This Concept Map, created with IHMC CmapTools, has information related to: modus ponens, Paul is a rational human being therefore (ArgScheme: modus ponens) Paul is responsible for what he did, if someone's fingerprints are on a mur- der weapon, then this is a sufficient condition for the fact that this person committed the murder therefore (ArgScheme: modus ponens) John committed the murder, John's fingerprints are on the murder weapon therefore (ArgScheme: modus ponens) it is false that if someone's fingerprints are on a mur- der weapon, then this is a sufficient condition for the fact that this person committed the murder, you will be admitted to medical school only if you have taken organic chemistry therefore (ArgScheme: modus ponens) you have taken orga- nic chemistry, John did not committ the murder therefore (ArgScheme: modus ponens) it is false that if someone's fingerprints are on a mur- der weapon, then this is a sufficient condition for the fact that this person committed the murder, p is a sufficient condition for q therefore (ArgScheme: modus ponens) q, you want to maintain a good reputation therefore (ArgScheme: modus ponens) give only honest advice, p only if q therefore (ArgScheme: modus ponens) q, give only honest advice if you want to maintain a good reputation therefore (ArgScheme: modus ponens) give only honest advice, utilitarian/ consequentialist/ pragmatic argu- ments can be represented as modus ponens example If the cost/benefit ratio for action A is lower than for action B, then action A is better, p unless q therefore (ArgScheme: modus ponens) p, if we assume that reflection shows that the alibi-argu- ment is more con- vincing than the other one, then the task is to figure out what is wrong with the original argument. In this situation it is possible to falsify the original inference rule, as in the following reformulation of the original argument. Of course, it is still possible that one of the premises of this argu- ment is wrong therefore (ArgScheme: modus ponens) it is false that if someone's fingerprints are on a mur- der weapon, then this is a sufficient condition for the fact that this person committed the murder, the ice will melt unless it remains cold therefore (ArgScheme: modus ponens) the ice will melt, p → q therefore (ArgScheme: modus ponens) q, hypothetical imperatives can be represented as modus ponens example give only honest advice if you want to maintain a good reputation, you study hard therefore (ArgScheme: modus ponens) you will excel in school, p is a necessary condition for q therefore (ArgScheme: modus ponens) p, q therefore (ArgScheme: modus ponens) p, John has a perfect alibi therefore (ArgScheme: modus ponens) John cannot be the murderer, p therefore (ArgScheme: modus ponens) q
