effect of CUSTOM, not of REASONING.” Cause means only “customary conjunction.” Then, towards the conclusion of the same chapter, he says, “There is a kind of pre-established harmony between the course of nature and the succession of our ideas; and though the Powers and Forces by which the former is governed be wholly unknown to us, yet our thoughts and conceptions have still, we find, gone on in the same train with the other works of nature. CUSTOM is that principle by which this correspondence has been effected.” Cognate with these chapters on Causation are some discussions that follow on the idea of power or necessary connexion, in which he maintains that this idea is not copied either from the observation of the operation of forces {312} in the external world or in the world of volition within us; that in all cases what we know is only “the frequent CONJUNCTION of objects, not their connexion;” “all events seem entirely loose and separate; and at bottom we have no idea of connexion or power at all, and these words are absolutely without any meaning;” and, philosophically expressed, “the sentiment or impression from which we form the idea of power or necessary connexion,” is only “the customary transition of the imagination from one object to its usual attendant.” And so “we may define a CAUSE to be one object followed by another, and where all the objects similar to the first are followed by objects similar to the second.” Lastly, to crown this whole elaborate edifice of Scottish atheism, we have, in the chapter on “Providence and a Future State,” the following sentences:--“When we infer any particular cause from an effect, we must proportion the one to the other, and can never be allowed to ascribe to the cause any qualities but what are exactly sufficient to produce the effect. Allowing, therefore, the gods to be the Authors of the existence or order of the universe, it follows that they possess that precise degree of power, intelligence, and benevolence which appears in their workmanship; but nothing further can be proved. The supposition of further attributes is mere hypothesis.” This argument is levelled against the perfection of the Divine workmanship and attributes. He then proceeds to annihilate, as he conceives, the Socratic argument from design in the following fashion:--“If you saw a half-finished building, surrounded with heaps of brick and stone and mortar, and all the instruments of masonry, {313} you might justly infer from this effect that it was a work of design and contrivance; and in reference to works of human art this reasoning is good, because _man is a being whom we know by experience_. But the case is not the same with our reasonings from the works of Nature. The Deity is known to us only by his productions, and is a single Being in the universe not comprehended under any species or genus, from whose experienced attributes or qualities we can by analogy infer any attribute or quality in him.
