"Time then has come into being along with the universe, that being generated together, together they may be dissolved, should a dissolution of them ever come to pass; and it was made after the pattern of the eternal nature, that it might be as like to it as was possible. For the pattern is existent for all eternity; but the copy has been and is and shall be throughout all time continually. So then this was the plan and intent of God for the generation of time; the sun and the moon and five other stars which have the name of planets have been created for defining and preserving the numbers of time. ...and a month is fulfilled when the moon, after completing her own orbit, overtakes the sun; a year, when the sun has completed his own course. But the courses of the others men have not taken into account, save a few out of many... they do not know that time arises from the wanderings of these, which are incalculable in multitude and marvellously intricate. None the less however can we observe that the perfect number of time fulfils the perfect year at the moment when the relative swiftnesses of all the eight revolutions accomplish their course together and reach their starting-point, being measured by the circle of the same and uniformly moving. In this way then and for these causes were created all such of the stars as wander through the heavens and turn about therein, in order that this universe may be most like to the perfect and ideal animal by its assimilation to the eternal being."

“Doing what is for the good of the people, this must be the truest criterion of right government, in accordance with which the wise and good man will govern the affairs of his subjects. Just as the captain of a ship keeps watch for what is at any moment for the good of the vessel and the sailors, not by writing rules, but by making his science his law, and thus preserves his fellow voyagers, so may not a right government be established in the same way by men who could rule by this principle, making science more powerful than the laws? And whatever the wise rulers do, they can commit no error, so long as they maintain one great principle and by always dispensing absolute justice to them with wisdom and science are able to preserve the citizens and make them better than they were, so far as that is possible.”

“Law could never, by determining exactly what is noblest and must just for one and all, enjoin upon them that which is best; for the differences of men and of actions and the fact that nothing, I may say, in human life is ever at rest, forbid any science whatsoever to promulgate any simple rule for everything and for all time… So, that which is persistently simple is inapplicable to things which are never simple.”

“The greatest and noblest conceptions have no image wrought plainly for human vision, which he who wishes to satisfy the mind of the inquirer can apply to some one of his senses and by mere exhibition satisfy the mind. We must therefore endeavor by practice to acquire the power of giving and understanding a rational definition of each one of them; for immaterial things, which are the noblest and greatest, can be exhibited by reason only, and it is for their sake that all we are saying is said. But it is always easier to practice in small matters than in greater ones.”

“It is difficult to set forth any of the greater ideas, except by the use of examples; for it would seem that each of us knows everything that he knows as if in a dream and then again, when he is as it were awake, knows nothing of it all.”

“The attempt to separate everything from everything else is not only not in good taste but also shows that a man is utterly uncultivated and unphilosophical. The complete separation of each thing from all is the utterly final obliteration of all discourse. For our power of discourse is derived from the interweaving of the classes or ideas with one another.”

“We certainly must contend by every argument against him who does away with knowledge or reason or mind and then makes any dogmatic assertion about anything. The philosopher, who pays the highest honor to these things, must necessarily, as it seems, because of them refuse to accept the theory of those who say the universe is at rest, whether as a unity or in many forms, and must also refuse utterly to listen to those who say that being is universal motion; … he must say that being and the universe consist of both.”
