Myself, I believe in my understanding. I do so because my decades long skeptical pursuit of information is a process, a life's adventure.
Everything is a process?
But in its simplest form, process philosophy is about engaging in the process of what we are, what we do, and how we can guide, develop and create our own future.
Novelty and adventure:
The authorities of history were interesting, but not to be followed blindly. Experience and adventure, and the risk of the unknown: these are what drove his metaphysics.
Process emphasizes the space between two points. It's neither the start that's important, nor the end; but the travelling between. In the case of Whitehead, this travelling in between is what makes up reality.
Nothing is true:
A key implication of his work is that reality doesn't have to be like 'this' or like 'that'. There's no ultimate reason why we are living in this way, in this world, in this universe.
Notwithstanding Whitehead's theism, process philosophy sans religion, is akin to taoist philosophy!
Is change the only constant in the universe?
But the Universe itself experiences continual growth, constant change, and new experiences all the time, and it does so spontaneously.
But the Universe, very clearly, doesn’t care what units-of-measurement you use! So we can create dimensionless constants, or combinations of these physical constants that are simply just numbers, numbers that describe how different parts of the Universe relate to one another.
So, physical constants are just numbers.
And how do these constants emerge?
This is, I’ll note, a source of much distress for theorists, who hoped that these constants — the fundamental masses of the elementary particles — would either be part of some pattern (they’re not), calculable from first principles (they’re not), or would emerge dynamically from some larger framework, like a GUT or string theory (they don’t).
What we don't know:
We don’t yet know where the values of these constants come from, or whether that’s something that will ever be known with the information available in our Universe. Some people chalk them up to anthropics or appeal to the multiverse; I haven’t given up on our Universe just yet, though!
Our journey through the cosmos continues, and there’s so much more still to learn.
