Life Is A Warfare And A Stranger's

Purge Your Mind Of All Aimless And Idle Thoughts, Especially Those That Pry Into The Affairs Of Others Or Wish Them Ill.

Every Man's Life Lies Within The Present; For The Past Is Spent And Done With, And The Future Is Uncertain.

Look To The Essence Of A Thing, Whether It Be A Point Of Doctrine, Of Practice, Or Of Interpretation.

Do Not Act As If You Had A Thousand Years To Live.

From Apollonius I Learned Freedom Of Will And Undeviating Steadiness Of Purpose; And To Look To Nothing Else, Not Even For A Moment, Except To Reason.
