Philosophy of religion
From an early age Hume was preoccupied with re-
ligion and science. Before he was twenty, he set
down in a notebook “the gradual progress” of his
thoughts on theism: “It begun with an anxious
search after arguments to confirm the common
opinion: Doubts stole in, dissipated, return’d, were
again dissipated, return’d again; and it was a per-
petual struggle of a restless imagination against in-
clination, perhaps against reason.” It therefore is
unsurprising that the Treatise as originally written
contained several antireligious sections and re-
marks that Hume prudently removed before publi-
cation. In 1737 he told a friend that he was “cas-
trating” his manuscript, or “cutting off its nobler
parts” so that it would “give as little offence as pos-
sible.” He deleted an essay on miracles and proba-
bly also one on the immortality of the soul. But
notwithstanding these precautions, the very first
notice of the work warned readers of its “evil in-
tentions,” evident from the book’s motto alone:
“Seldom are men blessed with times in which they
may think what they like, and say what they think”.
Hume must have realized that a discerning
reader of the Treatise would have detected echoes
of principles and doctrines prominent in the works
of Pierre Bayle (1647–1706), Anthony Collins
(1676–1729), Thomas Hobbes (1588–1679), Baruch
Spinoza (1632–1677), and other “free thinkers.” He
therefore should not have been surprised when, in
1745, he applied for a chair in philosophy at the
University of Edinburgh, and the local clergy de-
feated his candidacy by charging him with advo-
cating “universal scepticism” and “downright athe-
ism.” They also accused him of “denying the
immortality of the soul” and of “sapping the foun-
dations of morality, by denying the natural and es-
sential difference between right and wrong, good
and evil, justice and injustice; making the differ-
ence only artificial, and to arise from human con-
ventions and compacts.” Hume defended himself
against these misunderstandings and misrepresen-
tations, but thereafter his writings became increas-
ingly antireligious.
In 1748 Hume published his essay on miracles,
in which he argued that there is no reason to be-
lieve that any miracle has ever occurred. His argu-
ment was attacked by many contemporaries, in-
cluding William Adams, John Douglas, Richard
Price, and George Campbell, whose criticisms are
still worth reading. In the same collection Hume
devoted an essay to arguing that there is no reason
to believe in a particular providence or a future
state. This attack on the argument from design was
elaborated in Hume’s posthumously published Di-
alogues Concerning Natural Religion (1779), which
is modelled upon Cicero’s De Natura Deorum.
The historian Edward Gibbon (1737–1794) re-
garded the Dialogues as “the most profound, the
most ingenious, and the best written of Hume’s
philosophic works.” It remains the classic discus-
sion of the argument from design (or argument a
posteriori), and some regard it as the most impor-
tant work in the philosophy of religion in English.
Had William Paley (1743–1805) carefully studied it,
he might never have written Evidences of Chris-
tianity (1794) or Natural Theology (1802). Along
the way Samuel Clarke’s (1675–1729) a priori ar-
gument for the existence of God is refuted, and the
objections to theism from the existence of evil are
forcefully presented.
The Dialogues involves three disputants: the or-
thodox rationalist theologian Demea, the “careless
sceptic” Philo, and the scientific theologian Clean-
thes, who frequently echoes Bishop Butler’s Anal-
ogy of Religion (1736). Though the argument from
design is subjected to sustained criticism, and the
attentive reader may be convinced that the canons
of scientific reasoning do not issue in theism, at the
end Cleanthes seems to emerge as the winner, lead-
ing some mistakenly to conclude that Cleanthes
speaks for Hume himself. But the Dialogues were
so “artfully written” that Philo the sceptic only ap-
pears to be “silenced.” In a private letter Hume said
that he objected “to everything we commonly call
religion, except the Practice of Morality, and the
Assent of the Understanding to the Proposition that
God exists.” But in the Dialogues the concept of
God is virtually evacuated of all meaning, so such
“assent” amounts to little or nothing. Hume’s friend
Dr. Hugh Blair, who advised against publishing the
Dialogues during Hume’s lifetime, remarked that
they are “exceedingly elegant” and “bring together
some of his most exceptional reasonings, but the
principles themselves were in all his former works.”
Most scholars now hold that Philo represents Hume
himself. Hume denied that he was an atheist or a
deist, so he is perhaps best viewed as a not-so-
careless sceptic.
In the Treatise Hume argued that morality is
not founded on reason, but on passion. Reason
