君道何如
"how should a ruler rules" is good, in english. however, as a translation, it's not.
"何如" --> "how should, it's ok; but the remaining, "君道" --> "a ruler rules", well, improper.
cause, "君道" as a noun here, is an entity, which is the same, in verses before this one:
而君道不廢者
and (而), the principles of sovereign (君道) is not (不) discarded (廢)
而立其行君道者
and (而), support (立) the one who (其) carry out (行) [according to] the principles of sovereign (君道)
briefly, "何如" can be translated to "how", in most occurrences in the book 呂氏春秋. sometime, it's better to translate it as "what".
about "君道", it's an entity. divide it into subject + verb; well, would be betrayal :)
