“The average person appreciates a value only “in the course of, and through comparison” with the possessions, condition, plight or quality of other persons. … The awareness that the acquisition and enjoyment of that value is beyond the person’s capacity … triggers two mutually opposite, but equally vigorous reactions: an overwhelming desire (all the more tormenting because of the suspicion that it might be impossible to fulfill); and ressentiment—a rancor caused by a desperate urge to ward off self-deprecation and self-contempt by demeaning, deriding and degrading the value in question, together with its possessors.”

Context: Courage is not a virtue of value among other personal values like love or fidelity. It is the foundation that underlies and gives reality to all other virtues and personal values. Without courage our love pales into mere dependency. Without courage our fidelity becomes conformism.

Variant: The man of ressentiment cannot justify or even understand his own existence and sense of life in terms of positive values such as power, health, beauty, freedom, and independence. Weakness, fear, anxiety, and a slavish disposition prevent him from obtaining them. Therefore he comes to feel that “all this is vain anyway” and that salvation lies in the opposite phenomena: poverty, suffering, illness, and death. This “sublime revenge” of ressentiment (in Nietzsche’s words) has indeed played a creative role in the history of value systems. It is “sublime,” for the impulses of revenge against those who are strong, healthy, rich, or handsome now disappear entirely. Ressentiment has brought deliverance from the inner torment of these affects. Once the sense of values has shifted and the new judgments have spread, such people cease to been viable, hateful, and worthy of revenge. They are unfortunate and to be pitied, for they are beset with “evils.” Their sight now awakens feelings of gentleness, pity, and commiseration. When the reversal of values comes to dominate accepted morality and is invested with the power of the ruling ethos, it is transmitted by tradition, suggestion, and education to those who are endowed with the seemingly devaluated qualities. They are struck with a “bad conscience” and secretly condemn themselves. The “slaves,” as Nietzsche says, infect the “masters.” Ressentiment man, on the other hand, now feels “good,” “pure,” and “human”—at least in the conscious layers of his mind. He is delivered from hatred, from the tormenting desire of an impossible revenge, though deep down his poisoned sense of life and the true values may still shine through the illusory ones. There is no more calumny, no more defamation of particular persons or things. The systematic perversion and reinterpretation of the values themselves is much more effective than the “slandering” of persons or the falsification of the world view could ever be.

Context: The writer has developed a “dynamical” approach to the study of cooperative games based upon reduction to non-cooperative form. One proceeds by constructing a model of the preplay negotiation so that the steps of negotiation become moves in a larger non-cooperative game [which will have an infinity of pure strategies] describing the total situation. This larger game is then treated in terms of the theory of this paper [extended to infinite games] and if values are obtained they are taken as the values of the cooperative game. Thus the problem of analyzing a cooperative game becomes the problem of obtaining a suitable, and convincing, non-cooperative model for the negotiation.
The writer has, by such a treatment, obtained values for all finite two-person cooperative games, and some special n-person games.
