"The Knowledge of the Past and the Future" is a logical knowledge series about human existence, meant virtually to equip one with every logical tool necessary that is bound to make one to attain a good success. It does not only reveal that every success is not a good one but also what one has to do in order to be exceedingly successful. The author further reveals and explains one of the primary causes of people's lack of a good success, saying that they do not have a logicality thinking ability enough to understand the human existence, in general, and how an existence, in particular, is bound to live in life. In other words, a great many individuals are so ignorant of who they are, what the human existence entails, and how they should conceive living that they now end up struggling to live a successful life. Overall, it unveils how greatly one's past and one's future must agree with each other in an abiding and/or constant coalition, for one's existence to bring forth productiveness and a good, everlasting success.
