It is unpardonable conceit not to laugh at your own jokes. Joking is undignified; that is why it is so good for one's soul. Do not fancy you can be a detached wit and avoid being a buffoon; you cannot. If you are the Court Jester you must be the Court Fool.
For I did not know that the soul needs to be enlightened by light from outside itself, so that it can participate in truth, because it is not itself the nature of truth.
But if nothing but soul, or in soul mind, is qualified to count, it is impossible for there to be time unless there is soul, but only that of which time is an attribute, i.e. if change can exist without soul.
