Conceptual analysis of what it is to be a cause of the universe enables us to recover a number of striking properties which this ultramundane cause must possess and which are of theological significance. For example, the cause must be uncaused, since, as we have seen, an infinite regress of causes is impossible. One could, of course, arbitrarily posit a plurality of causes in some sense prior to the origin of the universe, but ultimately, if the philosophical kalam arguments are sound, this causal chain must terminate in a cause which is absolutely first and uncaused. There being no reason to perpetuate the series of events beyond the origin of the universe, Ockham’s Razor, which enjoins us not to posit causes beyond necessity, strikes such further causes in favor of an immediate First Cause of the origin of the universe. The same principle dictates that we are warranted in ignoring the possibility of a plurality of uncaused causes in favor of assuming the unicity of the First Cause.
This First Cause must also be beginningless, since by contraposition of premiss (1.0) whatever is uncaused does not begin to exist. Moreover, this cause must be changeless, since, once more, an infinite temporal regress of changes cannot exist. We should not be warranted, however, in inferring the immutability of the First Cause, since immutability is a modal property, and from the Cause’s changelessness we cannot infer that it is incapable of change. But we can know that the First Cause is changeless, at least insofar as it exists sans the universe. From the changelessness of the First Cause, its immateriality follows. For whatever is material involves incessant change on at least the molecular and atomic levels, but the uncaused First Cause exists in a state of absolute changelessness. Given some relational theory of time, the Uncaused Cause must therefore also be timeless, at least sans the universe, since in the utter absence of events time would not exist. It is true that some philosophers have argued persuasively that time could continue to exist even if all events were to cease (Shoemaker, 1969; Forbes, 1993), but such arguments are inapplicable in the case at hand, where we are envisioning, not the cessation of events, but the utter absence of any events whatsoever. In any case, the timelessness of the First Cause sans the universe can be more directly inferred from the finitude of the past. Given that time had a beginning, the cause of the beginning of time must be timeless. [20] It follows that this Cause must also be spaceless, since it is both immaterial and timeless and no spatial entity can be both immaterial and timeless. If an entity is immaterial, it could exist in space only in virtue of being related to material things in space; but then it could not be timeless, since it undergoes extrinsic change in its relations to material things. Hence, the uncaused First Cause must transcend both time and space and be the cause of their origination. Such a being must be, moreover, enormously powerful, since it brought the entirety of physical reality, including all matter and energy and space-time itself, into being without any material cause.
Finally, and most remarkably, such a transcendent cause is plausibly taken to be personal. Three reasons can be given for this conclusion. First, as Richard Swinburne (1991, pp. 32-48) points out, there are two types of causal explanation: scientific explanations in terms of laws and initial conditions and personal explanations in terms of agents and their volitions. For example, in answer to the question, “Why is the kettle boiling?” we might be told, “The heat of the flame is being conducted via the copper bottom of the kettle to the water, increasing the kinetic energy of the water molecules, such that they vibrate so violently that they break the surface tension of the water and are thrown off in the form of steam.” Or alternatively, we might be told, “I put it on to make a cup of tea. Would you like some?” The first provides a scientific explanation, the second a personal explanation. Each is a perfectly legitimate form of explanation; indeed, in certain contexts it would be wholly inappropriate to give one rather than the other. Now a first state of the universe cannot have a scientific explanation, since there is nothing before it, and therefore it cannot be accounted for in terms of laws operating on initial conditions. It can only be accounted for in terms of an agent and his volitions, a personal explanation.
Second, the personhood of the First Cause is already powerfully suggested by the properties which have been deduced by means of our conceptual analysis. For there appear to be only two candidates which can be described as immaterial, beginningless, uncaused, timeless, and spaceless beings: either abstract objects or an unembodied mind. Abstract objects like numbers, sets, propositions, and properties are very typically construed by philosophers who include such things in their ontology as being precisely the sort of entities which exist necessarily, timelessly, and spacelessly. Similarly philosophers who hold to the possibility of disembodied mind would describe such mental substances as immaterial and spaceless, and there seems no reason to think that a Cosmic Mind might not also be beginningless and uncaused. No other candidates which could be suitably described as immaterial, beginningless, uncaused, timeless, and spaceless beings come to mind. Nor has anyone else, to our knowledge, suggested any other such candidates. But no sort of abstract object can be the cause of the origin of the universe, for abstract objects are not involved in causal relations. Even if they were,since they are not agents, they cannot volitionally exercise a causal power to do anything. If they were causes, they would be so, not as agents, but as mindless events or states. But they cannot be event-causes, since they do not exist in time and space. Even if we allow that some abstract objects exist in time (for example, propositions which change their truth-value in virtue of the tense of the sentences which express them), still, in view of their abstract nature, it remains utterly mysterious how they could be causally related to concrete objects so as to bring about events, including the origin of the universe. Nor can they be state-causes of states involving concrete objects, for the same reason, not to mention the fact that in the case at hand we are not talking about state-state causation (that is, the causal dependence of one state on another), but what would amount to state-event causation (namely, the universe’s coming into being because of the state of some abstract object(s)), which seems impossible. Thus, the cause of the universe must be an unembodied mind.
Third, this same conclusion is also implied by the fact that only personal, free agency can account for the origin of a first temporal effect from a changeless cause. We have concluded that the beginning of the universe was the effect of a First Cause. By the nature of the case that cause cannot have any beginning of its existence nor any prior cause. Nor can there have been any changes in this cause, either in its nature or operations, prior to the beginning of the universe. It just exists changelessly without beginning, and a finite time ago it brought the universe into existence. Now this is exceedingly odd. The cause is in some sense eternal and yet the effect which it produced is not eternal but began to exist a finite time ago. How can this be? If the necessary and sufficient conditions for the production of the effect are eternal, then why is not the effect eternal? How can all the causal conditions sufficient for the production of the effect be changelessly existent and yet the effect not also be existent along with the cause? How can the cause exist without the effect
