Final answer:
To identify implicit premises in a moral argument, analyze the reasoning and validity of the logic used, provisionally assume truth of premises, and consider the soundness of the argument.
Step-by-step explanation:
The best approach to identifying implicit premises in a moral argument is to treat the arguments as formal logical structures, analyzing the reasoning foundation of moral claims. This entails examining stated premises, considering types of evidence such as definitions, empirical evidence, and principles, and testing the validity of deductive and inductive inferences. By provisionally assuming the truth of the premises, we can test whether the conclusion logically follows. It is also crucial to consider potential exceptions, counterexamples, and to judge the argument's soundness by evaluating both its logical structure and the truth of its premises.
