Chapter 15 Concept

One concept from the assigned reading that I found useful/interesting was using reasoning effectively. There are four types of reasoning such as deductive, inductive, causal, and analogical. Deductive reasoning is from general principle to specific case. The strength is that it relies on established formal logic, but the weakness is invalid premises leading to false conclusions. Inductive reasoning is from specific examples to general principle. The strength is that you visualize and personalize the argument, but the weakness is the lack of representation, sufficiency, and relevance. Causal reasoning is one event causes another. The strength is it’s useful for explanation and prediction, but the weakness is the incorrect cause-effect link. Lastly, there’s analogical reasoning which draws similarities between two distinct cases. The strength is that it links the unfamiliar with the familiar, but the weakness is the key differences are ignored.
