Even among the earliest Stoics, Logic or Dialectic does not occupy the same place as in Plato: it is considered only as an instrument which is to be … - George Long

This is his [Marcus Aurelius Antoninus'] conclusion (II. 17): "What then is that which is able to conduct a man? One thing and only one, Philosophy. But this consists in keeping the divinity within a man free from violence and unharmed, superior to pains and pleasures, doing nothing without a purpose nor yet falsely and with hypocrisy, not feeling the need of another man's doing or not doing anything; and besides, accepting all that happens and all that is allotted, as coming from thence, wherever it is, from whence he himself came; and, finally, waiting for death with a cheerful mind as being nothing else than a dissolution of the elements of which every living being is compounded. But if there is no harm to the elements themselves in each continually changing into another, why should a man have any apprehension about the change and dissolution of all the elements [himself]? for it is according to nature; and nothing is evil that is according to nature."

We cannot work without matter to work on, and we must look round and see what there is. There is a material which will never fail. It is perhaps eternal, at least for us. It costs nothing, and it is everywhere. Raise your eyes on a clear night and look at the magnificent spectacle of the starry heavens... Would it be asking too much to ask masters occasionally to direct their pupils to the observation of the most splendid sight which the sons of men have had before their eyes ever since they have trod the earth?—to point out the position and tell the names of some of the brightest of these wondrous objects; to show the apparent motion of these bodies, to point out the polar star, and to lead by slow and sure steps to the conclusion which the genius of man has drawn from this apparent motion, and other considerations.

The last reflection of the Stoic philosophy that I have observed is in Simplicius' "Commentary on the Enchiridion of Epictetus." Simplicius was not a Christian, and such a man was not likely to be converted at a time when Christianity was grossly corrupted. But he was a really religious man, and he concludes his commentary with a prayer to the Deity which no Christian could improve.
