Examining arguments from design › A discipline for testing an inference

The Dialogues supplies a useful sequence of questions for reading an argument from design. Identify the observed feature first. Then identify the proposed explanation and the experience or reasoning connecting them. Finally, list the attributes that the conclusion adds. A single appealing comparison should not make those additions invisible.

For example, an argument may begin with the adaptation of organisms and end with a claim about a morally perfect creator. The transition needs separate support. Explaining organization and establishing goodness are different tasks, even if one religious tradition assigns both to the same being. Hume's conversation repeatedly brings that distinction back into view.

The same discipline applies to criticisms. Showing that several designers remain possible does not establish several designers. Imagining material order does not establish its history. Criticizing the evidence for an infinitely good cause does not settle every religious question. Precision makes both the defense and the criticism harder to conduct carelessly.

Read Part II for the initial analogy, Part V for its theological consequences, and Parts X–XII for suffering and the final qualification. The central question is how far observations of the world can take us. Hume's speakers force us to say what has actually been inferred, what remains conjecture, and what would require another argument.
