"All religious authorities are concerned about the dangers of nuclear war. All politicians are concerned about the dangers of nuclear war. Therefore, all politicians are religious authorities." This argument is invalid because of two reasons. First it is an overgeneralization. How can someone actually say that all religious authorities are concerned about the dangers of nuclear war or all politicians are concerned about nuclear war? Has anyone polled all religious authorities or politicians? There can be a very few religious authorities that might think it will never happen, so there is no reason to be concerned about it, or there could also possibly be a small religious faction that believes that nuclear war will get rid of all the evil in the world and is God's way of cleansing the world. The same can be said for politicians. Maybe there are a few that would want to start a war because of their selfish motives. One can argue that there are politicians in Syria and Iran that would love to bomb the U.S and Israel. Nothing was said about the politician having to be from this country. The second reason is that it is an illogical conclusion. One can not say that just because politicians and religious authorities share the same concerns that they will become one in the same. They just share one interest. It takes more than caring about nuclear war to become a religious authority. Religious authorities must go through a process that usually takes years of religious education, and practice. There are certain instances, of course, where some politicians are religious authorities also; however that is not predicated on the fact that they share the same view on one certain issue.

“If the Social Security system is further weakened, the elderly will have to fear poverty. Therefore, if the Social Security system is not further weakened, the elderly will not have to fear poverty. This is an overgeneralization and an illogical conclusion. It is true that if the Social Security system is further weakened, the some of the elderly will have to fear poverty, but not all of the elderly. Some elderly people are very wealthy. Other elderly people have family members who have made arrangements to take care of them and their financial needs. Of course, there will be a lot of elderly that will fear poverty without the social security checks they would be receiving once a month. Because of these reasons the argument is an overgeneralization. The argument is also an illogical conclusion because some people regardless of their social security will still be in poverty. Some people do not have a significant work history to receive a lot of money from the social security department. According to the social security department website, the average check for a retired worker is $1,294 a month. (Office, 2014) According to the United States Government the poverty level for a family of one is $980.83. (Federal Register, 2015) What must be taken into consideration is that some recipients will be well below the average social security check, and some will be well above. Those that are well below the average will be in poverty if that is all they are receiving. This argument does not account for the elderly that will not even receive a social security. They will have to fear poverty regardless of how weak or strong the social security is.

“The anti-abortionists say that the fetus is human, but they have not proved it. Therefore, they have no reasonable basis for opposing abortion." This argument is invalid because of at least two reasons. The first reason it is not a valid argument is because it has been proven that the fetus is human after eight months. How could it not be human if it comes from two persons who have intercourse...
