The meaning of philosophy demands that he who philosophizes must do it radically. The radical attitude consists in the destruction of the presupposition of a world existing independently of us. It is this destruction which leads to the ideal of "presuppositionlessness" (Voraussetzungslosigkeit). Such a radical reflection comes very near to a sceptical one in such a way that the statement "the world is" is my statement. Thus, Husserl in search of his "first philosophy" takes into account the radicality of the sceptical attitude. Husserl is transcendent ally motivated in his praise of Humean sceptical attitude.
