If causality is the pre-existence of a thing, it is evident that the existent is really divided from a
caused cause, and so that there is no logical necessity that what exists be caused.
We look for causes because the paradigm case of explaining what/why a thing exists involves tracing it back in time behind that threshold when it began to exist. In crossing over this threshold, the causes emerge, diverse and converging on the existent.
Causality does not mean the same thing in what does not come to be, i.e. mathematical or spiritual things (Newton placed mechanics prior to geometry, as the producer of the geometrical forms. But this is either metaphor or nonsense.) These things only pre-exist in mind and not in anything outside of it.
Becoming, or nature, is pre-existence outside of mind. Nature has a double reduction to its pre-existence outside mind, and in this line it is somehow infinite; and to the mind in virtue of which nature can be “outside”.
