Beneficence Is A Duty.

I Assert That, In Any Particular Natural Science, One Encounters Genuine Scientific Substance Only To The Extent That Mathematics Is Present.

I Learned To Honor Human Beings, And I Would Find Myself Far More Useless Than The Common Laborer If I Did Not Believe That This Consideration Could Impart To All Others A Value Establishing The Rights Of Humanity.

Beneficence Is A Duty; And He Who Frequently Practices It, And Sees His Benevolent Intentions Realized Comes, At Length, Really To Love Him To Whom He Has Done Good.

I Have No Knowledge Of Myself As I Am, But Merely As I Appear To Myself.

Animals... Are There Merely As A Means To An End. That End Is Man.
