Now, attempting to design an original constitution may suffer from the same contests facing any account of originalism. Different originalists make different commitments, and any attempt to select among them will be vulnerable to criticism. Despite differences between originalists, three commands and commitments can fairly be attributed to originalism without raising too much contest: the original constitution is written at the founding and changed only by the amendment procedure it sets out, is law insofar as it provides rule-like prescriptions, and occupies a delimited domain, leaving the rest to democratic activity. The model of an original constitution here elaborated seeks to provide a model of a fictional constitution that satisfies, perhaps to a fault, the key commitments and commands of originalism. It seeks to bring to light the commands and commitments originalism would have of us, and of constitutions
