Mackie, in his article Evil and Omnipotence, constructs an argument against the idea of ​​the possibility of an existing God who exhibits the characteristics defined by the main religions: Christianity, Islam and Judaism. . These characteristics include that God is omnipotent, or is able to stop evil, and omnibenevolent, or is willing to eliminate evil and is entirely good. Mackie systematically reviews 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 exist. This is one of the most popular arguments in favor of atheism. Mackie wishes to refute the existence of God, or at least the view that God is both omnipotent and entirely good, through an argument that uses the problem of the existence of evil. Here is how he states his argument: 1. Suppose there is a God composed of the above characteristics. 2. If this God is all-powerful, then there is no limit to his ability or what he can do. 3. If this God is entirely good, then one would assume that He would want to eliminate evil completely. 4. If there was a God who knew evil existed, could eliminate it, and wanted to eliminate it, then it would make sense that there would be no evil. 5. However, evil exists. 6. Therefore, an all-powerful and all-good God cannot exist. This argument is analogous to, say, that of a master chef, in the sense that this chef is capable of cooking only the tastiest dishes in the world, he is capable of cooking that way all the time, and he knows that people only like good food. . However, in this chef's restaurant, there always seems to be dishes in poor taste. But if the chef was able to cook the tastiest dishes at all times and if he knew that people only wanted tasteful dishes, then we would have to assume that this type of chef could not exist. Again, Mackie's argument is not against the existence of God, but against the existence of a God who is composed of the characteristics of being all-powerful and totally good. In his article, Mackie not only lays out his own arguments for atheism, but he also refutes any arguments that might be contrary to his own..
