Voluntarism Scotus was an Augustinian-Franciscan theologian. He is usually associated with
theological voluntarism, the tendency to emphasize God's will and human freedom in all philosophical issues. The main difference between
Aquinas's rational theology and that of Scotus is that Scotus believed 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. Scotus demonstrated his doctrine most forcefully in his
Ordinatio. Scotus gave the lecture,
Lectura I 39, during 1297–1299 to refute the view that everything is necessary and immutable. He claims that the aim of this lecture has two points (
Lectura I 39, §31): first, to consider the contingency in what is (
de contingentia in entibus); second, to consider how God's certain knowledge is compatible with the contingency of things. Scotus tries to defend the validity of Christian theology against the attack of ancient philosophers. The main argument is unpacked in
Lectura I 39, §§49–53. Scotus argues that a necessary being (God) is able to have contingent knowledge, and that although this knowledge is contingent, it is not necessarily mutable and temporal by that very fact. In
Lectura I 39 §1, Scotus asks, "whether God has determinate knowledge of things according to every aspect of their existence, as according to being in the future." He presents a counterview which claims that God cannot have determinate knowledge of the future. To support this counterview, he uses Aristotle's
De Interpretatione IX. In the following arguments, Scotus does not attempt to contradict Aristotle. He does not affirm or reject the ideas of Aristotle. The only issue he argues against is the proposition that God cannot have determinate knowledge of the future. Scotus appears to try to fully demonstrate that Aristotle's text is not contradictory to the Christian doctrine of God. Scotus argues that God wills with one single volition (
unica volitione) whatever he wills. God has one volition
ad intra, but this one volition can be related to many opposite things
ad extra. God can simultaneously will one thing at time 1 and the opposite thing at time 2. There are various possible interpretations of Aristotle's
De Interpretatione IX. For example, John Buridan (ca. 1300–1362) thought the Scotistic contingency theory was an
Aristotelian view. Buridan's judgment is all the more possible because of at least four reasons: (1) Aristotle's
De Interpretatione IX, 19a23-25 can be interpreted like the Scotistic contingency theory; (2) Scotus himself does not refute Aristotle's
De Interpretatione IX in
Lectura I 39 §§49–53; (3) Scotus, rather, tries to formulate his contingency theory with the help of other works of Aristotle in
Lectura I 39 §§51, 54; (4) Scotus introduces the diachronic feature of God's volition to his contingency theory as well as the synchronic feature.
Metaphysical argument for the existence of God Duns Scotus argued that it is better to construct a metaphysical argument for the existence of God, rather than the more common physical argument from motion favoured by Aquinas, following Aristotle. Though the version in
De Primo Principio is the most complete and final version, the
Ordinatio proof is usually offered. However, the
De Primo version gives a wider understanding of the argument as well as Scotus's metaphysical underpinnings for his argument for God's existence, but the
Ordinatio version will be followed here. Briefly, Scotus begins his proof by explaining that there are two angles we must take in arguing for the existence of an actually infinite being. First from the view of the Relative Properties of God and second from the Absolute Properties of God. Relative properties are those which are predicable of God in relation to creation; absolute properties are those which belong to God whether or not He chose to create. Under the first heading of Relative Properties, Scotus argues for a triple primacy of efficiency, finality and pre-eminence. From there he shows that one primacy implies the others, and finally there can only be one nature that is the First Efficient Cause, Ultimate End, and the Most Perfect Nature. From there the Subtle Doctor discusses the Absolute Properties of God. The First Being is intellectual and volitional, and the intellect and will are identical with the essence of this supreme nature. The First Being is also infinite being. While discussing the infinity of God, Scotus resurrects Anselm's argument and responds to the criticism that Anselm makes an illicit leap from concept to reality. Finally, he gives a definite answer of "yes" to the question of whether there exists an actually infinite being. The very next question of the
Ordinatio deals with the unicity of the nature thus proved to exist. However, the
De Primo Principio version concludes with this argument. The proof for the conclusion that "some efficient cause is simply first such that neither can it be an effect nor can it, by virtue of something other than itself, cause an effect"
Ordinatio I.2.43 runs like this: • Something can be produced. • It is produced either by itself, nothing, or another. • Not by nothing, for nothing causes nothing. • Not by itself, for an effect never causes itself. • Therefore, by another; call it
A. • If
A is first, then we have reached the conclusion. • If
A is not first, but also an effect, we return to 2).
A is produced either by itself, nothing, or another. • From 3) and 4), we say another,
B. The ascending series will either continue infinitely or we finally reach something which has nothing prior to it. • An infinite ascending series is impossible. • Therefore, etc. Scotus acknowledges two objections and deals with them accordingly. First is that he begs the question in assuming a first in the series. Here he argues that while many admit an infinite regress in an accidentally ordered series of causes, no philosopher admits infinite regress in an essentially ordered series. Scotus explains the differences between the two and offers proofs for the conclusion that an infinity of essentially ordered causes in a series is impossible. Second, it is objected that his proof is not really a demonstration since it begins with a contingent premise. That something is produced is contingent and not necessary. Therefore, the proof proceeds from a contingent and not a necessary premise. Scotus says that while that is true, it is utterly manifest that things are produced or effected. But in order to respond, Scotus makes a modal move and reworks the argument. Now he argues from the possibility of production. "It is possible that something can be produced" is a necessary proposition. From there he is able to conclude that it is possible that the first efficient cause exists, and if it is possible that it exists, then it does exist. He asserts that the last claim will be proved later in the argument. In the
Lectura proof, Scotus argues the following way: For more on this argument, see especially "Authors/Duns Scotus/Ordinatio/Ordinatio I/D2/Q2B".
Illuminationism Scotus argued against the version of
illuminationism that had been defended earlier in the century by
Henry of Ghent. 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".
Immaculate Conception Perhaps the most influential point of Duns Scotus's theology was his defense of the
Immaculate Conception of
Mary (i.e., that Mary herself was conceived without sin). At the time, there was a great deal of argument about the subject. The general opinion was that it was appropriately deferential to the
Mother of God, but it could not be seen how to resolve the problem that only with
Christ's death would the stain of
original sin be removed. The great philosophers and theologians of the West were divided on the subject (indeed, even
Thomas Aquinas sided with those who denied the doctrine). The
feast day had existed in the East (though in the East, the feast is just of the Conception of Mary) since the seventh century and had been introduced in several dioceses in the West as well, even though the philosophical basis was lacking. Citing
Anselm of Canterbury's principle, "
potuit, decuit, ergo fecit" (He [i.e., God] could do it, it was appropriate, therefore He did it), Duns Scotus devised the following argument: Mary was in need of redemption like all other human beings, but through the merits of Jesus'
crucifixion, given in advance, she was conceived without the stain of original sin. God could have brought it about (1) that she was never in original sin, (2) she was in sin only for an instant, (3) she was in sin for a period of time, being purged at the last instant. Whichever of these options was most excellent should probably be attributed to Mary. This apparently careful statement provoked a storm of opposition at Paris, and suggested the line 'fired France for Mary without spot' in the famous poem "Duns Scotus's Oxford," by
Gerard Manley Hopkins. Scotus's argument appears in
Pope Pius IX's 1854 declaration of the
dogma of the Immaculate Conception, "at the first moment of Her conception, Mary was preserved free from the stain of original sin, in view of the merits of Jesus Christ." Scotus's position was hailed as "a correct expression of the faith of the Apostles." During his pontificate,
Pope John XXIII recommended the reading of Duns Scotus's theology to modern theology students. == Veneration ==
