Peter Van Inwagen constructs a defense against the argument from evil in a series of 8 lectures. Van Inwagen provides a clear and discriminating formulation of the problem of evil by bringing out the distinctions between the multifarious angles of the problem. With sights set on answering the problem of evil for the sake of apologetics, he pursues both general and specific iterations of the argument. He provides a defense founded on free will that places an emphasis on love as being the good that justifies the prevalence of suffering. To complement this account, he delivers a justifying reason for animal suffering.
Van Inwagen formulates the problem in lecture 1. He outlines God’s properties in Lecture 2. In Lecture 3 he gives his standards for a failed philosophical argument. In lectures 4 and 5 he provides a defense for general evil. In lecture 6 he responds to the problem of individual evils. In lecture 7 he explores God’s reasons for beast suffering. Finally in lecture 8 he addresses God’s hiddenness.
Defenses and theodicies against the problem of evil are always made with reference to a specific formulation of the question. Evil for the purpose of this discussion is designated as all bad things, be it moral evil or the evil of natural catastrophe. Van Inwagen settles upon the task of answering the apologetic problem from evil, as opposed to personal consolation or doctrinal understanding. He seeks to answer the argument that given evil, God does not exist. Van Inwagen separates these notions into two separate arguments, the global argument which denies the existence of God on the basis of the incredible amount of suffering in the world, and the local argument which denies the existence of God on the basis of specific instances of suffering. Answering these arguments requires one to come up with a justifying reason, a good that can only be obtained alongside or by the risk of some evil. In his defense, Van Inwagen rejects the sufferer centered requirement, and in terms of scope seeks to cover both human and animal suffering.
The aim of Van Inwagen’s lectures is to show that the argument from evil fails the standard for philosophical failure. In lecture 3, he outlines his criteria for what would amount to a failed philosophical argument. His criteria for a philosophical argument to be a failure is that when presented in a debate setting with an excellently opposing interlocutor who aims to refute it, the argument fails to convince an ideal listener who is totally neutral on the subject. His goal is to show that the argument from evil cannot settle the question of God’s existence in the negative.
Van Inwagen’s conception of God follows Anselm in being the greatest possible being. His view, however, is not strictly within the bounds of classical theism. He has distinct notions of the concepts of omnipotence and immutability. Omnipotence according to Van Inwagen is the idea that God can do whatever does not imply a contradiction. For example, mountains have valleys between them, so it would be logically impossible to make two separate mountains that do not have a valley between them. Immutability is the idea that God cannot change, and Van Inwagen maintains that God’s attributes and intrinsic properties cannot change but He can relationally interact with us. Interaction implies change, but not the kind that threatens immutability.
The global argument from evil is that given the large amounts of persistent evils in the world, God must not exist since He would have either prevented or removed them. Van Inwagen gives two responses to this, first, he deployed the classic free will response, which posits that for the existence of free will God had to risk the presence of evil in the world. This is because the very nature of free will is that if God were to have control over it then it would cease to be free will. Van Inwagen operates under a libertarian conception of free will, which while acknowledging his disagreement with other thinkers, he believes is suitable above other views. Van Inwagen acknowledges two objections to the defense, the objection that free will does not defeat the actual suffering, and that free will being the reason for all evils fails in scope regarding natural disasters and things unrelated to human action. In response, he expands his defense with an emphasis on love as the primary good, and communication of our need for repentance as an explanation of natural evils.
In his expanded free will defense, Van Inwagen postulates a lengthy story that turns on two main themes, the fall of man, and the need for redemption. He postulates that the good for which free will was given to obtain is love. Mankind evolved over time to a point at which God miraculously raised them to rationality and gifted them with free will. In the misuse of free will, mankind has ruined itself and destroyed the initial goodness that God had intended. Thus, moral evil became rampant and life for humans was cursed with the burden of suffering evil both moral and natural. Because God is a merciful and loving God, He desires reconciliation with mankind. To that end, He does not intervene in the world to prevent all evils, both moral and natural, that may befall mankind (although he does shield us from many evils). He allows many evils so that mankind would know just how bad the world is without God, that they might realize their need of His help for redemption. Van Inwagen even proposes the idea that God takes the reins off physical processes, allowing them to become chaotic and random. God, the root of order and being, exposes us to what life is like without His ordering that we might understand how horrific a reality that is. As such, humans suffer the consequences of both the moral evil that they bring about, and the natural evils that befall them. In this way, God seeks to reconcile a love relationship with his creation and has a reason to allow natural disasters.
Van Inwagen recognizes however that while this may cover evils generally, it does not explain any particular horrific evil. He has not answered the local argument from evil by the free will defense. It may be granted that the justification for the presence of general evil in the world is successful, but why did God allow some particularly gruesome case of rape? To answer this, he argues for the idea that the number of evils that God can allow which will guarantee the effective communication of the message of necessary redemption is metaphysically vague. Because of this vagueness, the amount of suffering that God allows is slightly arbitrary. Van Inwagen explains this by showing that 99 sufferings would be basically just as bad as 100, this follows for each subsequent amount of suffering. God must draw a line somewhere. Additionally, in His allowances of sufferings, He cannot exempt everyone or His redemptive plan will be thwarted. Thus, even to prevent one more suffering would collapse the whole logic of the plan, as there is no good reason to spare one person over the other.
Finally, there is the objection of Rowe’s Fawn, henceforth called Bambi, who horrifically dies in a forest fire unrelated to human action and unwitnessed by humans. This cannot be a consequence of free will or instrumental to the instruction of mankind. Van Inwagen diffuses this argument by postulating that conscious creatures such as Bambi are required in the evolutionary chain to produce mankind, and that to always prevent their suffering counter to the occurrences of nature would be worse than allowing it because it would render irrelevant the ordered natural laws that God has set in place. Additionally, to spare one instance of Bambi would be arbitrary. Given these reasons, God allows the creature to suffer and perish.
With the problem of evil answered, atheists may raise an argument from God’s hiddenness. Since God wants us to know Him, why does He not directly reveal Himself? Van Inwagen gives two reasons, that it matters that we come to know Him in a certain way, and that our default way of knowing God has been disrupted by sin such that were He to reveal Himself directly we would begrudgingly accept Him rather than repentantly turn to Him.
