* _It remains therefore for me to Confess that I cannot Imagine what this
Wax is, but that I conceive in my mind What it is._
There is a great Difference between _Imagination_ (that is) having
an _Idea_ of a Thing, and the _Conception of the Mind_ (that is) a
_Concluding_ from _Reasoning_ that a thing _Is_ or _Exists_. But
_Des-Cartes_ has not Declared to us in what they Differ. Besides,
the Ancient Aristotelians have clearly deliver’d as a Doctrine, that
_substance_ is not _perceived_ by _sense_ but is _Collected_ by
_Ratiocination_.
But what shall we now say, if perhaps _Ratiocination_ be nothing Else but
a _Copulation_ or _Concatenation_ of _Names_ or _Appellations_ by this
Word _Is_? From whence ’twill follow that we _Collect_ by _Reasoning_
nothing _of_ or _concerning_ the _Nature_ of _Things_, but of the _names_
of _Things_, that is to say, we only discover whether or no we _joyn_ the
_Names_ of _Things_ according to the _Agreements_ which at Pleasure we
have made concerning their _significations_; if it be so (as so it may
be) _Ratiocination_ will depend on _Words_, _Words_ on _Imagination_,
and perhaps _Imagination_ as _also Sense_ on the _Motion_ of _Corporeal
Parts_; and so the _Mind_ shall be nothing but _Motions_ in some Parts of
an _Organical Body_.
