Books which, after you read them, made a huge impact on the way you viewed the world

A few of mine:

The Letters of Adam Hope

This is a book that was put out in a small batch by a Canadian publisher. It's a collection of letters written by a Scottish immigrant to Canada in the early 1800s. The light switch that went off for me when reading it was how important the correspondence between Hope and his family was. Counter-intuitively, it was actually one of the aspects of his life that he cared about the most. It really shed a light for me on how prominent communication is as a part of the internet and information age. In other words, one of the main things to emerge out of the internet is communication with higher efficiency. Probably a sign that this is what people really care about.

Maps of Time: An Introduction to Big History

No particular perspective came to light when reading this, it's just world history on a macroscopic scale done really well.

Paul Johnson's 'A History of Christianity'

Just another good history on a topic that's very relevant to the world around us today.

Hume's Treatise on Human Nature

Specifically his idea that learning new information about an object changes our definition of the object.
