Sequences are collections of blog posts by Yudkowsky grouped by topic. Here is the index of all sequences:

The main sequences are "Map and Territory", "Mysterious Answers to Mysterious Questions", and "How To Actually Change Your Mind".

In my opinion, "How To Actually Change Your Mind" is by far the most important. Notice that it consists of several "sub-sequences". Here is the index:

Having now read EVERY post by Eliezer Yudkowsky on Less Wrong, I can say I have thoroughly enjoyed it and benefitted immensely. The Sequences are a smaller portion conveying many important ideas, but by reading all the posts you get a stronger sense of direction, and see where all of the philosophy leads to.

Incredible ideas, by an incredible thinker.
Ivan Vuković
The book is very informative and I really liked some parts, but it was a very difficult read. Why? Because Yudkowsky simply LOVES beating a dead horse. There's just too much repetition and sloppy writing, although the ideas are great.

It's just... It ought to be more concise and clear.

This is about how to overcome bias, which is really important in order to take good decisions, so I recommend it to most people. And it's well written, so it's fun to read! The first sequence was about bayesian probability, which is something I already knew about since I study physics engineering, but I've still learned new things. And in the other sequences, I'm definitely learning a lot.

As it is impossible to finish these things - re-reading has to start even before one reaches the end - I arbitrarily pronounce them read now.

The best and most life changing thing ever.

This one was really hard to rate as my reactions to each post and sequence varied from "jeez, this just nailed it" to "meh, why are you explaining the same thing over and over again". I admit only skimming through many of the metaethics-sequence posts and might have given four stars if that one was left out. My rating doesn't reflect on how much I appreciate the writer doing and writing what he does - it IS important trying to explain things out in various ways, even for the people with creation ...more

The Sequences are blog posts from Eliezer Yudkowsky written from 2006 to 2009. Subjects include Rationality, cognitive biases, some psychology, evolutionary psychology, quantum physics, morality and more. The second and third books were my favorite.

A truly well written and organized collection about how to inspect your own mind from the inside. Reading this has enriched me greatly.

It's worth 4,5 stars, but it's a so important reading that it received five.

“It's a most peculiar psychology—this business of 'Science is based on faith too, so there!' Typically this is said by people who claim that faith is a good thing. Then why do they say 'Science is based on faith too!' in that angry-triumphal tone, rather than as a compliment? And a rather dangerous compliment to give, one would think, from their perspective. If science is based on 'faith', then science is of the same kind as religion—directly comparable. If science is a religion, it is the religion that heals the sick and reveals the secrets of the stars. It would make sense to say, 'The priests of science can blatantly, publicly, verifiably walk on the Moon as a faith-based miracle, and your priests' faith can't do the same.' Are you sure you wish to go there, oh faithist? Perhaps, on further reflection, you would prefer to retract this whole business of 'Science is a religion too!” 33 likes
