Problem: Give my class mate a positive review of the writing Thesis Natural law theory provides a stronger foundation than existentialism for explaining why people have objective duties toward vulnerable individuals. However, existentialism reveals an important weakness in natural law theory by showing that appeals to human nature can become restrictive when society uses them to assign people fixed identities or roles. Argument The greatest strength of natural law theory is that it does not allow personal preference to erase another person's dignity or needs. If moral duties depended entirely on the values each individual chose, a person could reject responsibility whenever it became inconvenient. A parent might decide that career achievement, freedom, or personal fulfillment mattered more than remaining emotionally present for a child. Natural law theory challenges that reasoning because caring for human life, development, and relationships is not merely one optional lifestyle among many. Need Assignment Help?
