I will quote Rene Descartes:
Cogito ergo sum. - I think therefore i am. - I am, i exist.
Imagination adds, subtracts, divides and multiplies what has been always there. Imagination can only be, because its bearer IS part in a universe, or whatever, which BECOMES (therefore the bearer, we, BECOME too). I know this sounds dualistic, to be or not to be, grow or shrink etc. but that's what i believe makes relativism and philosophy possible.
Einstein once said: "Would the moon be still there if no one would see it?"
Hard to answer, because at the moment i would like to say "We cannot know it, we will always have to risk a look(proven by empiricism)." but then i realise, that the moon is a piece of the whole universe. So if i can see the Jupiter, or any other planet in this solar system, i might start to combine what makes it even possible, that the Jupiter is there. Further on i would realise (like the ancient mayas, aztecs and so on) that there has to be an earth with a moon and sun as well, because without these parts of the solar system there would be no Jupiter in the present state. That's like the dualistic dynamic table of content in this whole existence "system". Existence seems to fade and recreate, we might be too slow to realise the whole orchestra, or see drums and guitar only (scienes does cut off things of the whole and analyse these for example), but at last we will realise that it all connects to something bigger. Seeing, hearing, feeling, tasting, smelling combines, thinking (consciousness, inner virtuality, memory, processing, identity, ability to reflect, left and right hemisphere) adds up, makes us harmonic and feeling happy, mostly... And we all seek to be happy.
Well it always takes time to combine HOW things work with WHY and WHAT does even work...
But there is one thing, i am worried about: Whatever we do, we will only understand parts of the whole, as long as we are bound to these senses i mentioned before.
"The whole is more than the sum of its parts." - Aristotle
(Or: The whole is something different than the sum of its parts. Also: The whole is a part of another whole, paradox.)
The famous cake example:
You have a cake. This cake might consist of strawberries and dough, sugar, whatever. You could maybe endlessly divide these things, the strawberry into atoms, or quarks or how small it can get, and so on. But what is more important is, that you could put these things together in ANOTHER way, creating something different out of the same parts.
So to come to an end: I can think, my thoughts are part of a whole. I am more than the sum of my parts, aswell as everything i can imagine. This relies on relativism and a dynamic framework of table of contents and is also dialactic or metaphysic, however one might call it. There is always a reason, a background, as well as a progression.
Logic however, is the way we approach these things, makes us understand. Balancing out what fits together and what not to make it harmonic. And there will always be things we don't understand, then again we will have to use logic and imagination. It's part of us, so it's part of the whole, so it's part of the identity of the universe.
