What are the most
significant philosophical objections to religious belief in miracles, and how
best might one respond from the standpoint of Christian belief?
Traditionally,
Christian theism has held that belief in miracles is fundamental to its worldview. The apostle Paul writes, “And if Christ has
not been raised, your faith is futile...” (1 Cor. 15.17). However, since the enlightenment, religious
belief in miracles has been thoroughly tested.
Following on from the philosophical objections of the deists (Craig,
2008, 248), arguments against belief in miracles came thick and fast, the most
prominent of these being Hume’s argument in section X of his ‘Enquiries
concerning the human understanding’ (Hume, 1963). In this current essay the best of these
arguments and some of their modern day expansions will be discussed in order to
determine their significance. Following
on from this the various Christian responses to these arguments will be weighed
in order to find out which response is to be judged the best from the
standpoint of Christian belief. For this
essay a miracle will be defined as “a violation of a law of nature by a God”
(Swinburne, 1970, 11) unless otherwise stated.
There
are two main lines of argumentation when it comes to philosophical objections to
religious belief in miracles. One line focuses on the a priori impossibility of
miracles (cf. Craig, 2008, 248; Palmer, 2001, 184) and the other, made famous
by Hume, argues that miracles are so intrinsically improbable “That no
testimony is sufficient to establish a miracle, unless the testimony be of such
a kind, that its falsehood would be more miraculous...” (Hume, 1963, 116). The task, then, is to measure which objection
(or family of objections) is the most significant.
On inspection, the first argument
seems the weakest. Indeed, prominent
scholars like that of Mackie (1992, 23) and Palmer (2001, 184), Hume and Flew (Palmer,
2001, 186) all reject the idea that miracles can be ruled out a priori. This a priori argument rests on the
assumption that the natural law is a closed system, or as Palmer (2001, 184) writes,
echoing Mckinnon, “laws of nature state what happens, anything that happens
must conform to those laws.” Naturally,
if this was the case, the concept of ‘miracle’ would be logically impossible as
the laws of nature could not be violated, by definition miracles could not
occur. However, as has been rightly pointed out by Swinburne (1970, 26) natural
laws, “describe what happens in a regular and predictable way.” Our
understanding of natural law is reached by inductive reasoning and is thus
based on probabilities, not necessities and therefore miracles cannot be ruled
out a priori.
The second argument however, is much
more challenging and not as easy to resolve. It is necessary to look at this in
more detail to understand it more fully. Hume’s argument from the improbability of
miracles is based on two separate forms of evidence (Earman, 2000, 20), those
being experience and testimony. According
to Hume there is a conflict between the two in the case of a miracle. We have a), the testimony given by a person
for the miracle and b), uniform experience which he says counts against the
occurrence of miracle. Hume argues that
uniform experience always outweighs testimonial evidence for miracles, and that
testimonial evidence is more likely explained in naturalistic terms (Hume,
1963, 113-114) so that a miracle can never be verified.
Antony
Flew went on to enhance Hume’s argument by focussing on historical studies with
reference to miracle claims. Flew
writes, “...whether or not anything did happen in the past inconsistent with
what we at present believe to be a law of nature, one cannot possibly know on
historical evidence that it did so happen.” (Palmer, 2001, 217). Flew says that by its very nature historical
enquiry cannot tell us whether a miracle has occurred. Historical evidence, then, according to Flew
is subordinate to the “evidence still available to us” (Palmer, 2001, 186) and
according to this evidence, which is “directly verifiable”, miracles are
“physically impossible” (Palmer, 2001, 186). Flew’s argument, and Hume’s
argument, poses a significant problem for religious belief in miracles.
Following
on from his main argument in ‘Of Miracles’ Hume puts forward another four
arguments in order to back up his claim that testimonial evidence is unreliable
in assessing the miraculous (Palmer, 2001, 180). His final argument of these four is of
particular interest. Hume (1963,
121-122) writes that 1) the aim of any miracle “is to establish the particular
system to which it is attributed...”, 2) that this happens in all religions (or
at least a good deal of them), and 3) therefore the miracle claims of each
religion cancel each other out. This
argument seems quite strong prima facie
and will be returned to later.
It
is recognized, then, that Hume puts forward some fairly well reasoned arguments,
and, stemming from this, modern scholars like Flew have strengthened this
argument with particular reference to historical study. Of course Hume’s arguments and those of the
deists did not go unquestioned by the Christian community of the period. Indeed, there were a plethora of responses
from the religious and philosophical community in defence of religious belief
in miracles by the likes of Jean Le Clerc, Jacob Vernet, Thomas Sherlock and
William Paley to name only a few (Craig, 2008, 252-256). Despite this, it was the philosophical
objections to religious belief in miracles “that posterity gave an eye to...”
(Craig, 2008, 259).
It
seems that there are at least two main ways in which Christians might respond
to these arguments. The first way in
which the Christian could respond is by accepting the arguments against
religious belief in miracles. For example,
theologians like Bultmann (Bultmann, 1953, 5) and Tillich (Palmer, 2001, 199) redefine
the concept of miracle as ‘myth’ or as ‘symbolism’, thus dismissing the
traditional understanding. However,
whether this is the best response for the Christian is to be questioned.
This
approach is not likely to appeal to the regular Christian in the pew, nor is it
in line with traditional and orthodox Christian thought as was briefly pointed
out in the introduction (cf. Geivett, 2010, 595). Moreover some scholars imply that this
approach isn’t actually Christian at all, in that it leads to “Christless and
even atheistic Christianity” (Craig, 2008, 248). Thus those Christians who are
not inclined to the bultmanian or tillichian approach will be glad to hear that
it is not the only available Christian response to objections against belief in
miracles, and nor is it a necessary one. A second and more palatable approach can be
taken which retains the traditional and more orthodox stance. The Christian and non-Christian alike (Cf.
Earmann, 2000) have employed strong counter arguments in response to Hume and
Flew, some so confidently and damningly so that it is alleged that Hume’s
argument from the intrinsic improbability of miracle is an “abject failure”
(Earmann, 2000, 3).
One
of the lines of argument that can be taken in response to Hume is appealing to
the probability calculus. Since Hume
wrote ‘Of Miracles’ numerous developments in probability theory have taken
place, revealing hole’s in Hume’s reasoning (Craig, 2008, 270). He is mistaken on a number of points. Firstly,
Hume focuses almost solely on the intrinsic improbability of the miraculous,
ignoring the wider factors that need to be taken into account when calculating
probability (Craig, 2008, 272). This is a mistake. In calculating the probability of a miracle
‘M’ we not only need to take into account its intrinsic probability given our
background knowledge ‘B’ (The nature of ‘B’ will be expanded on later), but
also its explanatory power ‘E’. The
calculation is as follows (cf. Craig, 2008, 271),
Pr(M|E&B)
Pr(M|B) Pr(E|M&B)
= x
Pr(not-M|E&B) Pr(not-M|B) Pr(E|not-M&B)
On the
right hand side of the equation we have two ratios. Firstly, that of the intrinsic probability of
‘M’ (Pr(M|B)) and secondly, to the right, the explanatory power of ‘M’ (Pr (E|M&B)), the denominators being
the probability of their negations. If
the explanatory power of ‘M’ is sufficiently high to be equal to or greater
than the intrinsic improbability of the miracle, then ‘M’ may be more probable
than not (Craig, 2008, 272). What is
shown by the probability calculus is that Hume’s argument is flawed in that he
leaves out significant factors contributing to calculating the probability of
‘M’. He gets close to understanding
this, but ultimately fails to expand on or develop this sufficiently (Craig
2008, 272).
Secondly, Hume incorrectly goes
about calculating the intrinsic probability of ‘M’ by using the frequency model
of probability. Craig (2008, 274) paraphrases Earman in pointing this out,
“...the frequency model of probability simply will not work in this
context.” If one were to take this
theory of probability on board it would undermine a good deal of scientific
study as well (Craig, 2008, 274).
Therefore this mistake, in conjunction with the others, shows that Hume
largely fails in his argument against religious belief in miracles.
But what of Hume’s other argument,
that the miracles of different religions cancel each other out? Mackie seems to think that this argument can
be dealt with or at least avoided by taking the stance of theological
liberalism or pluralism (Mackie, 1992, 15).
Again, this is a viable option, but not preferable to those who are not
in favour of a more liberal explanation.
Another way of responding is to point out, along with Craig (2008, 277)
that the question is ‘empirical’ and demands investigation as to whether the
evidence supports a Christian claim (the resurrection for example) as opposed
to a non-Christian miracle claim. Earman (2000, 70) agrees in that Hume had to
“...leave the high ground and descend into the trenches where...there were
opponents...[who] were prepared to argue for...the superiority of the New
Testament miracle stories over heathen miracle stories.”
What
can be said of Antony Flew’s argument against religious belief in miracles on
historical evidence? As it happens, this
argument, like those of Hume has also been challenged. Flew’s argument rests on the proposition that
historical evidence is subordinate to scientific evidence on the grounds that
“scientific propositions, unlike statements about the past, can be repeatedly
verified.” (Palmer, 2001, 192, cf. Swinburne, 1970, 42). But as Swinburne (1970, 42) points out, “We
can go on and on testing for the truth of historical as of scientific
propositions”. Both historical and scientific propositions are “established
ultimately in a similar kind of way” (Swinburne, 1970, 43). Thus, Swinburne
asks why, now, should we assume that scientific propositions take precedence
over historical propositions? “To make
the supposition that they are to be treated differently is to introduce a
complicating ad hoc procedure for
assessing evidence.” (Swinburne, 1970, 43).
Therefore the argument put forward by Flew also fails.
One can say therefore, that there
could be enough evidence of particular kinds, to “outweigh the evidence of
physical impossibility.”(Swinburne, 1970, 51).
Nevertheless, “There is, even on theistic assumptions, a strong
presumption in favour of a natural explanation for any physical event.”
(Geivett, 2010, 601) Indeed those in
favour of claiming that a miracle has occurred bear the burden of proof
(Palmer, 2001, 195). But in
acknowledging this, one more factor should be noted in calculating the
probability of the miraculous. The
crucial component in considering the probability of ‘M’ will be the intrinsic
probability of ‘M’ given background knowledge ‘B’. Thus the intrinsic probability of ‘M’ is
relative to ‘B’. If one assumes already
that God doesn’t exist then the intrinsic probability of ‘M’ occurring will be
very low. However, if one assumes
theism, “...and that this theism grounds a reasonable expectation that God would
act on behalf of humanity-” (Geivett, 2010, 604, cf. Swinburne, 1970, 65, cf.
Lewis, 1947, 4), then the intrinsic probability of ‘M’ will increase
significantly. “For if there exists a
being able to produce V [violations of laws of nature] (as a god would be), it
is natural to attribute them, if otherwise inexplicable, to his agency.”
(Swinburne, 1970, 65). Thus, a
cumulative case could be made for Christian theism on this basis. The Christian
could build up a case, by arguing for God’s existence and then going on to
apply this in an argument for the occurrence of a miracle, say, the
resurrection. Therefore, not only can
the Christian respond that miracles are indeed, verifiable, but they can
include arguments from miracles in conjunction with arguments from natural
theology to compose a cumulative apologetic (cf. Swinburne, 1970, 69).
It
has been seen that numerous philosophical arguments have been made against
religious belief in miracles. It was
noted that the ongoing philosophical dialogue concerning miracles originated in
the enlightenment period and that Christian and none Christian alike
endeavoured to understand miracle claims within the prevailing zeitgeist. From this background, Hume’s most significant
argument arose and was built on by many, the most prominent being Antony Flew. It was shown that the Christian could respond
in two main ways. The first being to
dismiss supernatural miracle claims, the second being to employ philosophical
counter arguments to the objections of Flew and Hume in order to preserve the
rationality of religious belief in the miraculous. The second was deemed the best in that it
retained the possibility of affirming traditional, orthodox Christian
belief. These counter arguments have
been shown to be successful, and can be used positively by the Christian in an
accumulative apologetic for his or her worldview as the probability of such
claims largely depends on background information. Therefore, there is good reason to think that
this second approach is the best and most successful way for the Christian to
respond to philosophical objections to religious belief in miracles.
