Jean Piaget made an effort to balance these two points of view, which appeared to be at odds with the decades-long logical examination of happiness. Early in his clinical practice, Piaget created a special set of tests that revealed a connection between children's awareness, anxiety, and happiness. The critical consciousness of suffering, the misery of frustration, and the terror of uncertainty, according to Piaget, are among the things that adults do not want children to learn. Piaget's viewpoint was one that Sigmund Freud and Alfred Adler backed. Piaget contrasted the concepts that "Happiness" and "Anxiety" are derived from, which originate in childhood, are meaningless, and date back to classical Greece, with "critical consciousness," which is the foundation of modern critical psychology.
