Tucker, Chris, 'Modeling Requirement for Any Number of Options', The Weight of Reasons: A Framework for Ethics (New York, NY , 2025; online edn, Oxford Academic, 13 Jan. 2025), https://doi.org/10.1093/9780197786956.003.0014, accessed 4 May 2025.
Abstract
This is the last and least chapter, but it completes the narrative of the book by identifying the fundamental model (Dynamic Scale), explaining why Dual Scale is not the fundamental model (it has difficulty detecting exotic kinds of dilemmas), and why it should be used anyway (it has the best balance of reliability and ease of use). At the heart of this chapter is the attempt to minimize the computational complexity of calculating which, if any, option is required when there are more than just a few options. Along the way, it also further defends contrastivism and explains how it is different from holism.
