I wasn't able to find any specific authors, articles, or books that explicitly substitute the generic concept of "idea" with Spinoza's concept of "ingenium." However, I found some resources that discuss Spinoza's concept of "ingenium" and might help you understand the parallel between the two concepts:

1. "Spinoza: Practical Philosophy" by Gilles Deleuze: In this book, Deleuze discusses Spinoza's philosophy in detail, including the concept of ingenium. Deleuze is known for his unique interpretations of Spinoza's work, so this book might offer some insights into the parallel between "idea" and "ingenium."

2. "Spinoza's Ethics: An Introduction" by Steven Nadler: This book provides a comprehensive overview of Spinoza's Ethics, including discussions on various key concepts such as ingenium. It may help you understand the relation between Spinoza's concept of ingenium and the generic concept of an idea.

3. "Spinoza and the Stoics" by Firmin DeBrabander: This article, published in the journal Philosophy Today, explores the influence of Stoic philosophy on Spinoza's work, including the concept of ingenium. It might help you understand the connection between the two ideas in the context of Stoic philosophy.

While these resources may not directly substitute the concept of "idea" with "ingenium," they might offer insights into the parallels between the two concepts and help you understand Spinoza's perspective on the matter.
