Abstract

Ockham defines intuition as the kind of cognition on the basis of which it is not only possible to evidently judge that a thing exists when it exists, but also that a thing does not exist when it does not exist. He makes a further distinction between natural intuition and supernatural intuition. The aim of this paper is to determine what, according to Ockham, can be judged evidently by means of natural intuition and what can only be judged evidently by means of supernatural intuition. It is commonly assumed that by natural intuition we can make only affirmative judgements, whereas by supernatural intuition we can make both affirmative and negative judgements. The paper shows that this way of contrasting the two is mistaken. The paper argues instead that also natural intuition, according to Ockham, enables us to make both affirmative and negative judgements.
