The Detective Who Misled in His Own Method

In this thesis I analyze detective Sherlock Holmes method based on the semiotics of Ch. S. Peirce. I would like to show that although Holmes detective about his method claim that it is deductive, in-depth analysis shows that this method is far more complex and involves induction and abduction, and that each of these methods has its own importance in the detective's reasoning. The work is divided into three parts. The first part focuses on the Sherlock Holmes detective in terms of logical methods. The second part is focused on methods of reasoning by Ch. S. Peirce emphasizing abduction, a hypothesis. The third part is practical and includes analysis of the process of detective Sherlock Holmes based on the thesis of Ch. S. Peirce, as outlined in the second part.
