text: If you were ill, you would stop caring for your personal concerns, and forget your business duties; you would not think highly enough of any client to take active charge of his case during a slight abatement of your sufferings. You would try your hardest to be rid of the illness as soon as possible. What, then? Shall you not do the same thing now? Throw aside all hindrances and give up your time to getting a sound mind; for no man can attain it if he is engrossed in other matters. Philosophy wields her own authority; she appoints her own time and does not allow it to be appointed for her. She is not a thing to be followed at odd times, but a subject for daily practice; she is mistress, and she commands our attendance. Alexander, when a certain state promised him a part of its territory and half its entire property, replied: "I invaded Asia with the intention, not of accepting what you might give, but of allowing you to keep what I might leave." Philosophy likewise keeps saying to all occupations: "I do not intend to accept the time which you have left over, but I shall allow you to keep what I myself shall leave."
