"We're not given a method for dealing with philosophical texts and essays. We don't know what it means to study or comment on a philosophical text, or even to write an essay", complain baccalaureate candidates and even university students. In fact, this philosophical methodology book is designed to help baccalaureate holders and students do a good job in this area, enabling them to better approach a (philosophical) text, an essay and/or a commentary on a philosophical text.In order to present a detailed plan of the work, we first discuss the explanation or study of a text. We will refer to the various possible explanations and lines of thought on the different questions often asked in the Haitian bac, with a view to providing baccalaureates with new techniques. We will then look at text models and suggest practical exercises. Then we'll move on to the philosophical essay, which for most candidates and students is a mystery or magic. Finally, we'll look at the philosophical text commentary.
