Main lines of investigation
In the research field, the Book of Disquiet has been the object of analysis, either because of its composition or because of the content of the fragments that can be integrated into it.
There are critics who consider the book a laboratory of heteronimity, that is, a space for essay and confluence of the issues of identity, drama, multiplicity and unfolding.
There are also studies related to philosophy and the analysis of sensations in Bernardo Soares, as well as studies on the differences between Vicente Guedes and Bernardo Soares.
The role of Lisbon as a main character of the Book is also noteworthy.
Geocriticism, gender issues, intertextual relations, the spatial and temporal landscape are other topics most often put into analysis.
