Alfred STERN, 1962: Philosophy of History and the Problem of Values, 's-Gravenhage [=The Hague, the Netherlands]: Mouton & Co.
The fact that men do accept and always have accepted their human condition is, in my opinion, the expression of certain fundamental evaluations, common to all men, of all civilizations, of all historical epochs and all social habitats. [p. 199]
It is that which I call the project of living common to all men of all ages, all civilizations, all social habitats. [p. 200]
Besides the different moralities required by the diversity of human projects, there is, however, one morality conditioned by the only project common to all men: that of facing the human condition, the project of living without too much suffering. The code of values derived from the universal human project of living constitutes basic human ethics. As we know, this human project of living is due to the positive evaluation of life and health by all men of all times, all civilizations and all social habitats. [p. 212]
... This supra-historical standard allows us to condemn with transhistorical validity all attacks against the only supra-historical values: human life and health, and the objective conditions necessary for their preservation on earth. [p. 213]
