Neither ought I to doubt, seeing the _reallity_ which I perceive in my _Ideas_ is only an _objective reallity_, that therefore it must of necessity follow, that the same _reallity_ should be in the _causes_ of these _Ideas formally_. But I may conclude, that ’tis sufficient that this _reallity_ be in the very _causes_ only _objectively_. For as that _objective manner_ of _being_ appertains to the very _nature_ of an _Idea_, so that _formal manner_ of _being_ appertains to the very _nature_ of a _cause_ of _Ideas_, at least to the _first_ and _chiefest causes_ of them; For tho perhaps one _Idea_ may receive its birth from an other, yet we cannot proceed in _Infinitum_, but at last we must arrive at some _first Idea_, whose _cause_ is (as it were) an _Original copy_, in which all the _objective reallity_ of the _Idea_ is _formally contain’d_. So that I plainly discover by the _light_ of _nature_, that the _Ideas_, which are in me, are (as it were) _Pictures_, which may easily _come short_ of the _perfection_ of those things from whence they are taken, but cannot _contain_ any thing _greater_ or _more perfect_ then them: And the _longer_ and _more diligently_ I pry into these things, so much the more _clearly_ and _distinctly_ do I discover them to be _true_. But what shall I conclude from hence? Thus, that if the _objective reallity_ of any of my _Ideas_ be _such_, that it cannot be in me either _formally_ or _eminently_, and that therefore I cannot be the _cause_ of _that Idea_, from hence it necessarily Follows, that _I alone_ do not only _exist_, but that some other thing, which is _cause_ of that _Idea_, does _exist also_. But if I can find no _such Idea_ in me, I have no argument to perswade me of the _existence_ of any thing besides my self for I have diligently enquired, and hitherto I could discover no other _perswasive_. Some of these _Ideas_ there are (besides that which represents _my self_ to _my self_, of which in this place I cannot doubt) which represent to me, one of them a _God_, others of them _Corporeal_ and _Inanimate_ things, some of them _Angels_, others _Animals_, and lastly some of them which exhibite to me _men like my self_. As touching those that represent _Men_ or _Angels_ or _Animals_, I easily understand that they may be _made up_ of those _Ideas_ which I have of _my self_, of _Corporeal_ things, and of _God_, tho there were neither _man_ (but my self) nor _Angel_, nor _Animal_ in being.
