“Go ahead and conclude whatever you want; just remember that all of your conclusions, every single one of them, may need to be corrected.” This attitude does not require you to renounce knowledge. It requires you only to renounce certainty, which is not the same thing. In other words, your knowledge is always tentative and subject to correction. At the bottom of this kind of skepticism is a simple proposition: we must all take seriously the idea that any and all of us might, at any time, be wrong.
