What "doctrine?"<quoted text>
Again you are advocating the Scientism doctrine.
Here's a question for ya:
"How far do you think science can and should offer answers to the questions that are still considered the domain of philosophy?"
For example, can facts settle the issues of human existence such as what is right or wrong? Do you need to be scientific to be an ethical human being? Do you have to be scientific when it comes to making informed decisions in life and think of solutions to the problems you are facing?
And yet, you keep pointing out logical fallacies here that you learned from philosophy, you are a hypocrite. Just face reality! Who are you to determine what is objective reality for all of us?
Also, yes, ethics are subjective, to gain an objective perspective on what's good and bad one needs the scientific method. Without objectivity you have people sacrificing other people to make believe gods or claiming that "spirits" told them to kill or forcibly submit an entire culture.
