Child and Adolescent Psychology
(Psychologia dla osób posiadających wyższe wykształcenie)

Unlike the physicist, the psychologist … investigates processes that belong to the same order — perception, learning, thinking — as those by which he conducts his investigation.

Psychology has a long past, but only a short history.

[Modern psychology] appears as the sickly offspring of average common sense when it is taken as what it professes to be—a science of the inner life. The entire achievements of the so-called science in this respect is outweighed by a single page of Goethe’s or of Jean Paul’s psychology; and it is impossible to evade the bitter truth which Novalis already has summed up, when he says that so-called psychology is one of those idols which have usurped the place in the sanctuary where true images of the gods should stand.
