Consider the following argument: "The listener should often be shown the conclusion contained in the principle. From this principle, as from the center, light shines on all parts of the work. In much the same way, a painter plans his painting so that light emanates naturally from a single source to each object. The whole work is unified and reduced to a single proposition enlightened in various ways." Rewrite the argument using the premise- conclusion model (Weston) and state if this is a strong or weak argument. Why/ why not? What type of argument is it?
