Six metaphysical meditations · René Descartes
OBJECT. VI.
Moreover _Affirmation_ and _Negation_ are not without a _voice_ and _words_, and hence ’tis that Brutes can neither _affirme_ or _deny_ not so much as in their Thought, and consequently neither can they judge. But yet the same thought may be in a beast as in a Man; for when we _affirme_ that a Man runs, we have not a _thought_ different from what a Dog has when he sees his Master running; _Affirmation_ therefore or _Negation_ superadds nothing to _meer thoughts_, unless perhaps it adds this thought, that the _names_ of which an _Affirmation_ consists are (to the Person _affirming_) the _Names_ of the _same thing_; and this is not to comprehend in the _thought_ more then the _likeness_ of the _thing_, but it is only comprehending the same _likeness twice_. ’Tis self evident, That ’tis one thing to _see_ a Lion and at the same time to _fear_ him, and an other thing _only_ to _see_ him. So ’tis one thing to _see_ a Man Running, and an other thing to _Affirme_ within my self (which may be done without a voice) That I _see_ him. But in all this objection I find nothing that requires an Answer.
