 Scotus thus had a clear way of expressing what Brentano later called intentionality, that is, the way the object of thought exists in the mind. It has objective existence in the mind on his view, which later came to be regarded as the mark of the mental (see Normore 1986; Pasnau 2003; King 2007; Cross 2014). Although the advantages of this approach over Aquinas’s are clear, problems remains concerning the ontological status of these mental contents. The medieval debate here is famous and features a wide variety of opinions (for a survey, see Tachau 1988). Scotus himself says that thought objects have a diminished kind of being, which is supposed to be a state between real being and no being at all. Although first accepting a similar view, Ockham would later subject this view to much criticism.
