Aristotle, Nicomachean Ethics
H. Rackham, Ed.

Now the following opinions are held: （a） that Self-restraint and Endurance are good and praiseworthy dispositions, Unrestraint and Softness bad and blameworthy; （b） that the self-restrained man is the man who abides by the results of his calculations, the unrestrained, one who readily abandons the conclusion he has reached; （c） that the unrestrained man does things that he knows to be evil, under the influence of passion, whereas the self-restrained man, knowing that his desires are evil, refuses to follow them on principle; （d） that the temperate man is always self-restrained and enduring; but that the converse is invariably the case some deny, although others affirm it: the latter identify the unrestrained with the profligate and the profligate with the unrestrained promiscuously, the former distinguish between them.
