Concerning the question »Is it more common to write longer sentences in german than in english?«, I wonder why some well-known English philosophers bothered to learn German.
A lot of important philosophy was written in German in the last centuries (Kant, Hegel). There are translations. But do these philosophers prefer to read it in original language? And why? Are there advantages in writing complex differentiated thoughts in German? Or are there only bad translations available for these old texts (I doubt this as they are ground-setting for many philosophical disciplines)?
A big advantage for me is the convention to capitalise the first letter of every noun as it makes it easier to read a very sophisticated philosophical text. Also heavy subordinate clauses arguably help expressing, how a single thought is related to another one in a hierarchy of thoughts/proposals. German language just seems to be very exact from this point of view and to have more options expressing complex thoughts in an easy manner.
Any scientific links on this topic would be highly appreciated. As you might know, the right programming language can save a lot of time formulating a distinct problem as a computable algorithm. Is the above an analogy from spoken languages?
