Philosophy has a lot of theories about knowledge. Whether we can know anything, how much we can know, what we need to be able to say that we know. So can we know anything?
I’m no skeptic (in the philosophical sense, not the atheistic sense), so I’d say yes. We can know things. But our knowledge is probabilistic. I don’t think we can know anything with 100% certainty. But we can certainly say that we “know” to a degree that makes it unlikely that we are wrong.
For example, I’d say that I know that Stephen Harper is the Prime Minister of Canada. This is a simple fact for those of us in Canada, and I’d say that I’m 99.9% certain that I know that this fact is true. But there is still the chance that I’m wrong. Perhaps I’m simply dreaming that Harper is Prime Minister, or maybe I’m a brain in a vat. Both cases are extremely unlikely to the point where I’m confident in saying that I know that Stephen Harper is Prime Minister.
But, like I said before, there are many theories. So, can we know anything?
