Rational beliefs should be able to withstand scrutiny and opposing arguments. The inability to do so indicates that the belief is more about personal bias and emotional investment rather than objective analysis.
I didn’t originally state that past observations are rigorous; that is the conclusion of the entire body of science and human understanding since its inception. I absolutely get what you are saying, but unless you can cite a really good point-by-point takedown of John Locke, David Hume, Karl Popper, and the like, none of this holds any water.
Put very simply, the common epithet, “the definition of insanity is doing the same thing over and over again and expecting different results,” has its roots in meaningful philosophy. Past experience is literally all we have, and any system of thought that discounts this is operating on less than nothing.
Sadly, you seem really out of your depth here. I won’t argue any further because of this, sorry.
I recommend reading up on basic philosophy of science, human knowledge, and methodology.
