" It is somehow satisfying to our will to power to think that ‘we’ make the world, that reality itself is but a social construct, alterable at will and subject to future changes as 'we’ see fit. Equally, it seems offensive that there should be an independent reality of brute facts – blind, uncomprehending, indifferent, and utterly unaffected by our concerns. And all of this is part of the general atmosphere that makes antirealist versions of 'poststructuralism’ such as deconstruction seem intellectually acceptable, even exciting. But once you state the claims and arguments of the antirealists out in the open, naked and undisguised, they tend to look fairly ridiculous. "

" When I come home from work and my dog rushes out to greet me, wagging his tail and jumping up and down, why exactly is it that I am so confident that he is conscious and indeed that there is a specific content to his consciousness, he is happy to see me? The usual answer given to this question is that because his behavior is so much like that of a happy person I can infer that he is a happy dog. But that seems to me a mistaken argument. To begin with, happy people do not in general wag their tails and try to lick my hands. Furthermore, and more importantly, someone might easily build a robot dog that would wag its tail and jump up and down without having any inner feelings whatever. What is so special about the real dog? I think the answer is that the basis on which I am confident that my dog is conscious and has a specific content to his consciousness is not simply that his behavior is appropriate, but that I can see that the causal underpinnings of the behavior are relatively similar to mine. He has a brain, a perceptual apparatus, and a bodily structure that are relevantly similar to my own: these are his eyes, these are his ears, this is his skin, there is his mouth. It is not just on the basis of his behavior that I conclude that he is conscious, but rather on the basis of the causal structure that mediates the relation between the input stimulus and the output behavior.
