Philosophers can often be classified in terms of their favorite parts of speech: there are those who believe that nouns designate the only reliable aspects of being; others, of a contrary view, who see those nouns as simply unkempt nests of qualities; and all are familiar with the Heraclitean people who embrace verbs as if you could make love to water while entirely on land. I have personally always preferred prepositions, particularly of, and especially, among its many meanings, those of possession and being possessed, of belonging and exclusion.
