The concept of human dignity, despite its growing importance in legal texts and declarations in the last decades, is notoriously contested in moral philosophy and legal theory. There is no agreement either on what human dignity is or whether one should care much about it. We will show how these questions could be answered given the assumption that the expression ‘human dignity’ is to be read literally, as dignity of humans, where ‘dignity’ is understood as dignity proper, i.e. dignity as it is usually ascribed outside of legal contexts. Dignity proper has played an important role in the history of mankind. It is sometimes also called ‘social dignity’ because it is bound to social relations, or ‘contingent dignity’, on the assumption that having dignity proper is due to contingencies of life and one's own behaviour (in contrast to human dignity as an essential feature of humankind). Dignity proper therefore depends on being treated with respect by others and on being able to present oneself as being of equal dignity in various practical contexts.

Dignity proper is part of an extended conceptual space of evaluative terms which are important in moral life, including, among others, decency, nobility, rank, honour, respect, esteem, grace, decorum, merit, self-respect, coolness, offence, humiliation, degradation, shame. It is obvious, historically, that the concept of dignity proper must have played some role in the development of the concept of human dignity.
