What makes something sacred?
Othering is an interesting phenomena, and psychedelics undoubtedly invoke other.
Science is a method, not an ontology or a set belief or even a set of beliefs.
How can one disprove or prove a method?
Science as a method is experience based, but it takes into account that experience is subjective and seeks to employ a criteria that allows a more objective approach.
That sounds really open minded and insightful!
I did a little scientific study the other day, I had two apples and I ate one and I had one left.
But I can't safely assume that I ate one or had one left?
That is what you are saying right?

So what about the experience of people doing scientific studies?
What you are saying strikes me as incoherent, clearly it makes sense to you.
Have you ever been wrong about something that made sense to you?
Have you ever had an experience that misled you?
I have in both cases, because I am after all only human.
