Yep, my immediate thought on the question as well.
Interesting how in agreement, for the moment, the Hubski Philosphical Society is. Anyone out there familiar with the "perception check"? Maybe I'll blog on your question BLOB_CASTLE.hell, reality is subjective
Regarding perception, the sooner we realize that what we take in through our senses (our perception), and what we think these perceptions mean (our interpretations) are all subjective -- that we could have perceived other aspects of a phenomena and could have interpreted it differently -- the sooner we realize that, the fewer conflicts and misunderstandings will occur.
Hmm, very very interesting point. I'll be mulling over that for a while. I'd be honored if you did!
I realized that I have already blogged on the question of the subjectivity of rationality. Here, for example, and here, where I wrote "I asked a physicist friend of mine the same question. His first answer was that he was certain of nothing, but he later corrected himself saying that he was certain of things in proportion to the evidence available." and other places. I interpret your question: "Is rationality subjective?" to actually be the question -- what can I know for certain? what can I believe? As you say above I want to believe that there are absolutes
All of these is leading me to believe that there is nothing I can ever know for certain, which is something I suppose I already did know.
