But if Mr. Mill is unjust towards the distinction between Knowledge and Belief, as held by Sir W. Hamilton, he makes ample amends to the injured theory in the next chapter, by enlarging the province of credibility far beyond any extent which Hamilton would have dreamed of claiming for it. Conceivability or inconceivability, he tells us, are usually dependent on association; and it is quite possible that, under other associations, we might be able to conceive, and therefore to believe, anything short of the direct contradiction that the same thing is and is not. It is not in itself incredible, that a square may at the same time be round, that two straight lines may enclose a space, or even that two and two may make five.[AZ] But whatever concessions Mr. Mill may make on this point, he is at least fully determined that Sir W. Hamilton shall derive no benefit from them; for he forthwith proceeds to charge Sir William with confusing three distinct senses of the term _conception_--a confusion which exists solely in his own imagination,[BA]--and to assert that the Philosophy of the Conditioned is entirely founded on a mistake, inasmuch as infinite space on the one hand, and, on the other, both an absolute minimum and an infinite divisibility of space, are perfectly conceivable. With regard to the former of these two assertions, Mr. Mill's whole argument is vitiated, as we have already shown, by his confusion between _infinite_ and _indefinite_; but it is worth while to quote one of his special instances in this chapter, as a specimen of the kind of reasoning which an eminent writer on logic can sometimes employ. In reference to Sir W. Hamilton's assertion, that infinite space would require infinite time to conceive it, he says, "Let us try the doctrine upon a complex whole, short of infinite, such as the number 695,788. Sir W. Hamilton would not, I suppose, have maintained that this number is inconceivable. How long did he think it would take to go over every separate unit of this whole, so as to obtain a perfect knowledge of the exact sum, as different from all other sums, either greater or less?" [AZ] In reference to this last paradox, Mr. Mill quotes from _Essays by a Barrister_: "There is a world in which, whenever two pairs of things are either placed in proximity or are contemplated together, a fifth thing is immediately created and brought within the contemplation of the mind engaged in putting two and two together.... In such a world surely two and two would make five. That is, the result to the mind of contemplating two twos would be to count five." The answer to this reasoning has been already given by Archdeacon Lee in his Essay on Miracles. The "five" in this case is not the sum of two and two, but of two and two _plus_ the new creature, _i.e._, of two and two _plus_ one.
