Thus, then, have I evolved for myself the "free spirits" to whom this discouraging-encouraging work, under the general title "Human, All Too Human," is dedicated. Such "free spirits" do not really exist and never did exist. But I stood in need of them, as I have pointed out, in order that some good might be mixed with my evils (illness, loneliness, strangeness, acedia, incapacity): to serve as gay spirits and comrades, with whom one may talk and laugh when one is disposed to talk and laugh, and whom one may send to the devil when they grow wearisome. They are some compensation for the lack of friends.
