Science is not naive knowledge in the theoretical interest; rather, to its essence there belongs from now on a certain critique a critique based on principle, a critique which justifies every step of the knowing activity through principles/' which at every step involves the consciousness that any step of such a form is necessarily a correct one, that in this way the path of cognitive grounding, of the progress of that which grounds and that which is grounded upon it, is a correct path aimed at the goal, so that the resulting knowledge is a genuine knowledge and that the being known is not merely supposed vermeintes but known in the pregnant sense, true being itself, exhibiting its legitimacy in the knowledge itself.
