β€˜The yes-man is your enemy, but your friend will argue with you.’

-Russian Proverb

β€˜Certainly then that people must needs be mad or strangely infatuated, that build the chief hope of their common happiness or safety on a single person; who, if he happen to be good, can do no more than another man; if to be bad, hath in his hands to do more evil without check, than millions of other men. The happiness of a nation must needs be firmest and certainest in full and free council of their own electing, where no single person, but reason only, sways.’

-John Milton
