<Li> Sociologist William Graham Sumner finds it a fact that "everywhere one meets "fraud, corruption, ignorance, selfishness, and all the other vices of human nature". He enumerates "the vices and passions of human nature" as "cupidity, lust, vindictiveness, ambition, and vanity". Sumner finds such human nature to be universal: in all people, in all places, and in all stations in society . </Li> <Li> Psychiatrist Thomas Anthony Harris, MD, on the basis of his "data at hand", observes "sin, or badness, or evil, or' human nature', whatever we call the flaw in our species, is apparent in every person". Harris calls this condition "intrinsic badness" or "original sin". </Li> <P> Empirical discussion questioning the genetic exclusivity of such an intrinsic badness proposition is presented by researchers Elliott Sober and David Sloan Wilson . In their book, Unto Others: The Evolution and Psychology of Unselfish Behavior, they propose a theory of multilevel group selection in support of an inherent genetic "altruism" in opposition to the original sin exclusivity for human nature . </P> <P> Liberal theologians in the early 20th century described human nature as "basically good" needing only "proper training and education". But the above examples document the return to a "more realistic view" of human nature "as basically sinful and self - centered". Human nature needs "to be regenerated...to be able to live the unselfish life". </P>

Which of these is associated with the nature position concerning the explanation of human behavior
