Now therefore, if from this alone, _That I can frame the Idea of a Thing in my Mind_, it follows, _That whatever I clearly and distinctly perceive belonging to a thing_, does _Really belong to it_; Cannot I from hence draw an Argument to Prove the _Existence_ of a _God_? Certainly I find the _Idea_ of a _God_, or _infinitely perfect Being_, as _naturally_ in me, as the _Idea_ of any _Figure_, or _Number_; and I as _clearly_ and _distinctly_ understand that it appertains to his _Nature Always to Be_, as I know that what I can _demonstrate_ of a _Mathematical Figure_ or _Number_ belongs to the _Nature_ of that _Figure_ or _Number_: so that, tho all things which I have _Meditated_ upon these three or four days were not _true_, yet I may well be as _certain_ of the _Existence_ of a _God_, as I have hitherto been of _Mathematical Truths_. _Doubt._ Yet this Argument at first sight appears not so _evident_, but looks rather like a _sophism_; for seeing I am used in all other things to _Distinguish Existence_ from _Essence_, I can easily perswade my self that the _Existence_ of _God_ may be _distinguish’d_ from his _Essence_, so that I may _Imagine God_ not to _Exist_. _Solution._ But considering it more strictly, ’tis manifest, that the _Existence_ of _God_ can no more be _seperated_ from his _Essence_, then the _Equality_ of the _Three Angles_ to _two right ones_ can be _seperated_ from the _Essence_ of a _Triangle_, or then the _Idea_ of a _Mountain_ can be _without_ the _Idea_ of a _valley_; so that ’tis no less a _Repugnancy_ to think of a _God_ (that is, _A Being infinitely perfect_) who wants _Existence_ (that is, who wants a _Perfection_) then to think of a _Mountain_, to which there is _no Valley adjoyning_. _Doubt._ But what if I cannot imagine _God_ but as _Existing_, or a _Mountain without a Vally_? yet supposing me to think of a _Mountain with a Vally_, it does not from thence follow, that there _Is a Mountain_ in the World; so supposing me to think of a _God_ as _Existing_, yet does it not follow that _God Really Exists_. For my _Thought imposes_ no _necessity_ on Things, and as I may imagine a _Winged Horse_, tho no _Horse_ has _Wings_, so I may imagine an _existing God_, tho no _God exist_.
