You just said that some things are in fact knowable... then you closed by saying that you "do not claim to know that [your opinion] is absolutely correct." Well, which is it? Are there absolute truths or aren't there? Why shy away from claiming unabashedly that there are absolute truths when you know this to be the case?
The reason I don't claim to be absolutely correct is because I am depending on my own imperfect capacity to think and reason, in order to even make such an observation. And also just merely from humility, I try not to make a habit of presuming, when it is always possible that there is something I have not yet considered that would change my mind.
