“The central metaphor of these four chapters is that the mind is divided, like a rider on an elephant, and the rider’s job is to serve the elephant. The rider is our conscious reasoning—the stream of words and images of which we are fully aware. The elephant is the other 99 percent of mental processes—the ones that occur outside of awareness but that actually govern most of our behavior.”

“That ability would seem to be at odds with early epiphenomenalism, which according to Huxley is the broad claim that consciousness is “completely without any power… as the steam-whistle which accompanies the work of a locomotive engine is without influence upon its machinery”.

“when I woke in the middle of the night, since I did not know where I was, I did not even understand in the first moment who I was; I had only, in its original simplicity, the sense of existence as it may quiver in the depths of an animal; I was more destitute than a cave dweller; but then the memory—not yet of the place where I was, but of several of those where I had lived and where I might have been—would come to me like help from on high to pull me out of the void from which I could not have got out on my own; I crossed centuries of civilization in one second, and the image confusedly glimpsed of oil lamps, then of wing-collar shirts, gradually recomposed my self’s original features.”

“But let us go further. Consciousness is a much smaller part of our mental life than we are conscious of, because we cannot be conscious of what we are not conscious of. How simple that is to say; how difficult to appreciate! It is like asking a flashlight in a dark room to search around for something that does not have any light shining upon it. The flashlight, since there is light in whatever direction it turns, would have to conclude that there is light everywhere. And so consciousness can seem to pervade all mentality when actually it does not.”
