Okay, I will answer this one first and get the other at the end.
I will start with religion. Now if you hunt the Internet high and low, you can find at least 3 definitions of religion.
Google, one from Britannica and the notes from a lecture in the philosophy of religion.
They are not the same and for the 2 later ones, which are both from scholars they are not in total consensus.
So here is the last one to the following effect: Religion is about (human) values. That means I as an atheists is religious, because I have human values. So now for consensus and try to figure out how that relates to this about science.
"Science, since people must do it, is a socially embedded activity. It progresses by hunch, vision, and intuition. Much of its change through time does not record a closer approach to absolute truth, but the alteration of cultural contexts that influence it so strongly. Facts are not pure and unsullied bits of information; culture also influences what we see and how we see it. Theories, moreover, are not inexorable inductions from facts. The most creative theories are often imaginative visions imposed upon facts; the source of imagination is also strongly cultural. [Stephen Jay Gould, introduction to "The Mismeasure of Man," 1981]"
So here is the end problem with consensus:
Cognitive Relativism | Internet Encyclopedia of Philosophy
Go to
3. The definition of relativism
And read it and compare with the quote from Gould and this old one, which still holds:
"Man is the measure of all things: of the things that are, that they are, of the things that are not, that they are not." Protagoras
It should be noted that it is about moral, cultural and social relativism.
So back to reality: That word is only around 500 years old, so before that it there was no reality for humans to speak about, yet there were apparently humans. In other words reality is a social/cultural construct about how to understand the world but there are different constructs about how to understand the world.
And since I am a classical skeptic from the tradition of philosophy and not a modern scientific skeptic, I do it differently. And in all likelihood I will never be a member of a consensus,, because I am an old school skeptic. And I don't believe in world understanding of modern western scientific skeptics and atheists.
