Upon this rock, the truth of the existence of matter, I build my argument for the existence of an immaterial first cause, an uncaused cause.
We see that materiality exists, a materiality that can be bound and divided into parts by nature of its existence as materiality. We also know that everything material is caused in some capacity. Every cause, then, has a cause.
If every cause has a cause, one could say that there is no need for a first cause, however this would lead to an infinite regress, which is an absurdity. It’s a contradiction. It’s like saying something is infinite and finite at the same time. The universe necessitates an end to the chain, making a first uncaused cause necessary. This also demands that something be outside of that which is finite, to be that which gives possibility to finitude. Without this possibility of finitude, nothing material would exist. Therefore, the material world demands something greater than itself for it to exist. In the material world there can always be something greater, but to an extent, for no matter how great, it is still finite - a material thing that can be bounded and divided - and can have something greater than itself though finite. This cannot go on again and again endlessly, as if it did, the greatest thing would by necessity not be material, but if immateriality is impossible, something infinite and non-materiality that is materiality would exist, or rather an infinite finite thing would exist. Infinity would be divisible, able to be bound. It is the nature of materiality, not to be infinite, as it is able to be encompassed and bound and divided into parts, by definition. Therefore, this infinite cause must be something other than material, something immaterial.
If nothing immaterial exists, then nothing material is possible, because it would contain infinity within it, which is a contradiction. Material world demands immateriality, or else materiality would have infinity in it, or in other words, the materiality would contain immateriality, a concept and word, which is another way of referencing that which has no finitude, bounds, and is infinite. That which has bounds and parts would be infinite, which is impossible. The finite would be infinite.
In the material world, everything is finite, meaning it has limits and boundaries. But if something were infinite, it wouldn't have those boundaries. It wouldn't be subject to the same rules. So the idea that something could be both at once, both infinite and finite, would violate the very definition of material things, because it would mean it had no limits but still could be divided and measured.
This contradiction demands that there is immateriality that encompasses materiality, and that this immateriality be the first cause or uncaused cause of materiality.
