ecsniffer is right. a few more points here:
1, this is REVERSE: bring A to B ---- here, it is 'bring to BA' because A is too long
2, the subject of A is ' a coolness of judgement and mutability of

3, 'though inconsistent' is 插入语, modifying the subject of A. Below is a sentence I forged according to this one:
It is
fear that brings to our lives motivation that though not preferred we need to
move forward, and which actually becomes a driving force towards our
achievements.ffice ffice" /> |
