* 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.
ANSWER.
I have here Explain’d the Difference between Imagination, and the Meer Conception of the Mind, by reckoning up in my Example of the Wax, what it is therein which we Imagine, and what it is that we conceive in our Mind only: but besides this, I have explained in an other Place How we understand one way, and Imagine an other way One and the same Thing, suppose a Pentagone or Five sided Figure.
There is in Ratiocination a Conjunction not of Words, but of Things signified by Words; And I much admire that the Contrary could Possibly enter any Mans Thoughts; For Who ever doubted but that a Frenchman and a German may argue about the same Things, tho they use very Differing Words? and does not the Philosopher Disprove himself when he speaks of the Agreements which at pleasure we have made about the significations of Words? for if he grants that something is Signified by Words, Why will he not admit that our Ratiocinations are rather about this something, then about Words only? and by the same Right that he concludes the Mind to be a Motion, he may Conclude Also that the Earth is Heaven, or What else he Pleases.
