The Thinking (person) Must Oppose

What Does Reverence For Life Say Abut The Relations Between [humanity] And The Animal World? Whenever I Injury Any Kind Of Life I Must Be Quite Certain That It Is Necessary. I Must Never Go Beyond The Unavoidable, Not Even In Apparently Insignificant Things. The Farmer Who Has Mowed Down A Thousand Flowers In His Meadow In Order To Feed His Cows Must Be Careful On His Way Home Not To Strike The Head Off A Single Flower By The Side Of The Road In Idle Amusement, For He Thereby Infringes On The Law Of Life Without Being Under The Pressure Of Necessity.

I Am Certain And Have Always Stressed That The Destination Of Mankind Is To Become More And More Humane. The Ideal Of Humanity Has To Be Revived.

Train Yourself Never To Put Off The Word Or Action For The Expression Of Gratitude.

One Who Gains Strength By Overcoming Obstacles Possesses The Only Strength Which Can Overcome Adversity.

But Merely Accepting Authoritarian Truth, Even If That Truth Has Some Virtue, Does Not Bring Skepticism To An End. To Blindly Accept A Truth One Has Never Reflected Upon Retards The Advance Of Reason. Our World Rots In Deceit. . . . Just As A Tree Bears The Same Fruit Year After Year And At The Same Time Fruit That Is New Each Year, So Must All Permanently Valuable Ideas Be Continually Created Anew In Thought. But Our Age Pretends To Make A Sterile Tree Bear Fruit By Tying Fruits Of Truth Onto Its Branches.
