system as this, the earth shrinks into insignificance. Can its concerns engage the attention of him who made the whole? But again, this whole Solar System itself, with all its orbits and planets, shrinks into a mere point, when compared with the nearest fixed star. And again, the distance which lies between us and such stars, shrinks into incalculable smallness, when we journey in thought to other fixed stars. And again, and again, the field of our previous contemplation suffers an immeasurable contraction, as we pass on to other points of view. 5. And in all these successive moves, we are still within the dominions of the same Creator and Governor; and at every move, we are brought, we may suppose, to new bodies of his subjects, bearing, in the expansion of their number, some proportion to the expanse of space which they occupy. And if this be so, how shall the earth, and men, its inhabitants, thus repeatedly annihilated, as it were, by the growing magnitude of the known Universe, continue to be anything in the regard of Him who embraces all? Least of all, how shall men continue to receive that special, persevering, providential, judicial, personal care, which religion implies; and without the belief of which, any man who has religious thoughts, must be disturbed and unhappy, desolate and forsaken? 6. Such are, I conceive, the thoughts of many persons, under the influence of the astronomical views which Chalmers refers to as being sometimes employed against religious belief. Of course, it is natural that the views which are used by unbelievers as arguments against religious belief, should create difficulties and troubles in the minds of believers; at least, till the argument is rebutted. And of course also, the answers to the arguments, considered as infidel arguments, would operate to remove the difficulties which believers entertain on such grounds. Chalmers' reasonings against such arguments, therefore, will, so for as they are valid, avail to relieve the mental trouble of believers, who are perplexed and oppressed by the astronomical views of which I have spoken; as well as to confute and convince those who reject religion, on such astronomical grounds. It may, however, as I have said, be of use to deal with these difficulties rather as difficulties of religious men, than as objections of irreligious men; to examine rather how we can quiet the troubled and perplexed believer, than how we can triumph over the dogmatic and self-satisfied infidel. I, at least, should wish to have the former, rather than the latter of these tasks, regarded as that which I propose to myself. I shall hereafter attempt to explain more fully the difficulties which the doctrine of the Plurality of Worlds appears to some persons to throw in the way of Revealed Religion; but before I do so, there is one part of Chalmers' answer, bearing especially upon Natural Religion, which it may be proper to attend to.
