creation; and again those who urge that it will be destroyed are at strife with those who affirm that it is indeed perishable by nature but that it never will be destroyed, because it is held together by a more powerful chain, the will of the Creator. And again, those who affirm that there is nothing self-existent, but that everything has been created, are at variance with those who are of a contrary opinion. Those too, who say that man is the measure of all things, differ from those who would restrain the judicial faculties of the outward senses and of the intellect. And, in short, to sum up all these differences in a few words, those who represent everything as incomprehensible are at variance with those who say that a great number of things are properly understood. (247) And the sun, and the moon, and the whole heaven, and the earth, and the air, and the water, and all the things that are connected with them, afford subject for strife and contention to those who are fond of examining into such subjects, and who investigate their essences, and distinctive qualities, and changes, and alterations, and moreover their origin and the method of their destruction; and making no superficial investigation into the magnitude and motion of the heavenly bodies, they adopt all sorts of different opinions, never agreeing together, until some man, who is at the same time skilful at disentangling controversies and calculated to judge, takes his seat on the tribunal, and comes to a clear perception of the progeny of each individual’s soul, and discards those which do not deserve to be maintained, and preserves those which are good, and which he pronounces worthy of suitable providential care. (248) And all the controversies of philosophy are full of disagreement, since the truth escapes the intellect which is given to plausibilities and conjectures: for it is the very difficulty of discovering and seizing hold of the nature of truth that, in my opinion, has given rise to so many quarrels.
