Someone, reaching here, might ask how the account given is s t i l l the definition of syllogism i f there are also other arguments i n w h i c h 31 15 20 25 30 35 350,1 5 Translation 'some things being posited something different from what is posited follows by necessity .

For, i f these things are posited, it is necessary that a part of a substance be a substance, but this has not been inferred syllogistically through the premisses; rather premisses are missing]. 17 18 10 H e means in some cases; he says that i n some cases it is not difficult to recognize what is needed to make the syllogism whole and what has been assumed superfluously, as i n the case of the arguments we have just spoken about (since i n these cases it is clear what has been omitted). B u t also i n cases i n w h i c h something different has been inferred as conclusion a n d not what follows from what is assumed, as i n the case of the argument put forward by E p i c u r u s w h i c h says: 15 D e a t h is nothing to us; for what has been dissolved lacks percep­ tion; a n d what lacks perception is nothing to u s .

So i f we substitute being healthy and being sick for health a n d sickness, the proposition ' B y necessity being healthy of no one who is sick' w i l l not be a true necessary u n i v e r s a l negative one. 35 355,1 5 42 10 15 20 Translation It is also possible i n the case of this combination to say the same thing: that the premiss w h i c h says that health is said of every h u m a n being is not true without qualification because it is not even possible that ' E v e r y h u m a n being is health' is true.
