Why Can’t Science Explain Consciousness?

by Bill Pratt

It is not uncommon these days to hear something like the following: “Science has explained just about everything else in the world, so it is inevitable that science will explain the mind and consciousness.” This kind of comment always makes me roll my eyes because the people who make this comment are making a colossal error, but an error that can be hard to see.

Philosopher Ed Feser gives a brilliant analogy that makes the error more obvious. He calls it the “lump under the rug” fallacy.

Suppose the wood floors of your house are filthy and that the dirt is pretty evenly spread throughout the house.  Suppose also that there is a rug in one of the hallways.  You thoroughly sweep out one of the bedrooms and form a nice little pile of dirt at the doorway.  It occurs to you that you could effectively “get rid” of this pile by sweeping it under the nearby rug in the hallway, so you do so.  The lump under the rug thereby formed is barely noticeable, so you are pleased.

You proceed to sweep the rest of the bedrooms, the bathroom, the kitchen, etc., and in each case you sweep the resulting piles under the same rug.  When you’re done, however, the lump under the rug has become quite large and something of an eyesore.  Someone asks you how you are going to get rid of it.  “Easy!” you answer.  “The same way I got rid of the dirt everywhere else!  After all, the ‘sweep it under the rug’ method has worked everywhere else in the house.  How could this little rug in the hallway be the one place where it wouldn’t work?  What are the odds of that?”

What is wrong with using the “sweep it under the rug” method to get rid of the dirt under the rug?
