 is "being qua being" (ens inquantum ens). Being in general (ens in communi), as a univocal notion, was for him the first object of the intellect. Metaphysics includes the study of the transcendentals, so called because they transcend the division of being into finite and infinite and the further division of finite being into the ten Aristotelian categories
Categories (Aristotle)
The Categories is a text from Aristotle's Organon that enumerates all the possible kinds of thing that can be the subject or the predicate of a proposition...

. Being itself is a transcendental, and so are the "attributes" of being — "one," "true," and "good" — which are coextensive with being, but which each add something to it.

The doctrine of the univocity of being implies the denial of any real distinction between essence
Essence
In philosophy, essence is the attribute or set of attributes that make an object or substance what it fundamentally is, and which it has by necessity, and without which it loses its identity. Essence is contrasted with accident: a property that the object or substance has contingently, without...

 and existence
Existence
In common usage, existence is the world we are aware of through our senses, and that persists independently without them. In academic philosophy the word has a more specialized meaning, being contrasted with essence, which specifies different forms of existence as well as different identity...

. Aquinas had argued that in all finite being (i.e. all except God), the essence of a thing is distinct from its existence. Scotus rejected the distinction. We can conceive of what it is to be something, without conceiving it as existing. Scotus denied this. We should not make any distinction between whether a thing exists (si est) and what it is (quid est), for we never know whether something exists, unless we have some concept of what we know to exist.

Categories

The study of the Aristotelian categories belongs to metaphysics insofar as the categories, or the things falling under them, are studied as beings. (If they are studied as concepts, they belong instead to the logician.) There are exactly ten categories, according to orthodox Aristotelianism. The first and most important is the category of substance
Substance theory
Substance theory, or substance attribute theory, is an ontological theory about objecthood, positing that a substance is distinct from its properties. A thing-in-itself is a property-bearer that must be distinguished from the properties it bears....

Accident (philosophy)
Accident, as used in philosophy, is an attribute which may or may not belong to a subject, without affecting its essence. The word "accident" has been employed throughout the history of philosophy with several distinct meanings....

, exist in substances. The nine categories of accidents are quantity, quality, relation, action, passion, place, time, position, and state (or habitus).

Individuation

Duns elaborates a distinct view on hylomorphism, with three important strong theses that differentiate him. He held: 1) that there exists matter
Matter
Matter is a general term for the substance of which all physical objects consist. Typically, matter includes atoms and other particles which have mass. A common way of defining matter is as anything that has mass and occupies volume...

 that has no form whatsoever, or prime matter, as the stuff underlying all change, against Aquinas (cf. his Quaestiones in Metaphysicam 7, q. 5; Lectura 2, d. 12, q. un.), 2) that not all created substances are composites of form and matter (cf. Lectura 2, d. 12, q. un., n. 55), that is, that purely spiritual substances do exist, and 3) that one and the same substance can have more than one substantial form — for instance, humans have at least two substantial forms, the soul and the form of the body (forma corporeitas) (cf. Ordinatio 4, d. 11, q. 3, n. 54). He argued for an original principle of individuation

 (natura communis), feature existing in any number of individuals. For Scotus, the axiom stating that only the individual exists is a dominating principle of the understanding of reality. For the apprehension of individuals, an intuitive cognition is required, which gives us the present existence or the non-existence of an individual, as opposed to abstract cognition. Thus the human soul, in its separated state from the body, will be capable of knowing the spiritual intuitively.

Formal distinction

Like other realist philosophers of the period (such as Aquinas and Henry of Ghent
Henry of Ghent
Henry of Ghent , scholastic philosopher, known as Doctor Solemnis , also known as Henricus de Gandavo and Henricus Gandavensis, was born in the district of Mude, near Ghent, and died at Tournai...

) Scotus recognised the need for an intermediate distinction that was not merely conceptual, but not fully real or mind-dependent either. Scotus argued for an formal distinction

 are formally distinct from the Divine essence. Similarly, the distinction between the 'thisness' or haecceity of a thing is intermediate between a real and a conceptual distinction. There is also a formal distinction between the divine attributes and the powers of the soul.

Voluntarism

Scotus was an Augustinian theologian. He is usually associated with voluntarism
Voluntarism
Voluntarism is a descriptive term for a school of thought that regards the will as superior to the intellect and to emotion. This description has been applied to various points of view, from different cultural eras, in the areas of metaphysics, psychology, sociology, and theology.The term...

, the tendency to emphasize God's will and human freedom in all philosophical issues. The main difference between Aquinas' rational theology and that of Scotus' is that Scotus believes certain predicates may be applied univocally — with exactly the same meaning — to God and creatures, whereas Aquinas insisted that this is impossible, and that only analogical predication can be employed, in which a word as applied to God has a meaning different from, although related to, the meaning of that same word as applied to creatures. Duns struggled throughout his works in demonstrating his univocity theory against Aquinas' analogy doctrine.

Existence of God

The existence of God can be proven only a posteriori, through its effects. The Causal Argument he gives for the existence of God
God
God is the English name given to a singular being in theistic and deistic religions who is either the sole deity in monotheism, or a single deity in polytheism....

 says that an infinity of things that are essentially ordered is impossible, as the totality of caused things that are essentially caused is itself caused, and so it is caused by some cause which is not a part of the totality, for then it would be the cause of itself; for the whole totality of dependent things is cause, and not on anything belonging to that totality. The argument is relevant for Scotus' conception of metaphysical inquiry into being by searching the ways into which beings relate to each other.

Illuminationism

Scotus argued against the version of illuminationism
Illuminationism
Illuminationism is a doctrine in theology according to which the process of human thought needs to be aided by God. It is the oldest and most influential alternative to naturalism in the theory of mind and epistemology...

 that had been defended earlier in the century by Henry of Ghent
Henry of Ghent
Henry of Ghent , scholastic philosopher, known as Doctor Solemnis , also known as Henricus de Gandavo and Henricus Gandavensis, was born in the district of Mude, near Ghent, and died at Tournai...

. In his Ordinatio (I.3.1.4) he argued against the sceptical consequences that Henry claimed would follow from abandoning divine illumination. Scotus argued that if our thinking were fallible in the way Henry had believed, such illumination could not, even in principle, ensure "certain and pure knowledge."
When one of those that come together is incompatible with certainty, then certainty cannot be achieved. For just as from one premise that is necessary and one that is contingent nothing follows but a contingent conclusion, so from something certain and something uncertain, coming together in some cognition, no cognition that is certain follows (Ordinatio I.3.1.4 n.221).

Immaculate Conception

Perhaps the most influential point of Duns Scotus' theology was his defense of the Immaculate Conception
