Hartmann’s ethics is a comprehensive synthesis that combines elements of taste and feeling with principles of reason and combines them into an evolution of ethical thinking. This is finally crowned by a metaphysical interpretation of the unity and the finality of all living beings, which establishes a universal moral commitment. Hartmann takes over the ideas of Schopenhauer, Hegel, Schelling and Darwinism and is one of the striking epigones of classic German philosophy that open to the development of modern science and deal with ethics with great clarity and foresight for the wealth of moral perspectives. He represents a post-Christian pantheism, which is only the keystone, not the quite empirical starting point of his ethics. With his work he also profiled himself as an antipode of radical subjectivism and nihilism by Stirner and Nietzsche and showed the way to the development of a material ethics by Scheler.
