I. Introduction
II. Main Issues in &quat;On Phases&quat;
1. Asymmetry in the contribution of &quat;language design&quat; of the two interface systems
2. Internal Merge as well as external Merge comes &quat;free.&quat;
3. No c-command relations; re-interpretation of Binding Theory
4. Formal features such as agreement, which trigger operations, are merged solely on phase heads, C, v. (This drastically reduces the set of possible grammars, thus simplifying the UG architecture.) Hence, IM should be driven only by phase heads.
5. A new perspective on islands
6. More on parallel movement
7. Phases
8. The issue of EPP/Edge-Feature: If a language lacks an expletive, the closest nounphrase raises to SPEC-T, sometimes with default agreement morphology (or null)on T (Lavine and Freidin (2002); Miyagawa (in press)).
