A hint of Rogerian humanism in the work of Charles Fourier:

According to Fourier, all instincts are equally fruitful and useful for society it is only necessary to combine them and direct them in the proper way: "There is not a single useless or bad passion; all personalities are good as they are." (97: p. 292) "Passions, whatever they might be even the most repulsive both in man and in animals, lead to their various consequences according to geometrical principles observed by God." (97: p. 60) As a result, citizens who are most useful to the societal mechanism are those "who are most inclined to refined pleasures and who boldly give themselves up to the satisfaction of their passions." (97: p. 292) The future "combined" social structure is built along the same lines: "In the eighteen communities of the combined structure, the trait that is the most useful for the triumph of truth is love of wealth." (97: p. 95) "The whole arrangement of the combined structure will be the direct opposite of our habits and will compel the encouragement of everything we call vice, for instance, the passion for sweets and the pleasures of love." (97: p. 96)

In The Socialist Phenomenon by Shafarevich

By Rogerian humanism I refer to the influential psychologist Carl Rogers who advanced the idea that all people have a profound inherent worth and that all of their emotions and feelings are valid.
