When phylosphers make such sentences they are only interested in making them look smart and intelligent and to hide that they have acctually no meaning and that they are just playing with words.
They don't care one bit to try to make what they want to say easy to understand.
This is totlay in contrast to scientific approach.
Sciense really tries to teach people how things work, tries hard to transfer knowledge in the most simplest possible form, and never says that someone is to stupid to understand something which is the common apporach of philosophers.
You cant jsut say stuff like
"determinism is nothing if not expressed through its objects"
"AS, a determined thing, I can never say 'yes, this is what I am determined by'"
withouth proving or providing flow of thoughts which resultet in this conclusions.
You argments are no differetn then saying three time "Determinisam doesn't exist".
You only mask this by going few step backwards invetning some unproven assumtions which then lead to also not proven conclusion that "Determinisam doesn't exist".
