“And if the government of the countenance be of such effect, much more is that of the speech, and other carriage appertaining to conversation; the true model whereof seemeth to me well expressed by Livy, though not meant for this purpose: Ne aut arrogans videar, aut obnoxius; quorum alterum est àlienæ libertatis obliti, alterum suæ: the sum of behaviour is to retain a man’s own dignity, without intruding upon the liberty of others. On the other side, if behaviour and outward carriage be intended too much, first it may pass into affectation, and then Quid deformius quam scenam in vitam transferre—to act a man’s life? But although it proceed not to that extreme, yet it consumeth time, and employeth the mind too much.” source
