adventitious

It was then that the ecstasy and the dream began, in which emotion was the matter of the universe, and matter but an adventitious intrusion likely to hinder you from spinning where you wanted to spin..到了那时候，狂欢和梦想也就开始了，在这种狂欢和梦想里，激情变成了宇宙的物质，而物质只不过是一种外来的插进来的东西，有可能妨碍你在想旋转的时候旋转起来。

If this assumption be admitted, of course a union of God with the world renders God completely finite, and degrades Him to the bare finite and adventitious congeries of existence..如果承认这个假定，则上帝与世界合而为一，是不啻将上帝纯然有限化了，贬低成为一个仅属有限的存在之外在的复合体了。
