How Are We To Know?

Free eBook “How Are We To Know?” by Nils J. Nilsson. This book makes the following points: 1) in analogy with robots, we humans know by the models we make of reality, 2) these models are always provisional and sometimes unreliable, 3) it is especially important to examine thoroughly those models upon which we base actions, and 4) the scientific method provides an excellent guide for such examination.


This book is about beliefs—how we get them and how we evaluate them. It takes the form of a fictional conversation among three people and Gio, an intelligent robot. Mia designed Gio, Nick is a philosophy professor, and Sam, a college student, asks many questions. Gio “uses the Web” to augment the conversation with lots of supporting quotations and illustrations.
