‘The Fox, the Shrew, and You: How Brains Evolved,’ an excerpt

In his new book, Rogier Mars provides a detailed account of animal and human brain evolution. In this excerpt from Chapter 1, he starts with the sea squirt—and why it needs the brain it eats after its larval stage.

Tom Griffiths describes how neural networks, logic and probability theory together explain cognition

In his new book, “The Laws of Thought,” Griffiths shows how these three pillars of study complement one another and together form a solid foundation to eventually explain all of our cognition, from brain to mind.
