On The Leibnizian Cosmological Argument

By R.N. Carmona

A Christian on the Humans of New York Instagram page brought up the Leibnizian Cosmological Argument (LCA) and named a few of its Christian defenders. Like I’m fond of pointing out, in naming just Christian defenders of the argument, it is likely he hasn’t considered actual objections. He’s read a degraded form of objections via the lens of these Christian authors. This is why I call apologetics, pseudo-philosophy.

In actual philosophical discourse, the participants in a given discussion are as charitable to one another as possible and they try very hard to ensure that nothing is lost in translation. They constantly correct themselves if they misinterpret what their opponent has said or they attempt to show that their interpretation better captures what their opponent is trying to say. Apologists don’t do this. Apologists straw man an objection, sometimes in ways that seem sophisticated, in order to make the argument or counter-argument easier to address. This is precisely why I advised him to deal with J.L. Mackie, for example–to read him directly and not through the lens of one of his favored authors. Then he would find that even Christians reject the Leibnizian Cosmological Argument (LCA).

A quick example of what I mean: in responding to my Argument From Cosmology, my opponent says that the opposite of my conclusion is as follows: the fact that an x can’t be shown to exist in relation to y doesn’t mean that x doesn’t exist*; in other words, that god can’t be shown to exist in relation to the Earth doesn’t mean god doesn’t exist. Yet on Judaism and Christianity, god created the Earth. Modern science tells us that planets have no creator; they form naturally over an extended period of time. We have real time data of planet formation in other systems. The history of our planet doesn’t resemble anything mentioned in the Bible. By extension, I argue that god doesn’t exist in relation to the universe, since he didn’t create it. Modern cosmology tells us as much.

His assertion is not enough to refute my argument. In fact, all he’s concluding is the opposite of what he misunderstood as my conclusion. My actual conclusion is this: x does not exist in relation to y iff it is necessary that x exist in relation to y. If god did not create the Earth or the universe, he doesn’t exist in relation to either, and by extension, doesn’t exist; however, on Christianity, it is necessary that he does. This is precisely what his favored LCA says. Through the Principle of Sufficient Reason (PSR), for every being or state of affairs that exist, there is a sufficient reason for why they exist. It then adds, that for every being or state of affairs that exist, there is a necessary reason for why they exist. Therefore, god is the necessary and sufficient reason for why these states of affairs exist.

My Argument From Cosmology best captures a decisive criticism of the LCA without directly engaging it. J.L. Mackie stated that PSR need not be assumed by reason. Reason only asks for antecedent causes and conditions that explain each being or state of affairs. These are considered facts until they themselves are explained by something prior to them. On reason, nothing is prerequisite beyond this.

Thus, going back to my conclusion, x does not exist in relation to y iff it is necessary that x exist in relation to y. In order for Christianity to hold true, god would have had to create the Earth and the universe. If we have reason to doubt that he created the Earth, and modern science establishes this conclusively, then we have much reason to doubt that he created the universe. If the Earth can be explained by antecedent causes and conditions, then the universe can as well. My argument offers a number of plausible explanations fielded in modern cosmology all whilst arguing that there cannot be the type of causation Christians would require, i.e., the type of causation that allows for an immaterial agent to create material objects. At best, such causation is unknowable and it is probable that there will be no hard evidence for it; hence the Christian must retreat to agnosticism. At worst, such causation is impossible and there cannot be any evidence for it; thus, the Christian must retreat to atheism.

Ultimately, my argument addresses the LCA by implication, i.e., my argument implies a defeater of the LCA. Therefore, I do not have to address it directly. The same can be said of the KCA. Rebuttals to both arguments are implicit in my argument. That fact alone should give apologists pause.

In any case, my point has been made: apologetics is pseudo-philosophy. Apologists prop it up by being uncharitable and purposely (in most cases) misinterpreting a claim or argument made by atheists. Apologists are also modern sophists: it matters not how things might be or probably are; what matters is what they think is the case, what they say is the case, or what they deem possible–as though possibility implies probability. Apologists are also quite fond of straw men, which they use to make their arguments seem superior to those of their opponents. Unlike them, I have defined PSR correctly and I’ve summarized the LCA charitably. However, I’ve also shown that my Argument From Cosmology considers the LCA, albeit indirectly. My argument implies a decisive blow to the LCA. It is therefore necessary to deal with my argument directly; it isn’t enough to choose a favored argument and deem it superior on the basis of a misinterpretation of my conclusion.

*His assessment is correct assuming that x isn’t necessary with relation to y. The fact that I (x) cannot be explained with relation to an invention (y) doesn’t mean I do not exist. Even the actual inventor of invention (y) doesn’t have this sort of connection to the invention in question. Another agent could have been the inventor. On Christianity, however, there are no other gods and hence no other creators. Thus, if god did not create the Earth, there is reason to doubt he created anything else in the universe and therefore, the universe itself. As stated, for Christianity to be true, it need only be shown that god is necessary in this possible world; the LCA, as originally formulated, wants Anselm’s deity and therefore, on the LCA, god is necessary in all possible worlds. My argument casts much doubt on this, especially since god is the necessary being antecedent to all contingent beings. If this connection fails on a minor front, e.g., god didn’t create all baseballs, that’s fine, for even then he would underlie the reason for the reason of the baseballs, namely human beings. If it fails on a major front, as I’ve shown in the case of the Earth and all planets for that matter, a glaring problem arises for Christians, for even if they posit a being that willed the laws of physics, what they have is a deity far removed from the deity in the Bible. That would make for a separate discussion altogether.
