Sample Book Insights:
#1 Reasoning is the process of making sense. It is the science of correct reasoning, and some would call it a discipline of the mind. With study, observation, and practice, we can acquire that mental discipline to use logic to persuade and convince others effectively.
#2 The law of non-contradiction states that contradictory propositions cannot be true at the same time and in the same sense. When two propositions can co-exist, they are not contradictory and do not violate the law of non-contradiction.
#3 The fourth law is that for every unexplained fact, a rational mind will seek the reason behind it. A rational mind will not accept any reason that is not sufficient. In the example, the explanation must answer questions like: Why did the stranger want to sell it so quickly. Why at such a low price.
#4 An appreciation of logic requires an understanding of the following concepts: claims, inference, and arguments. While proponents use arguments to persuade others, not all arguments are validly structured. Critical thinking is required to recognize and construct valid and sound arguments.
