Although Hume, regarding his basic ideas, explicitly identifies beauty as a sentiment, but in some passages it is introduced not as a sentiment but as a real quality. In some other passages, it also seemed like a secondary quality. Some interpreters, just by referring to these unclear passages in Hume’s writings, offered a kind of interpretations from Hume’s basic idea of beauty that finally is incompatible with his entire philosophy. We attempt, in this paper, by presenting the Hume’s theory of beauty as sentiment and its different from the making -beauty qualities, to explain the reasons of these misinterpretations.
