Søren Kierkegaard,
Works of LoveTo love one's neighbor means, while remaining within the earthly distinctions allotted to one, essentially to will to exist equally for every human being without exception . . .
Consider for a moment the world which lies before you in all it variegated multiplicity; it is like looking at a play, only the plot is vastly more complicated. Every individual in this innumerable throng is by his differences a particular something; he exhibits a definiteness but essentially he is something other than this -- but this we do not get to see here in life. Here we see only what role the individual plays and how he does it. It is like a play. But when the curtain falls, the one who played the king, and the one who played the beggar, and all the others -- they are all quite alike, all one and the same: actors. And when the death curtain falls on the stage of actuality . . . then they also are all one; they are human beings.
...The stage of art is like an enchanted world. But just suppose that some evening a common absent-mindedness confused all the actos so they thought they really were what they were representing. Would this not be, in contrast to the enchantment of art, what one might call the enchantment of an evil spirit, a bewitchment? ...the distinctions of earthly existence are only like an actor's costume or like a travelling cloak and that every individual should should watchfully and carefully keep the fastening cords of this outer garment loosely tied, never in obstinate knots, so that in the moment of transformation the garment can easily be cast off, and yet we all have enough knowledge of art to be offended if an actor, when he is supposed to cast off his disguise in the moment of transformation, runs out on the stage before getting the cords loose. But, alas, in actual life one laces the outer garment of distinction so tightly that it completely conceals the external character of this garment of distinction, and the inner glory of equality never, or very rarely, shines through, something it should do and ought to do constantly.
