Book Review: “Existential Reasons for Belief in God” by Clifford Williams

Clifford Williams’ Existential Reasons for Belief in God (hereafter ERBG) is one of the most unique philosophy of religion books this reader has experienced. Rather than engaging in systematic arguments for the existence of God based upon sensory experience or philosophical reflection on the cosmos, Williams focuses on the subject of his subtitle: A Defense of Desires & Emotions for Faith.

Williams argues that “Christians need a conception of faith that is at least as much need-based as reason-based” (13). By uniting these into one concept Christians can help acquire and sustain faith (13). Need has been too often cast aside or ridiculed when it comes to faith (12).

After these introductory remarks, Williams jumps into detailed argument on the topic. Throughout the work he focuses on the concept that “people acquire their faith partly because they feel that it meets… existential needs and partly because they think that it makes sense or is true” (17, emphasis his). He begins his argument by surveying various types of needs people have (20ff). In chapter 3, Williams presents an existential argument for believing in God:

1. We need [various things like cosmic security, meaning, awe, delight in goodness, etc.]

2. Faith in God justifies these needs.

3. Therefore, we are justified in having faith in God. (32)

Clearly, this is not the typical argument for the existence of God. It’s not an argument for God’s existence at all. Williams recognizes this fact and argues that there is a distinction between evidential and existential reasons for belief. “In evidential justification for believing in God, one believes in God because of what one takes to be good evidence for doing so ” (41). By contrast, “The existential argument… says that faith in God is justified solely because it satisfies certain needs” (41). The argument, therefore, is not to show God exists, but to show that one can rationally believe in God.

Williams argues that such existential justification is permissible for a number of reasons. First, it helps clarify what nature is–it is not merely a faith based on aspects of reality but is instead a faith which is aimed at meeting certain needs (41). Second, people use existential reasoning in other instances–for example when they need to eat, they know that they are justified in going to meet that need (41).

Objections to this reasoning will, of course, be raised. The first objection is that “the existential argument does not guarantee truth” (61). With this objection, one sees the distinction between evidential and existential arguments becoming very clear. Williams returns to the food analogy. The existential argument there would be “1. Humans get hungry; 2. Eating food assuages hunger; 3. Therefore, eating food is justified” (63). Here the argument is not to establish the existence of food but rather to establish that eating food is justified (63). Similarly, with the existential argument for God, the argument is to establish the justification for believing in God (63-64). The argument presupposes, to some extent, the existence of God, and justifies that very belief (64).

Another interesting implication of the distinction between existential and evidential reasons for belief is that they can be combined to form a cumulative type of argument for the existence of God. Williams presents such an argument, which combines these types of reasoning:

1. We [have various existential needs.]

2. The best explanation for the presence of these needs in humans is that there is a God who has put them into humans.

3. Faith in God satisfies these needs.

4. Therefore, we are justified in believing there is a God in whom we can have faith. (67)

But, it may be objected, this argument justifies belief in any type of God! Consider someone who wants to believe in “Tyrant George” because they need humans to be tortured. They could be justified in believing in such a deity based upon their in-built needs. Williams frankly admits that this objection has its merit. The existential argument should be combined with reason (88). But he also takes issue with the “need” to torture. He delimits criteria which define “needs.” These criteria are:

1. Needs must be felt by many others… most people, if not all.

2. Needs must endure…

3. Needs must be significant…

4. Needs must be part of a constellation of connected needs, each of which meets the other criteria…

5. Needs must be felt strongly (89).

Why, however, should we believe these criteria? Williams argues that these criteria are independently verified and that they have been found useful in a number of settings, including psychology, courtrooms, and in assessment of unusual phenomena (90).

A third objection notes that not everyone feels existential needs. Williams challenges this notion and argues that most people will be aware of having the various needs he has outlined (119). Finally, it may be objected that we can satisfy these needs without faith. Williams counters by presenting a various tests wherein subjects may find temporary satisfaction in varied cases but their ultimate needs are not met (133ff).

Williams also surveys various thinkers–from Pascal to William James to Freud–and what they had to say about needs. He offers critiques of several theories while advancing his own.

There are those who may be thinking this is, so far, an entirely fideist account. Williams begs to differ and provides several reasons for why faith and emotion can work with the mind and reason to bring about a satisfactory, fulfilling faith (chapter 8). He concludes by showing various ways needs can draw us toward and away from God. Ultimately, “We humans find ourselves with certain deep and abiding needs… We need meaning… We need to kneel, so we kneel” (183).

One interesting thing to note throughout the book is that Williams continually underscores his points with excerpts written by people who have had various existential needs met by faith. These illustrations are also used to show various objections or difficulties people have when their needs aren’t met. They give ERBG a unique feel to it–one that is more intimate than most philosophy works. They’re also useful in that they give readers a concrete example for his argument.

Those coming from a very evidentialist view of apologetics and philosophy will have difficulties with this book, as this reader can attest to. It’s hard to admit that needs and emotions have their place in a rational world, but Williams does an excellent job focusing the reader on this fact. Too often, the focus is only upon a  posteriori arguments based upon the world as opposed to those based upon the human condition. Williams adequately defends existential reasons for belief, and–perhaps most importantly–presented them in a way to which evidentialists can relate and understand. He acknowledged difficulties in the argument and responded to many key objections. Hopefully, Williams has reopened an avenue for philosophers of religion to explore. Too long have they ignored the usefulness of existential reasoning.

  1. I get tired of hearing, “I don’t see the need for God/Jesus.” Maybe this book cane help with this issue.

  2. JJW,

    Thanks for the post. I really want to read the book… perhaps soon as soon as I get three other books out of the way. I do have a question. I just picked up Pascal’s Pensees recently. Does Williams build on it or disagree with Pascal and then suggest his own ideas?

    I also wonder about the thing that Eric mentioned. For quite sometime now, I have been antsy about doing things like telling others that they have holes/vacuums in their lives that only God can fill that hole or that they can only find rest in God, etc. Why? Because they tell you that life is quite good. They don’t need God. They are not looking to for an A or B in life. Getting a C is good enough because C stands for contentedness and that is what they claim to have, so “Why do we need Jesus? We are doing fine.”. I hope Williams will help me with this.

    I just read an interesting book by Michael Green, Sharing Your Faith With Family & Friends. Green mentions that the culture has gone through 3 phases: truth, relevancy and feelings. We have shifted from “Is it true?” to “Does it work?” to “Does it feel good?”. Green’s suggestion is that we not fail to address the issue of feelings in our evangelism… so for example, we tell people how we felt when we became Christians … or something like that.
