But When I was exercised about any single and easie Proposition in Arithmetick or Geometry, as that two and three added make five, Did not I Perceive them _Clearly_ enough to make me affirm them True? Truly concerning these I had no other Reason afterwards to _Doubt_, but That I thought Perhaps there may be a _God_ who might have so created me, that I should be _Deceived_ even in those things which seem’d most _Clear_ to me. And as often as this Pre-conceived opinion of _Gods great Power_ comes into my Mind, I cannot but Confess that he may easily cause me to Err even in those things which I Think I perceive most _Evidently_ with my Mind; yet as often as I Consider the Things themselves, which I Judge my self to perceive so _Clearly_, I am so fully Perswaded by them, that I easily Break out into these Expressions, Let Who can Deceive Me, yet he shall never Cause me _Not to Be_ whilst _I think that I Am_, or that it shall ever be True, _that I never was_, Whilst at Present ’tis True _that I am_, or Perhaps, that Two and Three added make More or Less then Five; for in These things I Percieve a Manifest Repugnancy; And truely seeing I have no reason to Think any _God_ a _Deceiver_, Nor as yet fully know Whether there Be _any God_, or _Not_, ’Tis but a slight and (as I may say) Metaphysical Reason of Doubt, which depends only on that opinion of which I am not yet Perswaded. Wherefore That this Hindrance may be taken away, When I have time I ought to Enquire, Whether there _Be a God_, And if there be One, Whether he can be a _Deceiver_, For whilst I am _Ignorant_ of this, I cannot possibly be fully _Certain_ of any Other thing. But now Method seems to Require Me to Rank all My Thoughts under certain Heads, and to search in Which of them _Truth_ or _Falshood_ properly Consists. Some of them are (as it were) the _Images_ of Things, and to these alone the Name of an _Idea_ properly belongs, as When I think upon a Man, A Chimera or Monster, Heaven, an Angel, or _God_. But there are others of them, that have _superadded Forms_ to them, as when I Will, when I Fear, when I Affirm, when I Deny. I know I have alwayes (when ever I think) some certain Thing as the _subject_ or _object_ of my Thought, but in this last sort of thoughts there is something _more_ which I Think upon then Barely the likeness of the Thing. And of these Thoughts some are called _Wills_ and _Affections_, and Others of them _Judgments_. Now as touching _Ideas_, if they be Consider’d alone as they are in themselves, without _Respect_ to any other Things, they cannot Properly be _false_; for Whether I _Imagine_ a Goat or a Chimera, ’tis as _Certain_ that I _Imagine_ one as t’other. Also in the _Will_ and _Affections_ I need not Fear any _Falshood_, For tho I should _Wish_ for _evil Things_, or Things that are Not, it is not therefore _Not true_ that I Wish for them.
