Unlike the history of, say, theology, the history of philosophy does not proceed from the primitive and inadequate to the more refined and improved. Important and stirring ideas and theories are found throughout the history of philosophy, from the Ancient Greeks to the present. The history of philosophy provides us with a wealth of sources for understanding God, humankind, and the world in our own time. You should also acquire greater ability in discerning the difference between arguments and mere claims, and an acquired respect for doing justice to the thinking of others. Logic is the science of reasoning.
Logic is the anatomy of thought.
It is a skill to be acquired. It has relation and applications to mathematics and to computer science. In everyday discourse, it is crucial to the criticism of claims made by advertisers, politicians, preachers, and journalists. Likewise, we wonder about the grounds of moral obligation, the nature of religious belief, the right order for society. These areas become fields of philosophic concern because they are fields of human concern.
