Commentary for “Understanding Consciousness Through Category Theory”

Abstract

 Tsuchiya & Saigo (2019) proposed the way of understanding consciousness based on category theory. In this commentary, I discussed four points about their article: 1.Validity of their treatment of the definition and model of consciousness, 2. Verifiability and novelty of their proposal using Yoneda lemma, 3. Lack of extensive review of consciousness studies, and 4. Readers' images and the unity of image.
