I'm interested in starting a phenomenology study group beginning with Husserl. I would want to start with Husserl's _Logical Investigation_s Volumes 1 and 2 but I was wondering if the abridged version "The Shorter Investigations" will be more than enough to understand Husserl. I would like to be able to study other phenomenologists, but if the abridged version will not do, then reading the full volumes will take up the whole time. In short, has anyone read both the abridged and unabridged _Investigations_, and if so, what are your suggestions? Thank you.
