It is impossible to live a pleasant life without living wisely and honorably and justly, and it is impossible to live wisely and honorably and justly without living pleasantly. Whenever any one of these is lacking, when, for instance, the man is not able to live wisely, though he lives honorably and justly, it is impossible for him to live a pleasant life.
EpicurusHe who understands the limits of life knows that it is easy to obtain that which removes the pain of want and makes the whole of life complete and perfect. Thus he has no longer any need of things which involve struggle.
