Some say that entrophy is merely a measuring system, a measure of disparity, chaos, deterioration, and so cannot have an opposite. If we agree to this then attraction can be said to be a measure of attractiveness, or gravily in the broader sense of the word.
That would mean that attraction and entropy are two seperate tendencies that have opposite effects, but are not polar opposites, as poles must always be directly linked in some way. Hence, one may have high levels of attraction at the same time as we have high levels of entrophy, or any other imaginable combination. If they were polar opposites then higher entrophy would invariably mean lower attraction and visa versa..
