法理学范围 (by austin)书中一句话如何译？

qishuian

such question arise mainly from the fact that,as a subject,jurisprudence is occupied with different issues and generally takes a different approach from the other, mainly black-letter,law subjects,in the manner in which it deals with the subject matter of its enquiry.

前半句的意思可能是“这些问题产生于，作为一门学科，相对于法律的其它学科而方，法理学涵括了不同的议题，并且采用了不同的研究方法，” 但“in the manner in which it deals with the subject matter of its enquiry.”这句就不明白了。

望达人帮忙？ 将该句翻译一下。
