 A schema-template is a string type having indefinitely many tokens in Peirce’s sense (Peirce 1906; Corcoran et al. 1974: 638 n. 5). But none of the tokens of a schema-template are instances of the schema. In fact, every instance of a schema is a string type having its own tokens. The word ‘instance’ is a relation noun for a relation certain string types bear to certain schemas. The word ‘token’ is a relation noun for a relation certain macroscopic physical objects bear to certain abstract objects. Neither a schema nor a schema-template is a common noun denoting the instances, and neither is a proper name of a set of instances.
