Emotion in place of evidence
Emotions are a normal and legitimate part of human communication; the fallacy lies in substituting them for the reasons that should establish a conclusion. When an argument leans on making the audience afraid, sympathetic or indignant rather than on relevant facts, it commits an appeal to emotion. The feeling produced is psychologically persuasive but logically irrelevant: being moved to pity by a story does not, on its own, show that the conclusion drawn from it is correct. This is why logicians classify it as a fallacy of relevance.
Common sub-types
Several recognised fallacies are species of the appeal to emotion. Appeal to fear (argumentum ad metum, or scare tactics) pressures acceptance by threatening dire consequences. Appeal to pity (argumentum ad misericordiam) substitutes sympathy for evidence. Appeal to flattery and appeal to spite exploit pride and resentment respectively. Appeal to popularity and wishful thinking also draw their force from feeling rather than fact. In every case the structure is the same: an emotion is offered where a reason is required.
When emotion is legitimate
Appealing to emotion is not always fallacious. Emotions can be appropriate responses to genuine reasons — describing real suffering to motivate action that is independently justified, for instance. The fallacy occurs only when emotion stands in for the missing argument, or is used to distract from a lack of evidence. Effective and honest persuasion often engages emotion alongside sound reasoning; the test is whether removing the emotional content would leave a valid argument intact, or nothing at all.

Common misconceptions
What people often get wrong
Often heard: Any argument that makes you feel something is an appeal to emotion.
Actually: Emotion is a normal part of communication and is not fallacious in itself. The appeal to emotion fallacy occurs only when feeling is substituted for relevant evidence. An argument can be moving and sound at the same time.
Often heard: Appeal to pity is always a fallacy.
Actually: Pity is fallacious only when it replaces the reasons that should support a conclusion. Where compassion is itself a relevant consideration — for example, in deciding how to treat someone — invoking it can be appropriate rather than fallacious.
Often heard: A factual, evidence-based argument cannot also use emotion.
Actually: Honest persuasion frequently pairs genuine evidence with emotional engagement to motivate action. The fallacy is not the presence of emotion but its use as a substitute for reasons. Emotion alongside valid support is rhetoric, not fallacy.
