What is it that makes us human, yet makes each of us different? Joyce Kloc McClure offers three defining features-we are all finite (limited), contingent (dependent), and free. McClure explains that finitude and contingency are common to all humans, but are also the two characteristics that create differences among us. We make ethical decisions based on our own distinct natures. Finite, Contingent, and Free is a Roman Catholic perspective on ethics written for everyone, not just Roman Catholics. McClure develops an ethical framework for the finite, contingent, and free human being. We begin with self-acceptance-understanding that our reactions to finitude and contingency contribute heavily to who we are. McClure says we then extend that same acceptance to others, making acceptance the proper response to the conditions of human existence, and the foundation for ethics.
