Neither was it without Reason that _I_ Judged, _That Body_ (which by a _peculiar right I_ call my _Own_) to be _more nighly_ appertaining to _Me_ then any _other Body_. For from It, as from other _Bodies_, _I_ can never be _seperated_, _I_ was _sensible_ of all _Appetites_ and _Affections in It_ and _for It_, and lastly _I_ perceived _pleasure_ and _Pain_ in its Parts, and not in any other Without it. But why from the _sense_ of Pain a certain _Grief_, and from the _sense_ of _pleasure_ a certain _Joy_ of the _Mind_ should arise, or Why that _Gnawing_ of the _stomach_, Which _I_ call _Hunger_, should put me in mind of _Eating_, or the _driness_ of my _Throat_ of _Drinking_, _I_ can give no other Reason but _that I am taught so by Nature_. For to my thinking there is no _Affinity_ or _Likeness_ between that _Gnawing_ of the _Stomach_, and the desire of _Eating_, or between the _sense_ of _Pain_, and the _sorrowful thought_ from thence arising. But in this as in all other _judgments_ that I made of _sensible objects_, I seem’d to be taught by _Nature_, for I first perswaded my self that things were _so_ or _so_, before ever I enquired into a Reason that may prove it. [Sidenote: _The Reasons why I doubted my senses._] [Sidenote: _Medit. I._] But afterwards I discover’d many experiments, wherein my _senses_ so grosly deceived me, that I would never trust them again; for Towers which seem’d _Round_ a far off, nigh at hand appear’d _square_, and _large_ Statues on their tops seem’d _small_ to those that stood on the ground; and in numberless other things, I perceived the _judgements_ of my _outward senses_ were _deceived_: and not of my _outward_ only, but of my _inward senses_ also; for what is more _intimate_ or _inward_ than _Pain_? And yet I have heard from those, whose Arm or Leg was cut off, that they have felt _pain_ in that part which they _wanted_, and therefore I am not _absolutely certain_ that any part of me is affected with _pain_, tho I _feel pain_ therein. To these I have lately added two very _general Reasons_ of _doubt_; The first was, that while I was _awake_, I could not believe my self to perceive any thing, which I could not think my self sometimes to perceive, tho I were _a sleep_; And seeing I cannot believe, that what I seem to perceive in my _sleep_ proceeds from _outward Objects_, what greater Reason have I to think so of what I perceive whilst I am _awake_? The other Cause of Doubt was, that seeing I know not the _Author_ of my _Being_ (or at least I then _supposed_ my self not to know him) what reason is there but that I may be so ordered by _Nature_ as to be _deceived_ even in those things which appear’d to me most _true_. And as to the _Reasons_, which induced me to give _credit_ to _sensible_ Things, ’twas easie to return an answer thereto, for finding by experience, that I was impelled by _Nature_ to many Things, which _Reason_ disswaded me from, I thought I should not far trust what I was taught by _Nature_.
