I wonder myself about the theory of unique content, isn't everything we know just a regurgitation of another persons ideas/content?

Wikipedia is essentially a directory of information that already exists on the web. Everything you find on there can be attributed towards citated sources etc.

Also, the other thing about unique content is that its always getting ripped off by other sites, so for how long does it remain unique?

What I would like to understand is what Google defines as unique. Is it the content that has to be unique, or can it be the method in which the content is delivered (such as wiki)?
