The intention behind Edmund Husserl's last work leaves no doubt that the development of phenomenological philosophy is consistent with the retention of the methodological purity. According to static analysis, the transcendental legitimization of this objectivity and transcendency is accomplished when the constitution of the intersubjective availability of the objective world, which is inseparable from its very meaning as objective, is accounted for. The eidetic investigation of functioning transcendental subjectivity encounters what Husserl calls the 'paradox of human subjectivity' if it is guided by what he characterizes as the naivety of his own developmental approach to the world constituting functioning of subjectivity. In the Crisis texts Husserl clearly recognizes that the objective world's intersubjective availability has a deeper source than that of its genesis as an intentional modification of the concrete transcendental Ego, namely, its source in historicity.
