The article discusses the issue of proper names defined as symptoms of culture. The first part is of a theoretical character and develops the theory of symptomatology of culture in the context of semiotics (Ch. Peirce), psychology and psychoanalysis (S. Freud and J. Lacan), and onomastics. Symptomatology of culture is a practice of interpreting a certain group of texts of culture and extracting common qualitative traits within them. This is especially in the case of those traits specific to them and often encountered, which could testify to particular serious and deeply-rooted social phenomena leading to their appearance. In the empirical part the author presents a way of using (onymic) symptomatology in practice to research modern culture. She uses the examples of popular psychological and auto-therapeutic guidebooks and treats them as linguistic symptomatic forms of the most significant linguistic and cultural phenomena along with their social causes and functions which are often dysfunctional or abnormal in character. The analysis comprises the most typical conceptual and syntactic constructions encountered in the group.
