The interviewee has a different idea:<\/p><p>\u201cYou are neglecting the fact that abortion is murder. We should have laws against murder, and therefore we should have laws against abortion. \u00bb<\/p><p>The interviewee&#039;s argument is as follows:<\/p><p>Premise 1: Abortion is murder<\/p><p>Premise 2: We should have laws against murder<\/p><p>Conclusion: So we should have laws against abortion.<\/p><p>No one will argue with the need for laws against murder, but the real question here is whether abortion should be legal. The first premise therefore begs the question, as no evidence is provided to support this claim. This only assumes that abortion is murder. Which a priori has no relation to the initial problem.<\/p><p>Of course, someone who already agrees with the interviewee will see no problem in the reasoning, because they are already convinced that it is true.<\/p><p>However, whatever our own beliefs, there is a difference between believing something to be true and being able to justify it. In other words, there is a difference between the position itself and the arguments that support it.
