… is from page 203 of Anthony de Jasay’s brilliant 1998 volume, The State (original emphasis):
Envy is provoked by a person comparing his situation with the situation of certain others and perceiving inequalities. If one perceived inequality is eliminated, and the person is a comparing sort, his antennae are soon bound to make a half-turn and perceive another inequality (in terms of which he is “relatively deprived”), out of the countless ones which might catch his eye, because such scanning is inherent in his need to see his situation in relation to that of others – or else he is immune to envy.
