Thou canst pass thy life in an equable flow of happiness, if thou canst go by the right way, and think and act in the right way. These two things are common both to the soul of God and to the soul of man, and to the soul of every rational being, not to be hindered by another; and to hold good to consist in the disposition to justice and the practice of it, and in this to let thy desire find its termination.
As the nature of the universal has given to every rational being all the other powers that it has, so we have received from it this power also. For as the universal nature converts and fixes in its predestined place everything which stands in the way and opposes it, and makes such things a part of itself, so also the rational animal is able to make every hindrance its own material, and to use it for such purposes as it may have designed.
