His Thilofophy.
* Lib. ^ Q^Trabo and. Laertius affirm hewasaD/ flkcHl. O leUick'., Tho Dialefticks (faith i Cicero)
teach in their Elements wJ?ether a connex (a propofition which hath the conjun£l:ion if) oe
• true or fdfe •, as this.^if it be day.^ it is light how 3 much is it controverted? Diodorus is of one opi¬ nion., Philo of another., Chrylippus of a third:
That Diodorus laboured much herein, appears from an Epigram of Callimachus, cited and ex-
; Adverf.Grm Plained by ^ Sextus Empiricus.
Concerning thefe propofitions, the Dilagree ment of Diodorus from Lhilo and Chryjippusf al ready mentioned by Cicero) is thus explained by t P^rrh.lhp.2. ^ ‘5’£’Ar/«f Empiricus 5 But when faith hepr how it ’ ' followeth they dif agree among themfelvesymdthofe things whereby they deter jnine a confequence to be judgedpppugn one another : as fhidofaidft is a true Conm\,when it beginneth not from true, and ended in falfe. So that according to his opini¬ on, a true Connex may be true fever al ways, a falfe only one way. Lor when it beginneth from true, and endeth in true, it is true-,as this, Jf it be day, it is light Again,when it beginneth from falfe and end¬ eth infalfe,it is true: As xhis,lfthe Eaj;th flies,the earth hat h wings. Likewife that which ' beginneth. fromj-alfe-,and endeth in'true is true-, as ihis,if the Earth flies it is Earth : That only is true vohich beginneth from true, and endeth in falfe. Such is this, if it he day it is night. Eor if it be day, that it is day is true , nrhich is the Antecedent.
But that it is night is fife, which was the Con- Jequent. Diodorus faith, that is a true Con¬ nex which is not contingent, beginning from true, and ending in fdje. This is contrary to the opinion of?Yd\o,forfuchaCom\Qyi as this,m magnitude finite.
if it be day Idifcourfe, and if at prefent it be day, and I difcourfe,is according to Philo’s opinion, a true Connex : for it begins from true, it is day, and ends in true, I d fcourje. But according to the opinion of Diodorus it is falfe : for it may fo happen, that though it begin from true, to wit,
^it is day, yet it may end in falfe, to wit, that I difcourfe when I am Jilent. Thus by Contin¬ gency it may begin in true, and end in falfe -, for before I began to difcourfe, it began from true, to wit,it is day.'but endedin fafe,to wit f difcourfe.
And.again, ^ for that we examine not many o- ^ pinions concerning a Connex, us fay that Con- * nex is in it felf right, which beginneth not from true, and endeth in falfe. This, if there be motion, there is vacuity according to Epicurus’s opinion, beginning from true, to wit, there is motion, and ending in true, will be true. According to theVt- ripateticks, beginning jrom true, to wit, there is motion, and ending in falfe, to wit, there is va- cuity,willbe falfe -, according toDiiodiQiViS, begin- ^
ning from falfe -to wit, there is motion, and end- ° ing infalfe,to wit, there is vacuity, will be -true, for the affumption,to wit, there is motion, he de¬ nies as falfe,
t Some affirm, he invented the vailed and tLacn. horned Arguments (of which already in the life oi'Eubulides f Alexander Aphroffeus, faith he,, ifed Kvexivovlcc^o-yoy ^ the dominative Argument : prhr, '
