Answer 2

What is the question you are wishing to refute? The brain in a vat is a scenario where a mad scientist has put your brain in a vat and it using a computer to feed it all the sensory data it would normally receive. The idea is to get you to realize that there is nothing you can know in an absolute sense, because all sensory input can be manufactured.

Although it is an interesting mental exercise, in real life we tend to assume certain things about our environment. For example, we assume we are not a brain in a vat and all the sensory input we receive is actually coming in from real phenomenon out there.

While there is nothing to refute the claim that we're a brain in a vat, it doesn't really imply much. Our world, no matter how presented to us is what we consider our world to be, and we act accordingly. In that sense, even if we're a brain in a vat, the information we receive is as real to us as anything else.

Here's a discussion of it in Wikipedia, and a discussion of his Meditations on First Philosophy.
