An introduction to this work considers three sentences beginning with “I will keep my weapon.” This work’s first section contrasts someone who gains satisfaction from spreading joy with someone who becomes charitable after overcoming immense sorrow; that section of this work opens with the claim that the only thing with unconditional worth is “a good will.” The end of this work imagines a place where people conduct themselves “according to maxims of freedom as if they were laws of nature.” (10[1])A “supreme principle” introduced in this work, (-5[1])which requires humans to never be treated as a means to an end, (-5[1])is expanded on in the author’s later works, like the second edition of Critique of Pure Reason. For 10 points, the categorical imperative was introduced in what work on ethics by Immanuel Kant? ■END■ (0[3])
