The underlying principle, throughout Sequential Problem Solving, is an obligation to help each other as citizens of a world community, and an acknowledgement that our real enemy is often ourselves. Our common problem is understanding ourselves in order to be a friend to others. Sequential Problem Solving provides us with a way of checking for the kindness factor in problem solving, with the goal of helping others and being a good citizen in the world community. A separate section, Dealing with Unattached People, is devoted to the problem of neighbors in the world community who are untrustworthy for some period of time, from the view point that today's enemies are tomorrow's friends. Some neighbors in the world community are, from time to time, untrustworthy. Since opportunities for misunderstanding are greater in a climate of mistrust, later sections are included that deal with mistrust and ways that we can gauge interpersonal situations and select an appropriate leadership style to match it. Sequential Problem Solving begins with the mechanics of learning and the role of memorization in learning. The techniques of effective memorization follow, as well as other important learning skills. This book contains many step by step checklists, much like pilots use to make certain that things of importance are not overlooked. These individual checklists are tied together in a broad flowchart that provides a sequential decision making pathway. The contents of the checklists are things that many adults utilize instinctively, without conscious thought. However these checklist can provide adults with a more positive way of checking their own thinking, in times of stress, and a way for students to become instinctive users of sound logic practices. Teachers may find that students instantaneously begin to act more mature because of the realization that their peers have a common body of knowledge about values and character traits and checklists to evaluate the behavior of others. For teachers, the sequence of presentation here can be readily altered to suit the teachable moment, that moment when a unique, high interest situation arises that lends itself to discussion of a particular topic. The sequence presented here is merely one way in which the various interlocking subjects can be presented. This presentation is intentionally concise to provide the reader with a composite picture of the use of checklists in logical thinking, without burdening the reader with statistical findings or repetitious historical background information. The ideas presented here are referenced to credible academic research wherever possible. Endnotes are used extensively to direct the reader to in-depth authoritative resources, and additional references are provided for each section at the back of the book.
