“Mental health cannot be defined in terms of the "adjustment" of the individual to his society, but, on the other hand, that it must be defined in terms of the society to the needs of man, of its role in furthering or hindering the development of mental health. Whether or not the individual is healthy, is primarily not an individual matter, but depends on the structure of his society.”
― Erich Fromm, The Sane Society
