Hello. I am an English learner and have a question related to English. I have been reading a book which was translated into (American) English in 1904. In the beginning the author is introduced. The introduction includes a clause that goes "it is for humanity, pure and simple, that he stands". If I understand correctly, "pure and simple" defines humanity, which makes the clause "He stands for pure and simple humanity". Am I right? I am asking because for me it would make more sence (my native is Finnish) if it said "it is for humanity, purely and simply, that he stands". I am also not certain about the English language usage in the beginning of the 1900s.
