A book titled for this concept argues that one form of it dominates outer and inner nature through the process of “desubstantialization.” That book critiques the subjective form of this concept for prioritizing self-preservation. Those ideas from Max Horkheimer’s book titled for the “Eclipse” of this concept are expanded on in Dialectic of (10[1])Enlightenment, which argues the title movement led to this concept’s instrumental form enabling Nazi oppression. A 1781 book argues that this title concept is the source of transcendental ideas independent of the senses; that book analyzing a form of this process argues that the (10[1])Ding an sich (“ding ahn ZISH”) is unknowable and cites the formula 7 + 5 = 12 to argue for synthetic a priori truths. For 10 points, name this concept whose Practical and Pure forms were critiqued (10[1])by Kant. ■END■
