Enough now of absurd theories. No conceivable theory can make us err with respect to the principle of all principles: that every originary presentive intuition is a legitimizing source of cognition, that everything originarily (so to speak in its “personal actuality”) offered to us in “intuition” is to be accepted simply as what it is presented as being, but also only within the limits in which it is presented there.
— Husserl, Ideas I, §24
