G. H. von Wright

G. H. von Wright was a philosopher known for his contributions to deontic logic, which is the study of logic concerning obligation, permission, and related concepts. He explored how we reason about what ought to be done, distinguishing between what is permissible and what is obligatory. His work helps us understand moral and legal reasoning by formalizing how we think about norms and duties. Von Wright's ideas are important in philosophy, computer science, and ethics, as they clarify how rules and obligations can be modeled and understood logically.
