Puritan fanatics brought to civil and military affairs a coolness of judgment and mutability of purpose {that some writers have thought inconsistent with their religious zeal}, but {which were in fact natural outgrowths of it}.
兩個關係子句平衡: that(受格,限定用法)..., but which(主格,非限定用法)... ,共同的先行詞是 {a coolness of judgment} and {(a) mutability of purpose} ('判斷的冷靜'和'意欲的可變性'); it = zeal
a coolness of judgment 和 a mutability of purpose 平衡: a 加在不可數名詞所引導的片語前,片語中有其它資訊時 (i.e. judgment, purpose), 把名詞片語視為一個單位.
