Well, the universe in which we live is nothing more than a subjective model of what we sense. We can never be sure of any truth other than what's in our heads, so in that sense, every experience should be valued and treated in its own right.
Psychedelics have taught SWIM that even the strongest held-beliefs can be destroyed with simple abstract logic, and that the strongest-held logic can be destroyed with a strong enough belief. Really, one shouldn't worry about what's right and wrong, and show respect to every experience. Spiritually, I find life isn't about faith nor science in entirety these days - it's a balance of what exists in the universe, in your head. Because that's all you can be sure about. And that's You.
If a tree falls in a forest and there's nobody there to hear it, does it make a sound?
Well, since my universe is perceived, and everything founded on knowledge and senses... If I perceive no sound, then in my universe there is no. If I know there will be a sound, there is. If I know nothing of the whole scenario, there is no sound. The concept of sound is subjective and artificial, a construct of consciousness.
The opinion I'm holding to at the moment is, if it matters to me, it matters to me. It doesn't matter if it's true or false, as long as the effects and consequences pertain truly. If SWIM meets with spirits, he has evidence to disprove either argument, but if he suspends belief of their reality, he's insulting either them or himself. Either way, these days, I feel the urge to relax judgement on unanswerable questions, and interact as my existence intends me to. Nothing should be forced. Openmindedness is the key to spiritual expansion. If you can provide me with a proof of either way, with _No_ counterarguments whatsoever, I will believe it.
If the truth can be explained to as to be understood, it will be believed.
Peace out.
