What does it Mean? The "Brain In a Jar" discussion is a common philosophical debate. When Rene Descartes contemplated the existence of an evil demon he considered the "Brain in a Vat" scenario. The premise is that a mad scientist removes your brain, and places it into a vat of liquid to keep it alive and active. Recently the theme was explored in the popular series "The Matrix" and also "Ex Machina".For the sake of argument, suppose that the mad scientist was able to hook your brain up to a computer sending signals in the way the brain normally receives them. Thus, creating a false reality to fool you into believing that you are still walking around in your body.Given the setup, the question is: how do you know right now that you are not a brain in a jar? One conclusion: it is impossible (for the brain itself) to tell whether it is a brain in a vat or a brain in a skull.Wait..... it couldn't happen, anyway.According to computer scientist Ralph Merkle, your brain is material and governed by the laws of physics. Those laws can be simulated by computers. So too can your brain. Really? Yes, the brain's network of connectivity is vast and extremely complex. However, we can put a number on how many bits would be necessary to encode it. By Merkle's calculations, uploading the contents of a brain will need a computer memory of about 1018 bits, performing around 1016 logic operations per second. And that will be possible soon.So, are you just a brain in a jar? Makes you wonder. And that's why it is a nice "pop" of moxie.Your satisfaction is guaranteed or we will offer a full refund.
