean by 'consciousness,' 'mind,' and 'intelligence,' How to Build a Mind also takes up an inquiry into the history of philosophical explanations of those terms, from Miletus to Ludwig Wittgenstein., Tech Directions

Igor Aleksander heads a major British team that has applied engineering principles to the understanding of the human brain and has built several pioneering machines, culminating in MAGNUS, which he calls a machine with imagination. When he asks it (in words) to produce an image of a banana that is blue with red spots, the image appears on the screen in seconds.

The idea of such an apparently imaginative, even conscious, machine seems heretical, and its advocates are often accused of sensationalism, arrogance, or philosophical ignorance. Part of the problem, according to Aleksander, is that consciousness remains ill defined.

Interweaving anecdotes from his own life and research with imagined dialogues between historical figures -- including Descartes, Locke, Hume, Kant, Wittgenstein, Francis Crick, and Steven Pinker -- Aleksander leads readers toward an understanding of consciousness. He shows not only how the latest work with artificial neural systems suggests that an artificial form of consciousness is possible but also that its design would clarify many of the puzzles surrounding the murky concept of consciousness itself. How to Build a Mind also examines the presentation of "self" in robots, the learning of language, and the nature of emotion, will, instinct, and feelings.
