The Logic of Chance

In reading John Venn’s The Logic of Chance, one is struck by two things almost from the outset:

1. The English language, as it is used to describe mathematics, has undergone some changes since 1888 when this book first appeared.
2. Venn was a master of written English (and definitely much more than “that diagram guy”).

That having been said, this is not a book from which one could reasonably expect to learn the basic principles of probability theory. The prose is dense and only rewards very careful reading.

But it does so remarkably well. Indeed, at many points in the book, I felt a certain “thrill of discovery” after puzzling out what Venn was describing and connecting it back to something I knew well. For example, the treatment of the Law of Large Numbers is far removed from the compact description found in modern texts, but after careful re-reading, one appreciates encountering this old friend in old language.

Part of the appeal of this approach is a scarcity of equations. Certainly the text would pass any reasonable standard of mathematical rigor, but the explanation of the fundamental principles of probability is accomplished through careful exposition rather than a flood of mathematical notation. In that aspect, this historically significant work is at the same time a refreshing look at its subject.
