，如禮何？，如樂何？= rituals according to what?
about 論語﹒八佾　子曰﹒人而不仁﹒如禮何﹒人而不仁﹒如樂何

james legge's translation:

(子曰) the master said 
(人而不仁) if a man be without the virtues proper to humanity
(如禮何) what has he to do with the rites of propriety
(人而不仁) if a man be without the virtues proper to humanity
(如樂何) what has he to do with music


traditionally, there're several ways to explain:

one is to expand the verses to "子曰﹒人而不仁﹒何以為禮樂"

(子曰) the master said
(人而不仁) if a man has no benevolence
(如禮何) how can he perform ritual
(人而不仁) if a man has no benevolence
(如樂何) how can he perform music


another is to treat it as "子曰﹒人而不仁﹒禮樂沒奈何"

(子曰) the master said
(人而不仁) if a man has no benevolence
(如禮何) what can ritual do
(人而不仁) if a man has no benevolence
(如樂何) what can music do


have fun :)
