Oh my a God! The search for 'truth' is different then reality in the natural world. The issue I have is this...the color blue is the best color and anyone who doesn't accept this is wrong, and in some cases should be put in jail. Abortion is wrong and it's okay to tell others what to do. Jesus is real and I hear his voice telling me what to do. Crime novels breed crimes. Climate change is just a hoax so I don't care. People who have experienced trama should be able to just get over it. Woman are smarter than men.
What of this is reality, what is truth, and what gives you the right to tell me what to do?
I tend to think of a spectrum of needs and conditions. Explaining the 'truth' of the natural world is science. Some truths are the realm of ethics and morality, and should be shared values in a community, although one's absolute truth in many cases is flexible and conditional. Murder is bad unless you are protecting your home and family.
And some are beliefs that should be personal.
