If that's your argument, though, then you have to accept the well-trod
reductio ad absurdum that Descartes toyed with. It's only a matter of faith that you have feet if you're not looking directly at them, right?
And if that's the case, then you can argue that the only thing we KNOW is what we're looking directly at. Unless, of course, our eyes can deceive us as in the case of mirages, or what we think we see when we're dreaming. We have a sense called proprioception, by which we know our feet are there, and where they are in space; but on the other hand people can get phantom limb syndrome so that sense may not be reliable either.
We all know this argument. But again, I think we have to divest the concept of knowledge from arguments about absolutism -- knowledge is a human thing, it's not absolute. Our ability to know, to understand, to discover, and to prove is finite.
At a more practical level, this becomes less problematic if we are less, you know, philosophical about it. We're social animals. We depend on each other. There is a degree to which knowledge is individual and a degree to which it is shared. You can use the word "faith" to describe it, but I think that's an oversimplification. The difference between faith in some religious belief as opposed to faith in a human chain of knowledge is that we're much more willing to accept all the caveats that come with that chain of knowledge.
If you tell me that Tashkent is the capital of Tajikistan, and I go around telling people that, and one day I discover that it's actually Dushanbe and not Tashkent, this isn't going to rock my world.
