Intellectuals, academicians, and critics alike do not miss the opportunity to tackle Sherlock Holmes’s proficiency as one-of-a-kind consulting detective created in the stories of the Scottish writer, Sir Arthur Conan Doyle (1859-1930). A closer look into Doyle’s literary works points to the path of the author’s visionary outlook, in terms of Holmes’ philosophy and investigation methods, which this paper argues, resonate with the core technology of the modern era. Central to the theme surrounding the Holmesian doctrine, this research takes inspiration from the “ability of the mind” context with reference to the literary detective, Sherlock Holmes. The main objective is to elucidate that Holmes’ philosophy is not an outdated proposition. It is very much in circulation in modern investigation methods and applies to basic technological principles as well. Hence, its appeal is still relevant and connected to our lives today. In order to support the discourse and argument revolving Holmes’ philosophy, this paper adopts an analytical method that relies on contextual reference and textual inferences by comparing it with the contemporary narrative in terms of the emerging technology in today’s digital era. To provide Holmes’ worldwide fans with a deeper reading of his stories, this paper is not meant to present a thematic analysis of Doyle’s literary productions; rather it is a careful examination of Holmes’ mind. With a focus on Sherlock’s “ability of the mind,” the central hypothesis is approached by drawing analogies between his detective methods and the basic principles of computers and core technologies. In so doing, this research proves that Holmesian philosophy is still affecting a basic, yet forms a significant part of our lives in the twenty-first century.
