Answer:
Morality is survival behavior above the individual level
Explanation:
Moral systems evolved among people as an aid to survival. Morality is survival behavior above the individual level.
Moral systems identify values and sort behaviors into good (virtues) and bad (vices) classes.
Moral systems prioritize values, sorting them in some order of importance.
Some moral systems work better than others in an absolute sense.
Some moral systems work better than others for particular groups of people, who find that the practice of certain moral systems aren't suited to their innate abilities and characteristics.
A proper moral system is a moral system that does what a moral system ought to do, namely, preserve the existence of the practitioner group.
In any proper moral system, the survival of the practitioner group is the highest value. Why? Because nothing matters to the dead. Because no other value - truth, justice, freedom, properity - has any value at all to extinct peoples. Because only to something alive may anything else be good.
Truth is always in second place in value, after survival. Why? Because all third values depend on truth, just as they <em>and truth</em> depend on survival. Unless you first know what the truth is, you can't possibly discover what justice is. Unless you first know what the truth is, you can't be certain that you really are free.
These third values aren't bad things. Justice and freedom, for example, are <em>good</em> things. They are values. But they aren't the <em>highest</em> values: truth outranks them both. And survival outranks even truth.
