An analysis of ontological argument

This, he argued, proved the existence of an unsurpassably great necessary being. For example, the notion of a statement whose truth follows from logic and definitions will serve well enough for our purposes Papineau ; see also Russell Dover, [ Available onlineprepared by R.

Type-identity is the most obvious way to ensure the non-separateness of special and physical causes: For if it is possible that God exists, then there is some possible world in which God exists. Those interested in technical questions may also be interested in the topic taken up in Oppenheimer and Zalta and Gorbacz The former is the Necessary, which is pure existence.

The answer is that causal closure is needed to rule out interactionist dualism. The intuition underlying AxS5 is, as James Sennett puts it, that "all propositions bear their modal status necessarily.

In an analytic proposition, the predicate concept is contained in its subject concept; in a synthetic proposition, the predicate concept is not contained in its subject concept. So, for example, there are review discussions of ontological arguments in: Those who take themselves to have good independent reason to deny that there are any gods will take themselves to have good independent reason to deny that there are God-properties that form a non-trivial collection that is closed under entailment.

And, as it has already been explicated, perfection is prior to imperfection, actuality to potency, and existence to non-existence. Finally, he stated that it may be inconceivable for a non-existent being to create anything at all.

For that reason, Anselm dismissed any argument that did not relate to a being with necessary existence. For there is no imperfection in the reality of existence, and imperfection is added to existence only because of the quality of being caused, as it is impossible for an effect to be identical with its cause in terms of existence.

Perhaps somewhat surprisingly, Plantinga himself agrees: The creatures are distinct because each has a different set of essential properties. A is an essence of x if and only if for every property B, x has B necessarily if and only if A entails B Definition 3: He suggested that people cannot know the nature of God and, therefore, cannot conceive of God in the way Anselm proposed.

Detailed physiological research, especially into nerve cells, gave no indication of any physical effects that cannot be explained in terms of basic physical forces that also occur outside living bodies. Notice, however, that premise 1 of Gaunilo's argument is incoherent. Six follows from four and five.

There are many things to say about these objections: This distinguishes the claim that x exists from the claim that x necessarily exists and hence seems to imply that the latter, and only the latter, expresses a property.

Ontological Arguments

This is true as a matter of definition. However, "Anselm's point is that what exists and cannot not exist is greater than that which exists and can not exist. If a property is positive, then it is consistent, i. Unsourced material may be challenged and removed. Criticisms and objections[ edit ] Gaunilo[ edit ] One of the earliest recorded objections to Anselm's argument was raised by one of Anselm's contemporaries, Gaunilo of Marmoutiers.

Ontological argument

If such a being exists only in our mind, then a greater being—that which exists in the mind and in reality—can be conceived this argument is generally regarded as a reductio ad absurdum because the view of the fool is proven to be inconsistent.

But suppose that he went on to say, as if by a logical inference: These premises entail that God exists in no possible world, and hence that God does not exist in the actual world.

It is possible that a maximally great being exists. In effect, the function of a Carnap sentence is to provide a shorthand for talking about the putative state posited by the corresponding Ramsey sentence.

And then the reductio argument is produced to establish that that than which no greater can be conceived cannot exist only in the understanding but must also possess the property of existing in reality as well and all mention of the Fool, and what it is that the Fool believes, disappears.

The property of being God-like is positive Axiom 4: This is in contrast to material concepts, which can be verified by means of the senses.

Philosophy of Religion

Some commentators deny that St. If this is the case, then a being with maximal greatness exists in every world, and therefore in this world.

Ontological Arguments

He continued by arguing that there is no reason to view the creation of the world as "the most marvellous achievement imaginable". Given that that a minimally rational non-theist accepts that there is at least one possible world in which God does not exist, such a non-theist could offer the following counterargument: God is usually conceived of as an unlimited being.

Ontology: Ontology, the philosophical study of being in general, or of what applies neutrally to everything that is real. It was called “first philosophy” by Aristotle in Book IV of his Metaphysics. The Latin term ontologia (“science of being”) was felicitously invented by the German philosopher Jacob.

Ontological arguments are arguments, for the conclusion that God exists, from premises which are supposed to derive from some source other than observation of the world—e.g., from reason alone. The ontological argument is an argument for God’s existence based entirely on reason.

According to this argument, there is no need to go out looking for physical evidence of God’s existence; we can work out that he exists just by thinking about it.

This paper explores spiritual and aesthetic cultural values associated with ecosystems. We argue that these values are not best captured by instrumental or consequentialist thinking, and they are grounded in conceptions of nature that differ from the ecosystem services conceptual framework.

Recent discoveries in physics, cosmology, and biochemistry have captured the public imagination and made the Design Argument - the theory that God created the world according to a specific plan - the object of renewed scientific and philosophical interest.

The most prominent modern advocate of the ontological argument is Alvin izu-onsen-shoheiso.comnga is best-known for his defence of the view that religious belief is foundational, i.e.

that religious belief does not stand in need of external justification, but is also known for his work on modal logic, i.e. on the logic of possibility and necessity.
