vice versâ. Or is it impossible that the contradictories of the necessary should be thus disposed? for, what, "is necessary to be" is "possible to be," since if not, negation would follow, as it is necessary either to affirm or deny, so that, if it is not possible to be, it is impossible to be, wherefore it would be impossible for that to be, which necessarily is, which is absurd, but the enunciation, "it is not impossible to be" follows the other, "it is possible to be," which again is followed by, "it is not necessary to be," whence it happens that what necessarily exists does not necessarily exist, which is absurd. But again neither does, "it is necessary to be" follow "it is possible to be," nor does the proposition, "it is necessary not to be," for to that, both, may occur, but whichever of these is true, those will be no longer true, for at one and the same time, it is possible to be, and not to be, but if it is necessary either to be or not to be, both, will not be possible. It remains therefore, that "it is not necessary not to be," follows "it is possible to be;" for this is also true in respect of what is necessary to be, since this becomes the contradiction of that proposition which follows, viz. "it is not possible to be;" as "it is impossible to be," and "it is necessary not to be," follow that, of which the negation is, "it is not necessary not to be." Wherefore these contradictions follow according to the above-mentioned mode, and nothing absurd results, when they are thus disposed.

Still it may be doubted whether "it is possible to be," follows "it is necessary to be," for if it does not follow, the contradiction will be consequent, namely, "it is not possible to be," and if a man should deny this to be a contradiction, it will be necessary to call, "it is possible not to be," a contradiction, both which are false in respect of necessary matter. Nay, on the contrary, it appears to be possible that the same thing should "be cut" and "not be cut," should "be" and "not be," so that what necessarily "is," may happen "not to be," which is false. Nevertheless it is evident that not every thing which can "be," and can "walk," is capable also of the opposites, for in some cases this is not true. In the first place,
