There exists a plethora of arguments about God and its existence. Even before the foundation of the earliest civilizations, man had been on a quest to shed light on the existence of God and its nature. Over many centuries, many different schools of thought tried to find an answer to the perennial question about God. Any thinker who strive to understand the different arguments about God should ask a basic question, “How likely is it that God exists?”
This preliminary question should always be the starting point of any debate about God. Our assumptions and presuppositions on this problem are very likely to enrich and color our assessment of our evidence for and against God’s existence. To establish the inherent probability of God’s existence as a priori is therefore a worthwhile meeting point for any argument we encounter on the subject. If our starting point is God’s non-existence, then it would be very challenging, and highly unlikely, to persuade us of God’s existence. Any positive points we will encounter about the existence of God would be viewed as fallacious and flawed if we start with the presumption of atheism that there’s no God. This would only make us ever more suspicious of any purported theistic proofs.
On the other hand, if we shall start with theistic presumption that God exists, it would be easier to find good points and persuasive arguments that others would normally not. Being open to intellectual discussions about God’s existence will make inconclusive evidence as confirmation of our suspicion deep inside us. This presumption will thus have a strong effect on our approach to counter any argument concerning God and its existence.
God’s Existence as Improbable
It is easy to think that God does not exist. If ever God exists, everything about him is unlimited–his whole being is infinite. Ockham’s approach on this subject would tell us to always prefer the simpler explanation. This means that if confronted with these two conflicting explanations, we must avoid postulating God’s existence to explain evidence. If presented with two explanations, one trying to give light to the argument about God’s existence and the other about non-existence, the second explanation is always the more likely explanation and therefore should be selected. For Ockham, the explanation not invoking God’s existence is the more economical one–it is economical to assume any number of finite beings than it is to postulate one infinite being. As a hypothesis, God’s existence is already considered highly unlikely to stand its ground. This condition makes the bias against theism justified.
Following this line of thought, it is even easy to think that God’s existence is not just improbable but even impossible. There are many conflicting doctrines about God and some have even shown self-contradictions themselves. If we take these conflicting explanations about God as a logical progression, it is very likely to arrive at a logical resolution. Logical contradictions are normally strong arguments against the thing being true or existent. This would establish a resolution that would trash theistic arguments about the existence of God.
God’s existence as Probable
For the purpose of argument, let us assume that many different contradictions about God can be resolved. If this is the case, then it is possible that God exists and would be a strong counter-argument against the improbability of God laid out above. In his work The Existence of God, Richard Swinburne observed that it is easier to postulate an unlimited force than a limited one. His argument says that if one postulates a limited force, one is actually postulating two things–the force and whatever that limits it. If, on the other hand, one postulates pure unlimited force, one is only postulating one thing–the force, without anything that limits it.
Scientists creating theories will normally use zeroes or infinites unless there’s a good reason not to. For example, the speed of light was conceived to be infinite until a strong experimental data confirmed a finite value. Scientists recognize that an infinite force has a higher probability than any great finite force. Using this argument, Swinburne believes that this methodology can be generalized. An infinite being is easier to conceive and the most probable being.
