What’s the difference between knowledge and wisdom?
They aren’t heterogeneous, and you can know lots of things and have no wisdom at all. Between knowledge and action there is an abyss, but that abyss shouldn’t prevent us from trying to know as much as possible before making a decision. Philosophy is the love of wisdom. Philia is love and sophia is wisdom, so the duty to be wise is what philosophy is. Nonetheless, decisions don’t depend exclusively on knowledge. I try to know as much as possible before making a decision, but I know that at the moment of the decision I’ll make a leap beyond knowledge.

What’s the most widely held misconception about you and your work?
That I’m a skeptical nihilist who doesn’t believe in anything, who thinks nothing has meaning, and text has no meaning. That’s stupid and utterly wrong, and only people who haven’t read me say this. It’s a misreading of my work that began 35 years ago, and it’s difficult to destroy. I never said everything is linguistic and we’re enclosed in language. In fact, I say the opposite, and the deconstruction of logocentrism was conceived to dismantle precisely this philosophy for which everything is language. Anyone who reads my work with attention understands that I insist on affirmation and faith, and that I’m full of respect for the texts I read.
