A Little History of Philosophy discusses 40 different thinkers, starting with ancient Greeks like Socrates and going all the way to 21C. Each thinker (Some, like Charles Darwin, aren't philosophers in the traditional sense) gets their own chapter, and the stories flow together and overlap.

Instead of using complicated explanations, the author tells stories that about the philosophers that help us understand their thoughts, which I appreciated as someone starting to learn the subject. 

The book explains things clearly and shows how thinkers' ideas are connected, using thought experiments to help us understand better. I like how the author was able to make these thinkers feel like real people.

The book only talks about thinkers from Europe and America, leaving out many ideas from places like China, India, and the Middle East. It also doesn't include many women philosophers. As others have rightly said here, it should really have been titled "A Short History of Western Philosophy". 

Overall, this a great book if you want to start learning about philosophy. It's easy to understand and makes big ideas approachable.
