To Unlearn Is As Hard As To

Purpose ... Is Held To Be Most Closely Connected With Virtue, And To Be A Better Token Of Our Character Than Are Even Our Acts.

When We Deliberate It Is About Means And Not Ends.

Some Vices Miss What Is Right Because They Are Deficient, Others Because They Are Excessive, In Feelings Or In Actions, While Virtue Finds And Chooses The Mean.

The Investigation Of The Truth Is In One Way Hard, In Another Easy. An Indication Of This Is Found In The Fact That No One Is Able To Attain The Truth Adequately, While, On The Other Hand, No One Fails Entirely, But Everyone Says Something True About The Nature Of All Things, And While Individually They Contribute Little Or Nothing To The Truth, By The Union Of All A Considerable Amount Is Amassed.

Excellence Or Virtue Is A Settled Disposition Of The Mind That Determines Our Choice Of Actions And Emotions And Consists Essentially In Observing The Mean Relative To Us ... A Mean Between Two Vices, That Which Depends On Excess And That Which Depends On Defect.
