Here is a pdf of the third addition of Against Method -- Against Method
I would suggest reading from page 5 to 23. This would include the Analytical Index, the Introduction, and the first two chapters. If you've got the time, the Preface, the Preface to the Third Edition, and the Introduction to the Chinese Edition are also worth a read; they give you a view into Feyerabend's larger project, and boy is he an interesting character.
