It is well known that the perception of reality may be disturbed by a 'repression' of the awareness of one's own characteristics, followed by an ability to see these characteristics in others, as well as by 'projection', which makes one see things in others which one dislikes being aware of in one's self. Weiss stresses the point that a projection is also based on the correct perception of the feelings or moods of other persons by way of 'empathy'. He investigates this 'objectiveness' of one's own attitudes, which makes the understanding of others possible, and inquires into its failure when the relation of a person to his own attitude is disturbed. He explains such 'objectivation' by the example of the understanding of children by adults (everybody was once a child), and of the mutual understanding of the sexes (every man has feminine traits, and every woman masculine ones). The decisive question concerning the correctness of judgments about other persons is not dealt with.
