大全88读起来不是很顺手，其中有2句话看起来有些怪异，不知道是否是录入时候缺少什么东西才导致理解起来很难。搜索了一下，也有cder以前问过其中的1句话的意思，没人回答。现再发，请nn指点，多谢！

1，Shaw, whose essential modesty is as disarming as his pose of vanity is disconcerting, assigns to himself the role, not of the master, but of the pioneer, the role of a Marlowe rather than of a Shakespeare.

2，No one, says Shaw, will ever write a better tragedy than Lear or a better opera than Don Giovanni or a better music drama than Der Ring des Nibelungen; but just as essential to a play as this aesthetic merit is moral relevance which, if we take a naturalistic and historical view of morals, it loses, or partly loses, in time.
