The main criterion for human values, by which their hierarchy and importance are determined, should be some integrated supreme value embodying the "ideal life of humanity." Such is arguably the "complete well-being and flourishing of humanity."
Value is a property of a person, society, phenomena, and things, having important significance for a meaningful, safe, and comfortable human life, and broadly — for the "full well-being and flourishing of humanity" as the highest value in turn and the main measure of other values.
If we define the "complete well-being and flourishing of humanity" as the highest universal value of the human world, it must inherently encompass one of the most crucial spiritual ideas: "a reliable distant future."
The modern world will significantly approach solidarity when "complete well-being and flourishing of humanity" are sincerely recognized as the highest ideal by every nation.
