probabilities, we should then be able to estimate the actual value of any apparent probability relating to the latter province; but, as it is, our ability to make this estimate varies inversely as our inability to estimate our ignorance in this particular. And as our ignorance in this particular is total--_i.e._, since we cannot even approximately determine the proportion that subsists between the Conceivable and the Unknowable,--the result is that our ability to make the required estimate in any given case is absolutely _nil_. Sec. 40. I have purposely rendered this presentation in terms of the highest abstraction, partly to avoid the possibility of any one, whatever his theory of things may be, finding anything at which to object, and partly in order that my meaning may be understood to include all things which are beyond the range of possible knowledge. Most of all, therefore, must this presentation (if it contains anything of truth) apply to the question regarding the existence of Deity; for the _Ens Realissimum_ must of all things be furthest removed from the range of possible knowledge. Hence, if this presentation contains anything of truth--and of its rigidly accurate truth I think there can be no question--the assertion that the Self-existing Substance is a Personal and Intelligent Being, and the assertion that this Substance is an Impersonal and Non-Intelligent Being, are alike assertions wholly destitute of any assignable degree of logical probability, I say _assignable_ degree of logical probability, because that _some_ degree of such probability may exist I do not undertake to deny. All I assert is, that if we are here able to institute any such probability at all, we are unable logically to assign to it any determinate degree of value. Or, in other words, although we may establish some probability in a sense relative to ourselves, we are unable to know how far this probability is a probability in an absolute sense. Or again, the case is not as though we were altogether unacquainted with the Possible. Experience undoubtedly affords us some information regarding this, although, comparatively speaking, we are unable to know how much. Consequently, we must suppose that, in any given case, it is more likely that the Conceivable should be Possible than that the Inconceivable should be so, and that the Conceivably Probable should exist than that the Conceivably Improbable should do so: in neither case, however, can we know _what degree_ of such likelihood is present.
