  Since the difference between ‘Socrates’ and ‘wise’ turns out to be subjective in this way, it tells us nothing about the objective classification of the constituents of atomic facts. Moreover, Ramsey continued, once we are explicit about the wide and narrow scope occurrences of atomic expressions, there is no reason to think that any of them are especially incomplete. Ramsey held that it is only the ‘biassed interest’ of mathematicians, i.e. their extensionalism, that make things appear otherwise (1925b, 416). They neglect to distinguish between complex predicates which really do require variables for their depiction (\(xRa \lor xSb\)) and atomic expressions which don’t (‘\(f\)’ in ‘\(fa\)’), because they are only interested in the extensional matter whether these expressions are true or false of the same things. But to avoid ‘useless complication’ mathematicians treat the latter terms as requiring variables for their representation too (‘\(fx\)’), hence producing the appearance that there is some class of atomic terms which are incomplete because they require variables (1925b, 414–5). But, Ramsey continued, if it were not for the biased interests of the mathematician, we would allow ‘\(f\)’ to stand alone, so removing the appearance of an especially incomplete class of atomic terms.
