Context

“It is not in our power indeed to determine what the throw will be, but it is our part, if we are wise, to accept in a right spirit whatever fortune sends, and so to contrive matters that what we wish should do us most good, and what we do not wish should do us least harm. For those who live at random and without judgement, like those sickly people who can stand neither heat nor cold, are unduly elated by prosperity, and cast down by adversity; and in either case suffer from unrest, but 'tis their own fault, and perhaps they suffer most in what are called good circumstances. Theodorus, who was surnamed the Atheist, used to say that he held out arguments with his right hand, but his hearers received them with their left;” source
