The pragmatic approach is motivated by the view that the nature of an argument cannot be completely captured in terms of its structure. In contrast to structural definitions of arguments, pragmatic definitions appeal to the function of arguments. Different accounts of the purposes arguments serve generate different pragmatic definitions of arguments. The following pragmatic definition appeals to the use of arguments as tools of rational persuasion (for definitions of argument that make such an appeal, see Johnson 2000, p. 168; Walton 1996, p. 18ff; Hitchcock 2007, )
Embryonic stem cell research has been in the controversial focus for many years and has gathered a lot of opposition to stem cell research from the public and religious groups. Some believe that there’s a lot of potential in the embryonic stem cell research as only this cell has the flexibility for repairing damaged nerves, organs and tissues, and curing hundreds of deadly diseases. On the other hand, a lot of people defend their arguments against stem cell research and believe it’s highly unethical and even murderous to destroy a human embryo for a faint possibility of finding a cure or helping someone in need.
