I was at the sea shore again. On the way back it suddenly occurred to me that what Rav shach is answering to his question on Tosphot (kidushin page 2) is the exact mirror image of the answer I was trying to give. Rav shach is saying that money acquires, refers to a case where there is something acquires and something that causes the thing to be acquired. This is not the same as something causing an act. Thus, the Canaanite slave can be freed by money or the value of money since it is a case of his being freed. But a Jewish slave is the same thing as being hired to do work for a certain number of hours--just longer hours. Thus, his being freed is a case of a monetary act. [this is very different tan the Canaanite slave being freed upon which his entire legal status changes. Upon being freed he can marry a Jewish girl and he becomes obligated in all the commandments. this is the polar opposite of what I was saying that the Canaanite slave acquires himself, so that is a case of something being acquired and something causing it to be acquired. But the Jewish slave does not acquire himself upon being freed. He does not own himself. He is freed.--------------------I was at the sea shore again.
