Critical discourse analysis (CDA) represents one of the areas of increasing importance in various human fields as the fields of discourse analysis have recently included fields of literature, culture, politics and even health and education. There are many approaches to the study and analysis of discourse, including linguistic, social, philosophical, and other approaches. Rhetoric is the art of good speech. It is latent in writing and speaking persuasively. Its aim is to inform, educate, persuade or motivate specific audiences in specific situations. Since rhetoric has a close relationship with the literary text in its various manifestations and its artistic, literary and analytical formations, the critical and rhetorical discourse has witnessed a remarkable development in the field of linguistics in general and discourse analysis in particular. The present study attempts to illustrate the value of the rhetorical discourse through exploring the persuasive strategies and linguistic devices used by Ursula Von der Leyen's speech on Europe's digital future. Through the study, the researcher tries to shed light on the cultural change and cognitive progress in light of digitalization age. The five principles of rhetoric: invention, arrangement, style, delivery, and memory will be explored for the analysis of the chosen speech. Rhetorical Structure theory (RST) as developed by Bill Mann in 2000 and William C. Mann in 2006 within the field of computational linguistics has been employed for proving the relationship between text organization and showing the effectiveness of the rhetorical and critical discourse, and hence showing the scientific and technological progress in the age of digitalization.
