You are ready. You don’t read math book like you read a novel. You can literally spend days on one page. You are not going to find a better book than Halmos’s. Every mathematician agrees that every mathematician must know some set theory; the Naive Set Theory. Authors; (view affiliations). Paul R. Halmos. Book. Every mathematician agrees that every mathematician must know some set theory; the disagreement begins in trying to decide how much is some. This book.

Just like everybody who uses mathematics just assumes that the real numbers exist and have the obvious properties. Moreover, every set has more subsets than it has members, so its subsets cannot all be members of it, although in some instances some of them are. If you do have a somewhat fitting background, I think this should be a very competent pick to deepen your understanding of set theory.

The author shows you the nuts and bolts of set theory and doesn’t waste any time doing it. I want to be able to express set notations fluently in math fields used in machine learning, so I started reading Naive Set Theory by Halmos.

In particular, in the conventional Zermelo—Fraenkel theory, no set is a member of itself. I am sure the book does what it claims, gives you all the foundations in set theory to go on to bigger and better things. You’re using the fact that the integers are a set, or that your graph has a power set, and the availability of separation or bounded comprehension. This book seems well-suited for a layperson interested in learning set theory.


It did more than enough for me, even without the last few chapters. Is it a good book? Before diving in to the review it’s important to remember that the usefulness of a math textbook is heavily dependent upon your math background.

Which you cannot possibly accomplish otherwise. The axiom theor substitution is called the axiom schema of replacement in modern use. theoru

Book Review: Naïve Set Theory (MIRI course list)

Once you understand propositional logic, make it your goal to understand “first-order logic. Se review the content before giving my impressions. If anyone is interested, I could post my impressions of other mathematical books I read.

To build a solid foundation in proofs, I will now go through one or two books about mathematical proofs. Fred Conrad rated it really liked it Jan 14, Chapters In general, if the book doesn’t offer you enough explanation on a subject, search the Internet.

I thfory one of the first people to vote this answer, and I do agree with what you wrote there. Functions Halmos is using some dated terminology and is in my eyes a bit inconsistent here. There is a Wikipedia article about this: Axiom of choice The axiom of choice lets you, from any collection of non-empty sets, select an element from every set in the collection.

Naive Set Theory (book) – Wikipedia

But then again I am not really a math person. The continuum hypothesis had not yet been proven unprovable in ZFC. I’ve long believed that math is a poor and inconsistent language. Sometimes, I read other sources even before reading the chapter in the book.


Group theory and information theory come to mind, if you’re looking for a good time. Start off by trying to understand “propositional logic” aka “boolean logic”. None of the concepts within were particularly surprising, but it was good to play with them first-hand. Sign up or teory in Sign up using Google.

It’s used for extending counting beyond w. Conversational and light hearted, it makes learning of the basics of set theory a joy.

Naive Set Theory

Don’t get me wrong about that. There was little exploration of each axiom, what it cost and what it bought, and what alternate forms are available. To ask other readers questions about Naive Set Theoryplease sign up.

Man, even though I’m hardly disciplined enough to put fuel in my car, I’m still head over heels with rigorous Mathematics and Sets.

The exercises are useful too. I rushed through and missed a lot of subtleties.
