Preoccupied mostly with epistemological and metaphysical issues, and their implications for scientific and socio-political theories, Popper did not set out to construct a normative ethical theory defining right and wrong, as one finds in the works of modern or postmodern² moral philosophers such as Kant, J.S. Mill, or W. D. Ross. The closest he comes to formulating an ethical theory is speaking in favor of Negative Utilitarianism as opposed to Positive Utilitarianism.³
