In western countries, nearly every imaginative painting of Adam and Eve

This is too generic to have a meaningful discussion IMO.
Take a more specific claim as an example. Buddhism claims that mind doesn't
disappear when you die, and it can migrate from life to life carrying over
karma, etc. Mind is theoretically observable, e.g. 他心通,or some
scientific instrument that has yet to be invented. So it's possible to
observe whether mind migrate from life to life at the time of death.

For music files, migrate them in iTunes:
0 Open iTunes
1 In the preference, set the music location to the new location
2 File->Library->Consolidate Library.
This will copy the songs to the new location.
For the library, migrate them in the Finder:

虚拟机之所以流行,是因为几十年的操作系统研发都没有彻底解决隔离机制(isolatio
n)的问题,最后不得不采取虚拟机这种开销相对较大的方法。一般文章和课本中都会谈
到隔离是OS的一项功能,但一般都不会强调现有OS实现存在的问题。如果没有认识到这
一点,就很难理解为什么虚拟机会这么火。隔离是如此重要以至于可以牺牲20%的性能。
目前OS的隔离大致有下面几方面:
1.硬件和软件的隔离。用系统调用API来抽象底层硬件,这样应用程序就不需要考虑不同
厂商的硬件间的区别。理想的情况是只有一个标准的API,但现实是流行的操作系统有3
个,每个又有若干个版本,以至于API兼容性本身成了一个问题。这个问题的解决方法是
虚拟机。较早的尝试是java虚拟机,但是java这语言本身不怎么行,没法一统天下。最
后绕了一圈发现Intel的体系一统天下了,硬件间的差别没有软件的差别大了,于是就有
了虚拟机。跨体系的虚拟,比如IA32和sparc之间,目前还是没法有效实现的。
2. 用户间的隔离,主要是对恶意用户的隔离。一般OS通过给对象(文件,进程等)加用
户权限来实现隔离。这点*nix类系统做的比较好,win... 阅读全帖
