The post–Kantian idea of a system demands complete intelligibility, taking systematicity all the way. Many would prefer more moderate or balanced forms of philosophy, indifferent to this ‘nothing–halfway’ idea of a system. But I argue that post–Kantian reasons for the importance of their idea are surprisingly strong. Some at the time advance what I call ‘system–critique’: defending the idea’s importance while yet rejecting systems. Jacobi is a paradigm, influencing Kierkegaard and later system–critique. He shows that reasons for the idea’s importance are not contingent on defense or acceptance of a system—and are stronger for this independence. Such reasons are shared with post–Kantians taking a more positive view of systems, as in Schelling’s ‘Vom Ich’. So there are surprisingly strong reasons to prefer both nothing–halfway system–critique and system–building over more moderate, balanced, or indifferentist philosophy.
