Meditation 11.7-8

7. How vividly it strikes you that no other calling in life is so fitted for the practice of philosophy as this in which you now find yourself.

8. A branch cut off from the bough it belonged to cannot but be cut off also from the whole tree. Similarly a man, if severed from a single man, has fallen away from society as a whole. Now in the case of a branch, it is cut off by another agency, whereas man by his own act divides himself from his neighbour, when he hates him and turns from him, yet he does not realize that at the same time he has severed himself from the whole Commonwealth. Only there is this singular gift of Zeus who brought society together, that we are enabled to join again with the man we belong to, and again to become complements of the Whole. Yet, if it is often repeated, the effect of such separation is to make what separates difficult to unite and to restore. Generally speaking, too, the branch which originally grew with the tree and shared its transpiration, by remaining with it, is different from the branch which is engrafted again after being cut off, whatever gardeners may say.

'Grow together with them but do not share their doctrines.'
