Principles of the Deliberative Ought

Practical reasoning aims to answer the question “What ought I to do?”. This research project is concerned with the concept of ‘ought’ that figures in this core question of practical deliberation and may thus be called the deliberative ought. The goal of the project is to systematically examine fundamental principles of the deliberative ought and their philosophical implications, where a principle is assumed to be fundamental if its claim to validity does not depend on any substantive normative theory. Fundamental principles of the deliberative ought include e.g. principles that correspond to the laws of deontic logic and the so-called instrumental transmission principles.
