CHAPTER ONE
1.0  GENERAL INTRODUCTION
The problem of good and evil in the world of ours has become questionable. Good and evil without doubt have constituted lots of discomfort, havoc and other problems in human life. Consequently, so many thinkers of different epochs have contributed in one way or the other according to their own understanding, to unravel this dilemma. Nevertheless, throughout the different periods starting from ancient era to contemporary era, the problem of good and evil have continued to occupy the minds of philosophers. Even at that, no consensus has been reached with regard to a solution.  
Moreover, it may interest us to know that in this write up, we are to witness how Spinoza scrupulously did not delve into good and evil from the same perspective with others. His rigorous experiences of the retrospection on the previous philosophers on this topic allured him to conceive good and evil as being subjective.
Hence, this solves the numerous problems of some questions people do ask: whether there should be evil in the world created by all-powerful, all-knowing and all-merciful God. He thus based his conception of good and evil on individual differences: “Everyone, therefore, according to his particular emotions, judges or estimates what is good and what is evil.”1  This implies that what is good for one person may be evil for another. In fact, the problem of good and evil in the morality of Spinoza can be summarized with one of the popular dictums, which says, “One man’s protein is another man’s poison”. Hence, Spinoza’s good and evil should provide solution to the aged problem of good and evil which when mentioned remains fresh as can be seen in the work of Joseph Eno Inah who said “The problem of good and evil whenever mentioned, remains fresh and alive despite the fact that it started long ago.”2 The problem at stake has continued to remain a mystery as ever.
