Bertrand Russell, The Problems of Philosophy, in Great Books of the Western
Worl, V.55 (01)
''Speaking generally, adjectives and common nouns express qualities or
properties of single things, whereas prepositions and verbs tend to express
relations between two or more things. Thus the neglect of prepositions and
verbs led to belief that [every proposition] can be regarded as attributing
a property to a single thing, rather than [expressing a relation between two
or more things]''. ''...we can prove that there must be relations, i.e., the
sort of universals generally represented by verbs and prepositions''. ''it
seems plain that the relation subsists independently of our knowledge of
it''. p.272 (02)
