Besides this, I Consider that this _Power_ of _Imagination_ which is in me (as it differs from the _Power_ of _Understanding_) does not appertain to the _Essence_ of _Me_, that is, of _my mind_, for tho I _wanted_ it, yet certainly I should be the _same He, that_ now _I am_: from whence it seems to follow, that it depends on something _different_ from _my self_; and I easily perceive that if any _Body_ whatever did _Exist_, to which my _Mind_ were so _conjoyn’d_, that it may Apply it self when it pleased to _Consider_, or (as it were) _Look_ into _this Body_; From hence, I say, I perceive _It may so be_, that by this very _Body_ I may _Imagine Corporeal Beings_: So that this _Manner_ of _Thinking_ differs from _pure Intellection_ only in this, that the _Mind_, when it _Understands_, does as it were turn _it self_, to _it self_, or _Reflect_ on it self, and _beholds_ some or other of those _Ideas_ which are in it self; But when it _Imagines_, it _Converts_ it self upon _Body_, and therein _beholds_ something Conformable to that _Idea_, which it hath _understood_, or _perceived_ by _Sense_. But ’tis to be remembred, that I said, I easily conceive Imagination _May be_ so performed, supposing _Body_ to _Exist_. And because no so convenient manner of Explaining it offers it self, from thence I _probably_ guess, that _Body_ does _Exist_. But this I only say _probably_, for tho I should accurately search into all the Arguments drawn from the _distinct Idea_ of _Body_, which I find in my _Imagination_, yet I find none of them, from whence I may _necessarily_ conclude, _that Body does Exist_. But I have been accustomed to _Imagine_ many other things besides that _Corporeal Nature_ which is the _Object_ of _pure Mathematicks_; such as are, _Colours_, _Sounds_, _Tasts_, _Pain_, &c. but none of these so _distinctly_. And because I perceive these better by _Sense_, from Which by the Help of the _Memory_ they come to the _Imagination_, that I may with the Greater advantage treat of them, I ought at the same time to Consider _Sence_, and to try whether from what I perceive by that way of _Thought_, which I call _Sense_, I can deduce any certain Argument for the _Existence_ of _Corporeal Beings_. And first I will here reflect with my self, what those things were, which being perceived by _Sence_ I have heretofore thought _True_, and the _Reasons_ why I _so thought_: I will then enquire into the _Reasons_ for which I afterwards _doubted_ those things. And last of all I will consider what I _ought_ to _think_ of those Things at _Present_. [Sidenote: _The Reasons why I Trusted my Senses._]
