ABSTRACT
I think that we all know many things. I believe I know many facts about my immediate surroundings, much about myself, something about the past, and a little about the future. I believe that we also have scientific knowledge, that we know some general moral truths, and that it is certainly possible that we know some religious truths. But there are reasons to doubt all of this. There are reasons to think that at best we know very little, perhaps just self-evident truths, such as that if no vixens are males then no males are vixens, and a few propositions about our present consciousness, such as that I am now thinking about the scope of human knowledge.
