Remember to act always as if you were at a symposium. When the food or drink comes around, reach out and take some politely; if it passes you by don't try to pulling it back. And if it has not reached you yet, don't let your desire run ahead of you, be patient until your turn comes.

[14] What am I to do, then? Accept the false conclusion? [15] And how is that possible? Then should I say that I was wrong to accept the premisses? No, this isn’t permissible either. Or say: That doesn’t follow from the premisses? But that again isn’t permissible. [16] So what is one to do in such circumstances? Isn’t it the same as with debts? Just as having borrowed on some occasion isn’t enough to make somebody a debtor, but it is necessary in addition that he continues to owe the money and hasn’t paid off the loan; likewise, our having accepted the premisses isn’t enough to make it necessary for us to accept the inference, but we have to continue to accept the premisses.

Remember that you must behave in life as at a dinner party. Is anything brought around to you? Put out your hand and take your share with moderation. Does it pass by you? Don’t stop it. Is it not yet come? Don’t stretch your desire towards it, but wait till it reaches you.
