But we use artificial things like computers and math to extend the brain." It doesn't matter how much information we process through our direct senses or through artificial or indirect sources of information. In the end, it is in our brain that we use to process and integrate all the data we have taken in. When she says that Reason is your only source of knowledge, she is referring to after the sensory input (the smells, the sounds, the touch, and the information from 52 websites on your new Nexus 5 smart phone). Because until the information is in your brain, it is irrelevant to what you think. And how is that information to become meaningful or useful to you if it is not processed intelligently? People who cannot process information intelligently cannot survive on their own. They need to be looked after by others. Look how the three thread monkeys look after each other? By fawning over one another and avoiding all sense of honesty and decency, they create a powerful form of sludge. But is that any way to live a life? You can take all the information in the world from the largest computer. And you can take the sonar 'hearing' of a bat or the hearing of an owl, and the eyes of an eagle, or the thermal vision of a snake, etc. etc. But this information is pretty much meaningless to you in your nose? It needs to be in your brain to be useful. Why is that? Because the human brain can integrate that information and make sense of it to improve the probability of life and the quality of life. Living solely by instinct is brutish...and necessarily ignores almost all the information you were speaking of as being out there.
