The same Hume who thus pleasantly rebuked 'most religious philosophers,' was himself a true Atheist. That he lacked faith in the supernatural must be apparent to every student of his writings, which abound with reflections far from flattering to the self-love of religionists, and little calculated to advance their cause. Many Deists have been called Atheists: among others Robert Owen and Richard Carlile, both of whom professed belief in something superior to nature, something acting upon and regulating matter, though not itself material. [11:1] This something they named _power_. But Hume has shown we may search 'in vain for an idea of power or necessary connection in all the sources from which we would suppose it to be derived. [11:2] Owen, Carlile, and other Atheists, falsely so called, supposed power the only entity worthy of deification. They dignified it with such appellations as 'internal or external cause of all existence,' and ascribed to it intelligence, with such other honourable attributes as are usually ascribed to 'deified, error.' But Hume astonished religious philosophers by declaring that, 'while we argue from the course of nature and infer a particular intelligent cause, which first bestowed, and still preserves order in the universe, we embrace a principle which is both uncertain and useless. It is uncertain, because the subject lies entirely beyond the reach of human experience. It is useless, because our knowledge of this cause being derived entirely from the course of nature, we can never, according to the rules of just reasoning, return back from the cause with any new inference, or making additions to the common and experienced course of nature, establish any principles of conduct and behaviour. [11:3] Nor did Hume affect to consider Christianity less repugnant to reason than any other theory or system of supernaturalism. Though confessedly fast in friendship, generous in disposition, and blameless in all the relations of life, few sincere Divines can forgive his hostility to their faith. And without doubt it was hostility eminently calculated to exhaust their stock of patience, because eminently calculated to damage their religion, which has nothing to fear from the assaults of ignorant and immoral opponents; but when assailed by men of unblemished reputation, who know well how to wield the weapons of wit, sarcasm, and solid argumentation, its priests are not without reason alarmed lest their house should be set _out_ of order.
