Abstract

The fregean theory of meaning says how the meaningful parts of a meaningful expression contribute to that expression's sense and reference. But frege overlooks the fact that logical expressions play dual roles. The contributions of sentential connectives, For example, Are well described for contexts in which they connect sentences, But not for larger quantificational contexts. An obvious modification of the theory which might fill the abyss is considered, And it is maintained that it produces two difficulties: a replication of frege's concept 'horse' troubles and an infinite proliferation of logical vocabulary. The seriousness of these difficulties is briefly discussed
