What is that which as to this material (our life) can be done or said in the way most conformable to reason. For whatever this may be, it is in thy power to do it or to say it, and do not make excuses that thou art hindered. Thou wilt not cease to lament till thy mind is in such a condition that, what luxury is to those who enjoy pleasure, such shall be to thee, in the matter which is subjected and presented to thee, the doing of the things which are conformable to man's constitution; for a man ought to consider as an enjoyment everything which it is in his power to do according to his own nature. And it is in his power everywhere.
