The interest in "social sustainability" has recently increased in the field of urban development. We want societies, cities, and neighborhoods to be economically and environmentally sustainable, but we also want urban areas that are safe, diverse, walkable, and relaxing, just to mention a few examples. Strikingly, however, there is no consensus regarding what definition of "social sustainability" should be employed. Additionally, some people are skeptical about the prospect of finding a useful definition at all and claim it is impossible to satisfactorily define the concept for various reasons, such as its complexity. A potential first step towards navigating this conceptual maze is to provide desiderata for a definition of social sustainability. We defend a list of nine desiderata and thereby create a theoretical framework for analyzing and constructing a definition of "social sustainability". We also examine the skeptical arguments and find that it is premature to conclude that the goal of finding a useful definition is hopeless. With the criteria in place, the future debate can proceed by assessing definitions of "social sustainability" in a more structured and transparent manner. This activity is of upmost importance if we want to create just cities. Keywords: Social Sustainability, Definition, Purposes and Aims, Conditions of Adequacy

This article defends the Harm Principle, commonly attributed to John Stuart Mill, against recent criticism. Some philosophers think that this principle should be rejected, because of severe difficulties with finding an account of harm to plug into it. I examine the criticism and find it unforceful. Finally, I identify a faulty assumption behind this type of criticism, namely that the Harm Principle is plausible only if there is a full-blown, and problem-free, account of harm, which proponents of the principle can refer to.

An important objection to the Counterfactual Comparative Account (CCA) of harm is that the account fails to cohere with standard views about the normative significance of harm. In response, some proponents of CCA suggest that the concept of harm should play a more limited role in normative theorising than philosophers might usually think. This paper addresses the most elaborate defence of CCA of this sort, namely that by Neil Feit (2019) Ethical Theory and Moral Practice, 22, 809-823, and argues that it is unsuccessful.
