The Minimalist Program has advanced a research program that builds the design of human language from conceptual necessity. Seminal proposals by Frampton & Gutmann (1999, 2000, 2002) introduced the notion that an ideal syntactic theory should be ยcrash-proofย. Such a version of the Minimalist Program (or any other linguistic theory) would not permit syntactic operations to produce structures that ยcrashย. There have, however, been some recent developments in Minimalism ย especially those that approach linguistic theory from a biolinguistic perspective (cf. Chomsky 2005 et seq.) ย that have called the pursuit of a ยcrash-proof grammarย into serious question. The papers in this volume take on the daunting challenge of defining exactly what a ยcrashย is and what a ยcrash-proof grammarย would look like, and of investigating whether or not the pursuit of a ยcrash-proof grammarย is biolinguistically appealing.
