When faith in an ultimate security is couched in symbolic expressions which suggest protection from all immediate perils , it is easy to be tempted to the illusion that the child of God will be accorded special protection from the capricious forces of the natural world or special immunity from the vindictive passions of angry men . Treating this paradox as willfully idiosyncratic , Vlastos insists that no one who heard Socrates would remain in doubt that he alludes to his own elenchus when speaking of an art whose exercise improves the moral fiber of his fellow citizens . When everybody at an institution is a licensed user , publishers can be relaxed about local re-distribution of materials after they are received from the publisher . Confounding arises when part of an observed association between two variables of interest can be attributed to the effect of a third variable not included in the analysis ( e.g ., the relationship between ethnicity and rates of child maltreatment may be confounded by differences in income ) . Whether this is because they do n't want to get out ahead of the administration ( an especially craven but typical attitude for GOP legislators when somebody with an " R " behind his name occupies the Oval Office ) or because they want to maintain a semblance of credibility when it comes to being for limited government ( while undermining it with almost every vote , especially on budget matters ) I do not claim to know .
