I grew up in South Africa and I would look at maps and we were at the bottom of the world. There was this whole thing up there. I was always reading encyclopedias about the world. So travel was something I was always attracted to.

Open-source encyclopedias such as Wikipedia and search engines such as Google and Bing, which people can tap into anytime and anywhere via computers and smart phones, put a world of knowledge at our fingertips at a lower cost than ever before.

Cos if it's encyclopedias we've got enough, like, information... and if it's God, you've got the wrong house.

In a sense words are encyclopedias of ignorance because they freeze perceptions at one moment in history and then insist we continue to use these frozen perceptions when we should be doing better.
