Sample text

A n d t r u t h applies i n one way to the first premiss, i n another to the second; it applies to the first ['Sickness holds of no health'] because 43 30 44 35 354,1 5 Translation 41 sickness has been taken, to the second ['Sickness holds of every h u m a n being'] because being sick has been. If being healthy is predi­ cated of what is sick, the proposition is contingent negative a n d not necessary, a n d so is the conclusion, since it is possible that being healthy holds of no h u m a n being; but i f h e a l t h is predicated the conclusion w i l l also be necessary negative, since by necessity no h u m a n being is health.

For they are misled because they assent to what is indeterminate as u n i v e r s a l as i f there were no difference between t a k i n g a premiss as u n i v e r s a l a n d t a k i n g it as indeterminate. 25 30 35 40 Chapter 34 353,1 5 41 47b40-48al5 Frequently deception because the terms i n a premiss are not set out well, [for example, i f A is health, B sickness, C h u m a n being. It is true to say that it is possible that A holds of no B (since h e a l t h holds of no sickness), and again that B holds of a l l C (since every h u m a n being is subject to sickness).

However, this has not been proved syllogistically, but certain premisses are missing for producing a syllogism; that is, what ought to be assumed is not assumed, but what is assumed is equivalent to premisses from w h i c h something could be proved syllogistically, but something has a l s o been omitted. There w i l l be a syllogism i f the assumptions are transformed into their equivalents a n d what is left out is added. F o r 'If a non-substance is done away w i t h , a substance is not done away w i t h ' is equivalent to its converse, ' A substance is done away w i t h by a substance', a n d this is equivalent to ' W h a t does away w i t h a sub­ stance w h e n it is done away w i t h is a substance'; for i f a substance is done away w i t h w h e n something is done away w i t h that t h i n g is a substance.
