Synthesized answer
The author provides evidence in the description of the title, "On Lisp," which references the concept of solving programming problems by creating a problem-specific language built on top of Lisp using macros. This approach is described as "bottom-up programming" [1].
Further evidence is presented in the book's reputation for offering a complete description of Common Lisp macros and their applications. Additionally, the book explores other facets of bottom-up programming within Common Lisp [1]. The passages do not detail the specific types of evidence beyond these descriptions of the book's content and approach.

From the book
Title: On LISP by Paul Graham Description: The title itself, "On Lisp", is a reference to the idea that you can solve a programming problem by first building a programming language that lets you talk about your programming problem easier. In Lisp the programmer builds this problem specific language on top of Lisp itself using basic Lisp constructs called "macros". This style of programming is called "bottom-up programming". On Lisp is especially known for the complete description of Common Lisp macros and their uses, but the book also covers many other aspects of bottom-up programming in…
