But if there were nothing beyond the DNA in cells, life could not exist.

VOA: special.2009.12.08

If you find this argument convincing, what it's an argument for is the claim that even if souls do exist, they may not be the key to personal identity.

如果你信服这个观点，我们要证明的是,就算灵魂真的存在，也不是人格同一性的关键。

And again, I'm not gonna go on and on about this point, it worth noticing that even if you do believe that soul exist, nothing stops you from accepting the body theory of personal identity.

重申一下，我不想一直,讨论这个问题，我们得明白,即使你相信灵魂的存在，你也可以同时接受,人格同一性的肉体存在论。
