If you read philosophical texts of the tradition, you'll notice they almost never said 'I,' and didn't speak in the first person. From Aristotle to Heidegger, they try to consider their own lives as something marginal or accidental. What was essential was their teaching and their thinking. Biography is something empirical and outside, and is considered an accident that isn't necessarily or essentially linked to the philosophical activity or system.
Jacques DerridaA text is not a text unless it hides from the first comer, from the first glance, the law of its composition and the rules of its game. A text remains, moreover, forever imperceptible. Its laws and rules are not, however, harbored in the inaccessibility of a secret; it is simply that they can never be booked, in the present, into anything that could rigorously be called a perception.

Jacques DerridaI believe in the value of the book, which keeps something irreplaceable, and in the necessity of fighting to secure its respect.
