Do rainbows exist objectively?

    Or like the minecraft example. Did minecraft always exist even before it was ever invented ? The POTENTIAL of it did, so in essence EVERYTHING exists, but it.. ya know.. doesnt exist either until someone can acknowledge it as a thing.

    It's fine make fun of me I'm bad at this.

    No you're okay. There's a concept called conceivability. Essentially, there are things that could possibly be but are not for contingent reasons.

    I wouldn't say they already exist in a meaningful sense though. But there are as many people who disagree than agree on that.

    So what are you saying ?

    All things are Conceivable.

    No, for example a square circle is inconceivable, it's just a set of words that don't grammatically clash, it's a valid sentence but the fact of it is impossible to even make sense of because it's internally as elf contradictory. Even a circle with a ratio of circumference to diameter different than pi, is

    To answer your question more specifically: a perfect circle doesn't exist anywhere in the world but we do believe in the existence of "the circle", at the very least as an abstract object.

    Just depends what you mean by existing.

    Oh so that's why Maynard named his band a perfect circle.

    I guess by existing I mean .. ya know... like I said.. the potential
    . Better re questioned by me would be , is there a thing that does NOT potentially exist ?

    Anything inconceivable, like a square circle.

    I can conceive a square circle. I CAN. answer my question

    No you can't. You can put those words together but what are you referring to?

    A circle in the shape of a square. What are you talking about ? You still havent answered my YES or NO question.

    A circle is a shape, if you change the shape of a circle, it's no longer a circle. If you make it a square then it's no longer a circle.

    A circle has infinite vertices but a square has four. A square's internal angles add up to three hundred and sixty degrees whereas the internal angles of a circle are essentially infinite.

    Yes there are things that do not potentially exist, like a final end to this thread.

    Shapes are changeable is what you're saying and I agree. All squares are circles and all circles are squares.

    You still havent said yes or no .

    No, a circle is defined in part by qualities that are mutually exclusive to the qualities of a square.

    I already said yes.

    He's implying if nobody looked at the colors, they might not be there anymore, or maybe never really were there.

    Optical illusions aren't wholly subjective either.

    Yeah Ramachandran et al even managed to create a brand new, never been seen before "optical illusion" via neural stimulation based on the predictive power of neuroscience.

    Every subjective experience has an objective cause. Wavelengths of light do not become colour until they enter your eye and are interpreted by your brain. Or maybe I'm wrong and the world is full of tastes no tongue can know and lights no eye can see and when there was no ear to hear, you sang to me.

    Epistemically the means by which we know these things are ontologically true are by our experience of them. If for example you never tasted chocolate, you could do whatever scientific description you wanted but you would simply not be able to actually tell what chocolate tastes like until you eat it. Many things we know "in theory", we don't really know, such as the smell of hydrogen sulphide. And many things other people know for sure, you don't know at all, such as a known flavour you have never tasted.

    So, we only know light by looking at it. Sure there is a scientific description of it out in the world, but it's only a limited description of our observation.

    So in a very real way, that light is coloured whether you are currently looking it or not.
