 The challenge for the generative Essentialist adopting the FLN/FLB distinction as characterized by HCF is to identify empirical data that can support the hypothesis that the FLN “yields discrete infinity”. That will mean answering the question: discrete infinity of what? HCF write that FLN “takes a finite set of elements and yields a potentially infinite array of discrete expressions” (p. 1571), which makes it clear that there must be a recursive procedure in the mathematical sense, perhaps putting atomic elements such as words together to make internally complex elements like sentences (“array” should probably be understood as a misnomer for ‘set’). But then they say, somewhat mystifyingly:
