Meditations 6.42

We are all working together to one end, some with knowledge and design, and others without knowing what they do; as men also when they are asleep, of whom it is Heraclitus, I think, who says that they are laborers and co-operators in the things which take place in the universe. But men co-operate after different fashions: and even those co-operate abundantly, who find fault with what happens and those who try to oppose it and to hinder it; for the universe had need even of such men as these. It remains then for thee to understand among what kind of workmen thou placest thyself; for he who rules all things will certainly make a right use of thee, and he will receive thee among some part of the co-operators and of those whose labors conduce to one end. But be not thou such a part as the mean and ridiculous verse in the play, which Chrysippus speaks of.

Marcus Aurelius, Meditations 6.42, translated by George Long

We are all fellow-workers towards the fulfilment of one object, some of us knowingly and intelligently, others blindly; just as Heraclitus, I think, says that even when they sleep men are workers and fellow-agents in all that goes on in the world. One is a co-agent in this, another in that, and in abundant measure also he that murmurs and seeks to hinder or disannul what occurs. For the Universe had need of such men also. It remains then for thee to decide with whom thou art ranging thyself. For He that controls the Universe will in any case put thee to a good use and admit thee to a place among his fellow-workers and coadjutors. But see that thou fill no such place as the paltry and ridiculous line in the play which Chrysippus mentions.
