So here is my question for those who believe facts are subjective. Can any one thing be true for all people. And before you say yes or no, think hard about this question.
And Seoul, I did think about medicine when deciding to bring up this subject, as that is something that should be taken into consideration. Thanks for bringing it up.
This is really a fascinating question, Viola. I do believe that some things can be facts for everyone, such as that Jesus died for us and faith in Him is the only way to heaven. Now of course, a lot of people don't believe that at all but for us as Christians, this is a fact that applies to everyone.
But then I think about things such as, "Yellow is yellow." And then I think about how many shades of yellow there are and where is the dividing line between yellow gradually becoming orange? So many people see shades of color very differently. And what is "yellow" for a person born blind and therefore has never seen yellow with their own eyes? As another example, take the color turquoise--a good percentage of people will call it "blue" and another group will call it "green."
There are so many other things, most especially medical, that I do believe are extremely relative. Bee stings, peanuts, alcohol... several factual statements could be made about them that are, on the surface, true. But that completely changes if you are allergic or an alcoholic. And if you've never encountered someone who is, you think you know all the "facts", until you meet someone for whom they do not apply.
My ex and I had very different reactions to some substances when compared other people. For instance, I have a very odd relationship with caffeine. Unlike other people, I can't have a cup of coffee everyday or I will literally be up for days until I eliminate it for a few more days. (I am sensitive to ANYTHING with caffeine in it, including chocolate.) MSG gives me migraine headaches. These chemicals seem to "build up" in my system and take a longer time to wash out than most people.
Although I can tolerate a little, alcohol does NOT give me "good feelings" or make me feel "relaxed." It seems to build up in my system very quickly because my body isn't processing it and if I have too much (which for me, can be 2 drinks), it will hit my stomach like a trampoline and be completely rejected.
My ex was one of those people who discovered the hard way (at the dentist's, no less) that he needs 2x or more the regular dosage of numbing/pain killing drugs because he was the opposite of me--his system washes things out so quickly that he needs huge amounts in order to take any effect, whereas my system seems to "hold on to things" and processes them at much slower rates.
Scientists could list every fact they knew about how such things are biochemically processed within the body, with all the research to back it.
But for people like us, those "facts" simply do not apply.
