I&#x27;d argue that the memory of a smell is as visceral as the memory of a color or sound, which is not very.<p>The difference is that smell is so much more powerful in reality that we see through the memory-representation for what it is, an empty placeholder.  When we smell fresh bacon in the morning, that experience can be all-encompassing. The same is not true for the optical experience of the thing.<p>With colors and sounds we are merely less aware of the qualitative emptiness of their mental objects.
