It is but a step from the sublime to the ridiculous.中的but表什么

the sublime work of art enables us to momentarily stand eye to eye with insubstantial nature of our existence without tumbling into lethargy.
这句中的stand eye to eye 是什么意思啊
如果是立场观点看法一致的话，那么则翻译为：
崇高性的艺术使我们能够暂时对我们存在的非本真的本质保持一致，而不陷入困倦之中。
好像还是有点不妥

关于词性sublime

sublime 在这是名词吧?
形容词most 和介词短语of human emotions修饰它?
