About truth. Some thoughts.
Google: opinion - a view or judgement formed about something, not necessarily based on fact or knowledge.
Read the words, all opinions are not false, because some opinions are based on fact or knowledge. Knowledge first - to know that or to know how to. I know if something is subjective and I know how to do that, I just do it and I just have done so. That is true, because it is so.
Google: truth - that which is true or in accordance with fact or reality.
Read these words, is it a fact and in in accordance with reality, i.e. what goes on, that I am writing this? Yes, it is true. Is it objective as independent of all human brains/minds? No! It is subjective in part. These words are caused by processes in my brain and they are about how I think and feel.
Reality to some people: What which is not dependent on brains/minds. That sentence is dependent on brains/minds and it can falsified. You just answer no!
I once read the following definition of the universe: The light that comes to us. Now think no and answer: No! And then ask, if that is a part of the universe.
We are debating the ideology of what reality is. That, we are debating that, is a part of reality, no matter how subjective it is.
For all of the fancy words, like falsifiability, test, replicate; I can try to replicate your ideas and then I notice I can do it differently. Just as some people don't believe in god(s), I don't believe in your way of describing reality, because I can do it differently. And yes, that is true, real and a part of reality. Subjectivity is just as real as objectivity and if you deny that, you confirm it, because you use subjectivity. That is the reductio ad absurdum of "reality is objective".
