From a post by Jonah Goldberg on "The Corner", a blog hosted by National Review Online:

Compare the results of a Google image search for "tiananmen" on American Google with an image search on Chinese Google.

Click the links and check out the difference for yourself.

If you want to make a car you need to define "what is a car", so far so good ... If you want to make "life" they will first need to define what exactly the criteria are before we can call one of their siblings "life".

Is it life because it moves,breathes, contains other cells, eats, sleeps, breeds, farths, burps ??

At which point exactly do we call an life ?
