How to Create a Mind: The Secret of Human Thought Revealed

by Ray Kurzweil

If we were to “read” the mind of someone and peer at exactly what is going on in her neocortex, it would be very difficult to interpret her memories, whether we were to take a look at patterns that are simply stored in the neocortex waiting to be triggered or those that have been triggered and are currently being experienced as active thoughts. What we would “see” is the simultaneous activation of millions of pattern recognizers. A hundredth of a second later, we would see a different set of a comparable number of activated pattern recognizers. Each such pattern would be a list of other patterns, and each of those patterns would be a list of other patterns, and so on until we reached the most elementary simple patterns at the lowest level. It would be extremely difficult to interpret what these higher-level patterns meant without actually copying all of the information at every level into our own cortex. Thus each pattern in our neocortex is meaningful only in light of all the information carried in the levels below it. Moreover, other patterns at the same level and at higher levels are also relevant in interpreting a particular pattern because they provide context. True mind reading, therefore, would necessitate not just detecting the activations of the relevant axons in a person’s brain, but examining essentially her entire neocortex with all of its memories to understand these activations.
