Unexpected Uncertainty in Adaptive Learning: A Wittgensteinian Study Case

Wittgenstein talks in his Philosophical Investigations of a pupil engaging in a repetitive series continuation who suddenly begins to apply a different rule than the one instructed to him. This hypothetical example has been interpreted by a number of philosophers to indicate either a skeptical attitude towards rules and their application, an implicit need of knowledge and understanding of a rule accessible to those engaged in a given practice, or a certain normativity that guides our actions but is not cognitive, but processual in nature. I wish to support and extend Ginsborg’s account of primitive normativity from a novel perspective in a twofold manner: 1) by describing the mechanism of primitive normativity via Kant’s concept of aesthetical and epistemic pleasure and displeasure; 2) by applying the conceptual pair of expected and unexpected uncertainty from adaptive learning theories, which describe the fluctuation of learning rates under uncertain circumstances.I am grateful to Dr. Romain Ligneul's help in better understanding the subtleties of this conceptual pair.
