Every discourse, even a poetic or oracular sentence, carries with it a system of rules for producing analogous things and thus an outline of methodology.
Jacques DerridaIf 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 DerridaThe poetโฆis the man of metaphor: while the philosopher is interested only in the truth of meaning, beyond even signs and names, and the sophist manipulates empty signsโฆthe poet plays on the multiplicity of signifieds.
