It is undoubtedly possible to hold that the position of transcendental idealism is not reached simply by using phenomenological reduction and by avoiding the error of petitio principii in epistemology. Sometimes it seems that even using this reduction it is possible to avoid the idealist solution but this solution is adopted only because, in carrying out the analysis of outer perception and the constitutive analysis (Betrachtung) certain decisions are made about various substantial matters that lead unavoidably to transcendental idealism in relation to the external world and even in relation to all transcendent objects.
