【请教】OG12 RC的一个句子意思

twzh

OG12 第三篇阅读（第362页）。

第三段倒数第三句：“Here we part company”.

不太明白这个句子的意思，“part”在这里作何解释，请教高人～～ 谢谢啦～～！

我把整个第三段贴出来：

You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, which should be available for all to appreciate, not sold to the highest bidder. I agree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that comes out of the ground has scientific value. Here we part company. Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong.

谢谢楼上两位
我又查了查，证实两位的理解是正确的：
part company：
a. to bid farewell or go separate ways; leave one another.
b. to dissolve a personal affiliation, relationship, etc., esp. because of irreconcilable differences.
c. to disagree.

同意楼上。Specifically,
"part" here is a verb,means:(of two things) move away from each other "company" means: the fact or condition of being with another or others, esp. in a way that provides friendship and enjoyment

Here we part company.我觉得应该是说，在这一点上我们的观点是不同的。part company：分开，分离。

我觉得是这个意思～
之前没想到company的“伴随物”的意思
谢谢啦～～～

我觉得是“我们从中分离了一部分“的意思。（其实这句话是总结前面的一句话“所有的东西的产生都是有科学价值的” ）不知道这里理解对瓦。
