"There are no universal truths for human happiness and behaviour." That's pretty bold statement. We know that there are universal truths to human suffering, and the behavior that can lead to suffering. We see it all the time depicted on the news, or we all experience it at one point or another. Why do you say the same is not true of happiness?

Even suffering is not universal. There are many groups who have overcome their subjective pain and no longer feel it.

We don't all suffer (but in the practical sense we do).
