You can define our highest good in different ways. The same idea can be expressed with different words. Think of an army. Sometimes it spreads out wide. Sometimes it bunches together. Sometimes it curves at the wings when the center pulls back. Sometimes it forms a straight line. No matter what shape it takes, its strength and loyalty stay the same. Our definition of the highest good works the same way. Sometimes you express it with many words. Sometimes you say it briefly. Both ways mean the same thing. I could say 'The highest good is a mind that ignores fortune's accidents and finds joy in virtue.' Or I could say 'It is an unbeatable strength of mind that knows the world well, acts gently, and shows great courtesy to everyone it meets.' Same idea, different words.
Our highest good may also be defined otherwise, that is to say, the same idea may be expressed in different language. Just as the same army may at one time be extended more widely, at another contracted into a smaller compass, and may either be curved towards the wings by a depression in the line of the centre, or drawn up in a straight line, while, in whatever figure it be arrayed, its strength and loyalty remain unchanged; so also our definition of the highest good may in some cases be expressed diffusely and at great length, while in others it is put into a short and concise form. Thus, it will come to the same thing, if I say "The highest good is a mind which despises the accidents of fortune, and takes pleasure in virtue": or, "It is an unconquerable strength of mind, knowing the world well, gentle in its dealings, showing great courtesy and consideration for those with whom it is brought into contact."
