Are you familiar with that little half height floor in Being John Malkovich? You are pretty much there, but for the internet. In all seriousness, interesting article. Quoting you, quoting Newton: I don't think we can point to anything unlike this, correct?: up/down are sensations of gravity, temperature is a sensation of molecular motion, etc. Random thought: I can't think of any sensations that result from multiple physical phenomenon. Color and intensity, frequency and amplitude, perhaps... but nor from 'green and hot' or 'down and loud'. I wonder if any intelligence combines two unique phenomenon into a useful sensation.No, not a lurker, in fact I'm not really sure where I am yet!
Newton also said something very strange: he said that "the rays to speak properly are not coloured". By this he meant that a colour is really a sensation of the mind resulting from light, just like a sound is a sensation of the mind resulting from physical vibrations of the air.
