Husserl, Edmund. Ideas Pertaining to a Pure Phenomenology and to a Phenomenological Philosophy: First Book. Translated by Fred Kersten. The Hague: Martinus Nijhoff, 1982.
Pure phenomenology, to which we are here seeking the way, whose unique position in regard to all other sciences we wish to make clear, and to set forth as the most fundamental region of philosophy, is an essentially new science, which in virtue of its own governing peculiarity lies far removed from our ordinary thing, and has not until our own day therefore shown an impulse to develop. p.37 Gibson translation.
