Introduction to Philosophy
David Hume, "Design Argument: Critique"
Abstract: David Hume's version of the design
argument from Dialogues Concerning Natural Religion
is presented and his objections to that argument are summarized.
Hume's analysis shows the disanalogy between
the features of the universe and features of the purported Deity.
- Explain the meaning of the phrase, "as the
cause ought only be proportioned to the effect…" Aren't
the effects of causes often surprising? How do you think
the notion of cause is related to scientific law?
- List the analogical respects, pointed out
by Philo, between the characteristics of the world and the
inferred characteristics of the Deity.
- David Hume (1711-1776) formulated a clear and succinct version of the
design argument.
-
- Hume cites the following objections to the design argument
quoted below in 2a.
- It
- Generally speaking, Hume's criticism is devastating for the
design argument concluding in an anthropomorphic conception of
God
- The main general objection given by Hume is as follows:
“But as all perfection is entirely
relative, we ought never to imagine, that we comprehend the
attributes of this divine Being, or to suppose, that his
perfections have any analogy or likeness to the perfections
of a human creature.” Dialogues concerning Natural
Religion (1779) in Dialogues and Natural History of
Religion, ed. by J.A.C. Gaskin (Oxford: Oxford
University Press, 1993), 44.

- Notes
are arranged in response to the
questions stated above in reference to chapter
"Critique
of the Design Argument" from Dialogues Concerning
Natural Religion by David Hume in Reading for Philosophical
Inquiry.
- Explain the meaning of the phrase, "as the
cause ought only be proportioned to the effect…" Aren't
the effects of causes often surprising? How do you think the
notion of cause is related to scientific law?
- Hume assumes that similar effects result from similar causes.
- This assumption follows from straight-forward inductive reasoning:
If we seen many events of kind E₁ followed by events of the
kind E₂, then we conclude with some probability that
events of kind E₁ cause or are constantly conjoined with
events of the kind E₂.
- Events of kinds E₁ and E₂ are assumed to be ontologically
similar—i.e., they are subject to normal conditions
of experience.
- If Hume's notion of proportionality of cause and effect
were correct, laws involving different levels of phenomena
would not have meaning. I.e., consider the ideal
gas law.
- PV = nRT
- The ideal gas law states the Pressure of a gas
multiplied times the Volume it occupies is equal to
the number of moles of gas times the universal
gas constant R and the Temperature Kelvin.
- An ideal gas is not “proportioned” to actual
temperature, pressure, or volume.
- In general, causality is viewed by Hume as uniform constant conjunction
or regularity of succession of events, and a scientific law is a
statement of that regularity.
- List the analogical respects, pointed out by
Philo, between the characteristics of the world and the
inferred characteristics of the Deity.
- First, David Hume's interlocutor Cleanthes presents a clear and succinct
formulation of the design
argument:
- “Look round the world: contemplate the whole and every part of
it: You will find it to be nothing but one great machine,
subdivided into an infinite number of lesser machines, which
again admit of subdivisions to a degree beyond what human
senses and faculties can trace and explain. All these various
machines, and even their most minute parts, are adjusted to
each other with an accuracy which ravishes into admiration
all men who have ever contemplated them. The curious adapting
of means to ends, throughout all nature, resembles exactly,
though it much exceeds, the productions of human contrivance;
of human designs, thought, wisdom, and intelligence. Since,
therefore, the effects resemble each other, we are led to
infer, by all the rules of analogy, that the causes also
resemble; and that the Author of Nature is somewhat similar
to the mind of man, though possessed of much larger faculties,
proportioned to the grandeur of the work which he has executed.
By this argument é posteriori, and by this argument alone, do
we prove at once the existence of a Deity, and his similarity
to human mind and intelligence.”
- The analogical respects pointed out include the following:
- Just as designed machines are created by human beings, so
likewise the designed universe is made by a creator.
- adaptation of ends to means in a machine : human
designer :: adaptation of ends to means in the world : world
designer
- effect of the machine : caused by human maker :: effect
of the universe : caused by universe maker

Further Reading:
”[Hume's] reply to the teleological argument may appear conclusive.
Yet some of the argument's proponets have responded that the existence of
God is not implied merely by the order in the world but, as George Berkeley
put it, by the ‘surprising magnificence, beauty , and perfection’
of that order. In other words, such a perfect world as ours could not be
either the work of an inferior deity or the outcome of impersonal natural
processes. Only an all-good, all-powerful, all-knowing creator could have
produced such a flawless masterpiece.” Steven M. Cahn, Puzzles
& Perplexities: Collected Essays (Lanham, MD: Lexington Books,
2007), 35.
