What is moral progress? Are we striving for moral progress when we seek to 'make the world a better place'? What connects the different ways in which moral agents, their actions, and the world can become morally better? This book proposes an explication of the abstract concept of moral progress and explores its relation to our moral lives. Integrating the perspectives of rival normative theories, it draws a clear distinction between ethical and moral progress and makes the case that moral progress can neither happen merely in theory, nor come about by a fluke. Still, the ideal of moral progress as a deliberate improvement in practices with a positive impact on the world is but one of several types of moral progress, relating in different ways to the theoretical and practical capacities of moral agents. No elevated level of sophistication in these capacities is required for moral progress to be possible, and the abstract idea of moral progress need not be on moral agents' minds in the pursuit of the morally better. However, a desire for impactful moral progress, far from being a moral fetish, marks a particularly valuable moral outlook.

The project examines the reasons for the many philosophical difficulties, and the failures, that Nietzsche sensed when he had concluded The Birth of Tragedy. The subsequent philosophical decision he made, on the way to reconceiving the classical ideas of tragedy, destiny, and martyrdom, allowed him to begin to conceive of what he would identify as a thinking devoted to affirmation. Everything he commits himself to writing after 1872, including the unpublished notes on myth from the Philosophenbuch, is a response to the disillusionment of his belief in Dionysos and the false promise of tragic affirmation. The Greek god had become a problem and an obstacle. Sustaining him, as a philosophical idea, was going to prove to be highly mixed; the struggle would become relentless. The Greek god is, in many ways, impossible to believe in as an ideal, in antiquity or for the present; and for a specific reason: the connection between the institution of the Dionysian festival and the religious ritual of sacrifice could not be ignored by Nietzsche. His sense of a "Dionysian nausea" has been overlooked. Tragedy and sacrifice are a binding relation in the Greek polis. Nietzsche seems to recognize the fact and commits himself to directly confronting the tragedy/sacrifice relation in all his subsequent works and with the intent on being a unique, individual resource for the truth of his self-revelations. He identifies himself with a new conception of the martyr (the witness) in order to provide an alternative to the classical martyr as the victim of violence and death and who, moreover, is executed by the state. Socrates and Jesus are omni-present for him. Nietzsche presents himself as new world-historical alternative and the self-revelations of a witness for the individuals he will often call (especially in Thus Spoke Zarathustra) his friends and neighbours and disciples. Is the whole of his philosophical enterprise successful? Do his self-revelations lead to the creation of the free spirit and therefore give him some assurance about the future of his legacy? Or does his commitment to the eternal recurrence, for example, lead him to a terrible realization? The study presents the force of Nietzsche's thought as he created the resources, which he hoped could be effectively transferred to a reader, to begin to create an affirmative reality he defines from out of the fullness of the free spirit and the philosopher.
