This paper formally defines "neo-nostalgia" as a new genre of human expression — one that uses the formal structures of academic inquiry (DOI registration, peer review aspiration, citation practice, hypothesis formulation) to express content that is fundamentally personal, intuitive, and civilizationally motivated. The genre is distinguished from conventional academic writing by its explicit acknowledgment of the author's subjective position as constitutive of the inquiry, and from conventional memoir or personal essay by its insistence on formal rigor as an aesthetic commitment. The author's body of work — approximately 550 DOI-registered documents spanning astrophysics, economics, philosophy, and personal narrative — is proposed as the founding instance of this genre.
