“Accept or implement strategies witnessed by different societies for a very long time without considerable alteration.”
Any disproportionate/evil practice cannot be sustained for a very long period among several societies at the same time. (Here, “a very long time” means many generations, i.e. long enough for a practice to outlive the rulers, systems and fashions under which it began; “different societies” means societies that are far apart in place, language and belief, so that one has not simply copied it from another; and “without considerable alteration” means that the core of the practice stays the same, while its outer form, i.e. the customs and language, may differ from society to society.) (In practice, a practice passes this test when it is found in different societies, even in different forms, while its core survives for a long time and never fails.)
