"That thinker writes books" is supposed to be correct
This sounds kind of odd and stilted in the English translation
Is "thinker" a type of work or position in Indonesia?
I guess it like in german we have "Dichter und Denker" = "Poem writers and Thinkers" which is meant for people like Goethe, Schiller, ... Who wrote very important classic literatur. They had high education and wer kind of a special socienty then.
Yet another word that is almost entirely useless in the real world.
