Document Summary

Theories of meaning: reference theory of meaning. Meaning of word is what is refers to (overall class) Ex. dog = all the dogs in the world. Falsification: confusion between understanding the meaning of the word/having the knowledge of what it refers to: certain phrases/words in which the reference is unknown. No reference class : idea theory of meaning. Our mental image cannot encapsulate all the characteristics of a dog: oldest man in the world yes, mental image, unless, yes, etc makes no sense, meaning as use.
