Conduct a Research to Justify God’s Existence

In some introductory philosophy textbooks and anthologies, the arguments for God’s existence are presented as ostensible proofs which are then shown to be fallible. For example, an argument from the apparent order and purposive nature of the cosmos will be criticized on the grounds that, at best, the argument would establish there is a purposive, designing intelligence at work in the cosmos. This falls far short of establishing that there is a God who is omnipotent, omniscient, benevolent, and so on. But two comments need to be made: First, that “meager” conclusion alone would be enough to disturb a scientific naturalist who wishes to rule out all such transcendent intelligence. Second, few philosophers today advance a single argument as a proof. Customarily, a design argument might be advanced alongside an argument from religious experience, and the other arguments to be considered below. True to Hempel’s advice (cited earlier) about comprehensive inquiry, it is increasingly common to see philosophies—scientific naturalism or theism—advanced with cumulative arguments, a whole range of considerations, and not with a supposed knock-down, single proof.

This section surveys some of the main theistic arguments.

5.2.1 Ontological arguments

There is a host of arguments under this title; version of the argument works, then it can be deployed using only the concept of God as maximally excellent and some modal principles of inference, that is, principles concerning possibility and necessity. The argument need not resist all empirical support, however, as shall be indicated. The focus of the argument is the thesis that, if there is a God, then God’s existence is necessary. In other words, God’s existence is not contingent—God is not the sort of being that just happens to exist or not exist. That necessary existence is built into the concept of God can be supported by appealing to the way God is conceived in Jewish, Christian, and Islamic traditions. This would involve some a posteriori, empirical research into the way God is thought of in these traditions. Alternatively, a defender of the ontological argument might hope to convince others that the concept of God is the concept of a being that exists necessarily by beginning with the idea of a maximally perfect being. If there were a maximally perfect being, what would it be like? It has been argued that among its array of great-making qualities (omniscience and omnipotence) would be necessary existence. Once fully articulated, it can be argued that a maximally perfect being which existed necessarily could be called “God”. For an interesting, recent treatment of the relationship between the concept of there being a necessarily existing being and there being a God, see Necessary Existence by Alexander Pruss and Joshua Rasmussen (2018: chapters one to three).

The ontological argument goes back to St. Anselm (1033/34–1109), but this section shall explore a current version relying heavily on the principle that if something is possibly necessarily the case, then it is necessarily the case (or, to put it redundantly, it is necessarily necessary). The principle can be illustrated in the case of propositions. That six is the smallest perfect number (that number which is equal to the sum of its divisors
