Abstract
From the day on which humans are born they need things. Some of these needs seem “basic,” such as our needs for food, water or shelter. Everybody has these needs. We cannot escape them. We also cannot escape the serious harm that arises when these needs remain unsatisfied. It is thus no wonder that in thinking about what we ought to do some researchers have suggested to first and foremost focus on people's basic needs. Such need‐based theories must answer three main questions: What are basic needs? What are their implications for normative questions? And how can these needs and their satisfaction be measured? Proponents must also defend these theories against objections, such as against the objections that the theories are paternalistic, materialistic, and passivity‐promoting. Depending on their goals and contexts (distributive justice, sustainable development, human rights, etc.), appeals to basic needs may take various different forms.
