Under the standard interpretation of Horn-clauses (as in Prolog) a variable is implicitly universally quantified if it appears on the left hand side of a clause, but existentially quantified if it appears exclusively on the right hand side. The interesting fact is that the Horn-clause representations of the surface sentences are structurally as similar to each other as the surface sentences are, and they differ exactly in the same way the sentences do. The seemingly minor change from a intransitive verb phrase (\"he is happy\") to a transitive verb phrase referring to an element of the antecedent (\"he respects her\") turns an exi-.stential quantification (\"any man is happy if there ls a woman he loves\") into a universal quantification (\"any man respects any woman he happens to love\").

The meaning of \"to donate\" implies that the person donating something already has, or can easily get, whatever he donates; he does not have to wait for it to come his way. Equally, the meaning of the verb implies that it will be a trivial task to find a taker for the donation. The meaning of \"to defend\", on the other hand, implies that the integrity of someone or something is defended against any conceivable threat, but only if and when a threat becomes visible. The same thing applies to the person etc. defended, hence both object values are universally quantified (provided, of course, the form of the main verb permits it).", | |
