"In my heart of heart"

在我内心深处

"Give me that man

That is not passion's slave, and I will wear him

In my heart's core¹, ay, in my heart of heart,

As I do thee."

“给我一个不为感情所奴役的人，我愿意把他珍藏

在我的心坎、我的灵魂的身处，

正像我对你一样。” （朱生豪译）

莎士比亚用法：

While speaking with Horatio, Hamlet says this phrase noting that if there's a man who is "not passion's slave" — aka, a master of his emotions — then he'll put him close to his heart. Using the language "heart's core" right before suggests that Hamlet means some very deep, central part of his heart/emotions.

哈姆雷特跟霍拉旭说话时用了这个短语，强调如果有一个“不受感情奴役”的人，即能够控制自己情感的人，那么他将把那个人藏在内心深处。上文中曾提到“心之正中”（heart's core）一词可以看出，哈姆雷特指的是他内心和情感最深处、最核心的部分。

现代用法：

Nowadays, we pluralize the second "heart" to say "in my heart of hearts." The phrase refers to one's inner-most, secret thoughts.

如今，我们常把第二个heart改为复数，使用in my heart of hearts这个短语，用来表达人内心最深、最隐秘的想法。
