I am never surprised at the different interpretations different people will put on the same piece of artwork. So it shouldn't come as a surprise when different people see different meanings in the same picture of anything. The whole of life is a series of perceptions that we have to navigate, so you just have to trust your BS meter and do constant reality checks.

Healthy levels of skepticism and optimism.

I could always ask a friend(s) to tell me their perception of what I see as a "truth" or concept.

"Perceptions are individual's truths."

Not always. When I percieve Penn & Teller do 'magic' I don't think it really is magic but a clever trick.

"How do you check your perceptions to know that you are getting an adequate picture?"

If your perceptions create a blind spot you can't because see because you're blind to it & therefore cannot doubt what you think you really 'know'. The only thing you can do is tell yourself that you actually don't necessarily 'know' anything at all & everything you think you do know is simply a belief. Once you can accept that everything you think you know is ultimately just a belief (or might be - don't take MY word for it!) then you may - perhaps - be able to look at how strong the support for you belief really is if regarded from an opposing perspective & care about the possibility that you may not actually have good reasons for believing what you consider to be 'known facts'. - But beware, it's very very easy to shoehorn bad reasoning into seeming justified when all you've really done is not tested your beliefs to destruction when you could (if you should). That's a problem because your blind spot is carefully maneuvered to cover problematic areas you may not wish to examine closely. To do that you simply have to care more about kidding yourself than being "right". This means challenging your most cherished beliefs more deeply than any other beliefs.

Ask a simple question: who is benefiting? Is there a conflict of interest myself included. Also, and most importantly, Have I had any experience in the particular issue? Have I seen multiple sides? Does it help or harm the ultimate moral - will it lead to further destruction of life, our own included or will it help preserve LIFE (writ large).
