Godel, Escher, Bach changed my entire world view.

How so? I read it, and though very good with the logic/math, I wasn't as moved. I'd love to know more about your journey.

Edit: For me 'Information' by Glieck was very good, as it summed up the logical 'journey of man' as a struggle to refine signal to noise. When interpreting math/logic as such, I was floored and a lot of things made more sense to me.

I read it while in college. It put me into a mental space where I was considering recursion on a universal scale for the first time. I'd never considered, previously, how recursive processes construct everything I see and experience, including my own consciousness. It was the most beautiful idea I'd ever come across and satisfied my need to answer how we came to be.

This has been my number one book for pretty much my entire adult life.

It's worth the read, 100%.

I second this - on both books.

Two great books.
