  Physical structures of the rose in front of me—the anther in the rose's stamen—produce pollen, which has a certain molecular composition that results in my sensation of its odor. Other molecules in the petals of the rose reflect light at a certain wavelength which in turn causes in me a certain characteristic visual sensation of red. If I am speaking correctly when I say “That rose smells good”, I am reporting the fact that I conceive of the rose as possessing a particular relational property: I am aware that the rose has the property of being-such-as-to-cause-in-me-sensations-of-a-sweet-smelling-odor. Ultimately, the rose possesses this relational property because of facts about its molecular structure that account for its producing this odor in a certain way, and facts about me that account for the fact that these pollen molecules enter my nasal cavity, eventually reaching the olfactory bulb, and cause certain sensations in my mind. But when I am aware of the odor of the rose, I am aware of none of that; I am aware only of the fact that there is something about the rose that makes it cause in me certain sensations in normal conditions.
