In this podcast we discussed the desirability of consistently taking the same position, and unfortunately I was unable to come up with the exact quote from Diogenes Laertius I was trying to recall. Here's the reference I was thinking of as to being the same both awake and asleep. I feel sure there are others in other texts referencing honesty and clear-speaking:
[121] He will erect statues of others, but whether he had one himself or not, he would be indifferent. Only the Wise man could discourse rightly on music and poetry, but in practice he would not compose poems. One wise man is not wiser than another. He will be ready to make money, but only when he is in straits and by means of his philosophy. He will pay court to a king, if occasion demands. He will rejoice at another’s misfortunes, but only for his correction. And he will gather together a school, but never so as to become a popular leader. He will give lectures in public, but never unless asked; he will give definite teaching and not profess doubt. In his sleep he will be as he is awake, and on occasion he will even die for a friend.
