Tehran University of Medical Sciences Iranian Journal of Public Health 2251-6085 37 Supple 1 2008 03 15 28 30 K Aramesh 2015 10 03 My main question in this article is as follows: "to which extent cultural diversity should be permitted to influence bio-ethical judgments?" There are cultural heritages, values and traditions which are acceptable and respectable and there are ones which are not so. In this article I concluded that our reasoning based on common ethical sense can guide us through such differentiations. Human dignity as a common notion among most alive cultures and religions thorough the world, can be relied for sketching a plan for further dialogues in this regard. https://ijph.tums.ac.ir/index.php/ijph/article/view/2887 https://ijph.tums.ac.ir/index.php/ijph/article/download/2887/6182
