Mackie in his paper Evil and Omnipotence, constructs an argument against the idea of the possibility of a God existing that has the characteristics laid out by the main religions: Christianity, Islam, and Judaism. These characteristics include that God is omnipotent, or He is capable of stopping evil, and omni benevolent, or He wants to eliminate evil and He is entirely good. Mackie systematically goes through his logical thought process as well as his response to any type of criticism or alternative solution that might arise. The main point of his argument is to establish that God, as constructed by Christianity, Islam, and Judaism, could not possibly exist. It is one of the most highly regarded arguments towards atheism.
Mackie wishes to disprove the existence of God, or at least the view of God being both omnipotent and wholly good, through an argument which uses the problem of the existence of evil. Here is how he lays the argument out: 1. Suppose there is a God, whom is composed of the above characteristics. 2. If this God is omnipotent, then there is no limit to His ability or what He can do. 3. If this God is wholly good then it would be assumed that He would want to eliminate evil completely. 4. If there was a God who knew evil existed, could eliminate evil, and wanted to eliminate evil then it would make logical sense that there would be no evil. 5. However, evil does exist. 6. Therefore an omnipotent and wholly good God cannot exist. This argument is analogous, say, to a master chef, in that this chef is capable of cooking only the best tasting food in the world, he is able to cook this way all the time, and he knows that people only like good tasting food. However, in this chef's ...
