The original title for this discourse was to be Faith Seeking Understanding.[1]
Ontological arguments
The Proslogion marked what would be the beginning of
Saint Anselm's famous and highly controversial
ontological arguments for the
existence of God. Anselm's first and most famous argument is found at the end of Chapter II, and it is followed by his second argument. While opinions concerning Anselm's twin ontological arguments widely differ—and have differed since the Proslogion was first conceived—there is a general consensus that the argument is most convincing to Anselm's intended audience:
Christian believers who seek a
rational basis for their
belief in God.
First argument
There are various reconstructions of Anselm's first argument. Scott H. Moore's analysis is as follows:[2]
Proposition 1: God is a being than which none greater can be conceived.
Proposition 2: If existence in reality is greater than existence in the mind alone, an imagined being who exists only in our mind is not a "being than which none greater can be conceived." A being than which none greater can be conceived must also exist in reality, where failure to do so would be a failure to be such.
Conclusion: Thus a being than which none greater can be conceived must exist, and we call this being God.
Because it is greater to exist in reality than in the mind only, the being that nothing greater than can be thought of will exist both in the mind and in reality.
Kant's objection
The German philosopher
Immanuel Kant gave an objection to the argument, although it would be toward ontological arguments in general, rather than at Anselm's specifically. In fact, it is actually unclear as to whether Kant had Anselm in mind at all. Kant's objection famously states that "existence is not a predicate". If Kant were considering Anselm's work in his analysis, he certainly left it up to the reader to grasp the applicability of the objection. One possible interpretation is to say that, because existence is not a predicate, a being that exists could not be said to be greater than one that does not exist; they would be equal.[citation needed]
Second argument
Donald Viney renders Anselm's second argument as follows:[3]
"God" means "that than which nothing greater can be conceived."
The idea of God is not contradictory.
That which can be thought of as not existing (a contingent being) is not as great as that which cannot be thought of as not existing (a necessary being).
Therefore, to think of God as possibly not existing (as contingent) is not to think of the greatest conceivable being. It is a contradiction to think of the greatest conceivable being as nonexistent.
Therefore, God exists.
Formal Reconstruction in a set theoretic form (by Gyorgy Gereby)[4]
Vocabulary for the argument in a set logical form
R – not empty set of mind-independent real things
S – not empty set of (individual) people
P – set of sentences or propositions
I – set of mental contents (represent the meaning of sentences of P)
T = S XP --> I – is the function of “thinking of”, which assigns to sentences uttered by persons an intelligible element i of I
C = I --> R correspondence-function, which assigns to certain elements of I certain elements of R
V = { i | i ∈ I, ∃ r. r ∈ R, r = C (i)} – Set of mental things that have a counterpart in R
U = I \ V – set oft hings that do not have a counterpart in R
b ∈ S – individual name of the fool
g – individual name for god
The Argument of Anselm
T (b, ‘

The Fool says in his heart that there is no
God.
Existential

g = def !x. ~ ∃ y. y ≥ x
God is the only one thing greater than

What is said and understood is in the mind.
Assumption,

g ∈ I
What is understood by the Fool of the
definition is in his intellect.
∀ i. ∀i*. i* ∈ U, i ∈ V, i > i*
Whatever is in the intellect and also in
reality is greater than that which is solely
in the intellect.

g ∉ V
g is only in the intellect. (‘God is only a concept’ – however, there is a god-concept)

V ≠ Ø
V is not empty.
Assumption
∃ g*. g* ∈ V > g ∈ U
The God which is an element of V is a
greater thing than God in the mind.

God is the greater-than-which-can-not-be-conceived and God is not the greater-than-which-can-not-be-conceived.

Supplement
Anselm writes in Chapter XI that "you [God] are not only that than which a greater cannot be conceived, but you are a being greater than can be conceived."

Translations
There are different translations of the Proslogion.
Up now, slight man! flee, for a little while, your occupations; hide yourself, for a time, from your disturbing thoughts. Cast aside, now, your burdensome cares, and put away your toilsome business. Yield room for some little time to God; and rest for a little time in him. Enter the inner chamber of your mind; shut out all thoughts save that of God, and such as can aid you in seeking him; close your door and seek him. Speak now, my whole heart! speak now to God, saying, I seek your face; your face, Lord, will I seek (Psalms xxvii. 8).[7] And come you now, O Lord my God, teach my heart where and how it may seek you, where and how it may find you.
Modern translation
Come on now little man, get away from your worldly occupations for a while, escape from your tumultuous thoughts. Lay aside your burdensome cares and put off your laborious exertions. Give yourself over to God for a little while, and rest for a while in Him. Enter into the cell of your mind, shut out everything except God and whatever helps you to seek Him once the door is shut. Speak now, my heart, and say to God, "I seek your face; your face, Lord, I seek.
