The course of History of Philosophy I aims at being an introduction to the main problems of philosophical thinking, deepening on the basic assumptions that support it. It is therefore necessary to address the origins of philosophy and look into its first developments: because every philosophy constitutes already a way of dialogue with the philosophical tradition. The student thus acquires not only the basic methodological tools necessary for the understanding of classic texts, but also and above all, the ability to connect philosophical problems with the base from where they arose, in addition to acquiring a holistic view of the problems of philosophical thought from their origin. One will learn to critically read texts, to properly interpret, analyse and connect them to their ultimate sources. An indispensable philosophical foundation will be acquired to understand the development of philosophy, providing the student with basic philosophical vocabulary.
