Concept

A fallacy of composition occurs when a property of each member or part is inferred to belong to the group or whole. A fallacy of division makes the reverse move, from the whole to its parts.

Application

The premise assigns light weight to every machine part, and the conclusion transfers that property to the entire machine. The inference therefore moves from parts to whole.

Contrast

• Composition: part-level properties are projected onto the whole.

• Division: a whole-level property is projected onto the parts.

• Accent: meaning is distorted through misleading emphasis.

• Amphiboly: ambiguity arises from grammatical structure.

Result

Therefore, the argument commits the fallacy of composition.
