Plantinga pointed out that innumerable belief-desire pairs could account for a given behaviour; for example, that of a prehistoric hominid fleeing a tiger: Perhaps Paul very much likes the idea of being eaten, but when he sees a tiger, always runs off looking for a better prospect, because he thinks it unlikely the tiger he sees will eat him.
Plantinga ističe da bezbrojni vjerovanje-težnja parovi mogu biti uzrok za dano ponašanje npr. prehistorijskog hominida koji bježi od tigra: Možda Pavao jako voli ideju da bude pojeden od tigra, ali kada vidi tigra uvijek bježi da pronađe bolji izgled jer misli da je malo vjerojatno da će ga tigar pojesti.
