A City Is Composed Of Different Kinds

For It Is Owing To Their Wonder That Men Both Now Begin And At First Began To Philosophize... They Were Pursuing Science In Order To Know, And Not For Any Utilitarian End.

Let Us First Understand The Facts And Then We May Seek The Cause.

All Are Agreed That The Various Moral Qualities Are In A Sense Bestowed By Nature: We Are Just, And Capable Of Temperance, And Brave, And Possessed Of The Other Virtues From The Moment Of Our Birth. But Nevertheless We Expect To Find That True Goodness Is Something Different, And That The Virtues In The True Sense Come To Belong To Us In Another Way. For Even Children And Wild Animals Possess The Natural Dispositions, Yet Without Intelligence These May Manifestly Be Harmful.

In Practical Matters The End Is Not Mere Speculative Knowledge Of What Is To Be Done, But Rather The Doing Of It. It Is Not Enough To Know About Virtue, Then, But We Must Endeavor To Possess It, And To Use It, Or To Take Any Other Steps That May Make.

We Do Not Know A Truth Without Knowing Its Cause.
