This volume is a collection of papers that highlights some recurring themes that have surfaced in the generative tradition in linguistics over the past 40 years. The volume is more than a historical take on a theoretical tradition; rather, it is also a "compass" pointing to exciting new empirical directions inspired by generative theory. In fact, the papers show a progression from core theoretical concerns to data-driven experimental investigation and can be divided roughly into two categories: those that follow a syntactic and theoretical course, and those that follow an experimental or applied path. Many of the papers revisit long-standing or recurring themes in the generative tradition, some of which seek experimental validation or refutation. The merger of theoretical and experimental concerns makes this volume stand out, but it is also forward looking in that it addresses the recent concerns of the creation and consumption of data across the discipline.
