Which is true, we cannot be absolutely certain about the truth of some claim, but we can come close enough to say it is either raining in Quito or not and still be accurate. There is a difference between what is true, and the truth as best as we can arrive at it. That you have parents is difficult to dispute.
If by "absolutely certain" is mean, "infallible" and without the possibility of error, then "to err is human". It is always possible to be mistaken. But that doesn't mean, of course, that we are (in fact) mistaken. When I claim to know, for instance, that Quito is the capital of Ecuador, I am not claiming that it is
impossible that I am mistaken. Rather I am claiming that I am not (actually) mistaken. So that it is no objection to my claim to know to point our that I
might be mistaken, if it is allowed that I am not mistaken. Would it not be silly to say that although it is true that Quito is the capital of Ecuador, I am wrong to claim to know it is because Quito might not be the capital of Ecuador. What difference would it make that Quito
might not be the capital of Ecuador to whether I know that it is, as long as Quito is, in fact, the capital of Ecuador? None that I can see.There is certainly a difference between whether I proposition is true, and whether I know that the proposition is true. But that difference is not between whether I know that the proposition is true, and whether I am certain that the proposition is true, since in both cases, I know that it is true; for even if I am not certain the proposition is true, it does not follow that I don't know that the proposition is true.
