But what the nature of necessity is, [Parmenides] did not define.

And Democritus was an acquaintance of Leucippus.

Now he makes statements similarly with Leucippus concerning elements, viz. plenitude and vacuum, denominating plenitude entity, and vacuum nonentity; and this he asserted, since existing things are continually moved in the vacuum. And he maintained worlds to be infinite, and varying in bulk; and that in some there is neither sun nor moon, while in others that they are larger than with us, and with others more numerous.
