““man’s dignity consists in the following facts which distinguish man from animals. First, that he has a playful curiosity and a natural genius for exploring knowledge; second, that he has dreams and a lofty idealism (often vague, or confused, or cocky, it is true, but nevertheless worthwhile); third, and still more important, that he is able to correct his dreams by a sense of humor, and thus restrain his idealism by a more robust and healthy realism; and finally, that he does not react to surroundings mechanically and uniformly as animals do, but possesses the ability and the freedom to determine his own reactions and to change surroundings at his will.””
