I have already told you: the gathering and processing of sensory data into a coherent image of your surroundings.
I would say "read" again, but at this point, it's fairly obvious that you aren't simply ignoring what I say, but completely failing to understand it.
Reading is not your issue. Your egotistical insistence that your incoherent non-definitions are in any way correct, your labeling of any attempt to tell you that they are wrong as "desperate", your inability to appreciate the inherently pointless and semantic nature of your argument, and your out-of-hand dismissal of perfectly cogent points raised against you all make it very clear what the actual problem is.
You didn't come here to have a discussion. You didn't even come here to make an argument. You came here to preach, and show off something that you think makes you very smart, and you don't give a damn what the actual facts in the case are.
Sorry, Nick. But the dictionary exists, and is not on your side. Neither, come to it, are basic logic, neuroscience, or even semantics, and no amount of your insistence to the contrary will change that.
