1 " We must consider also whether soul is divisible or is without parts, and whether it is everywhere homogeneous or not; and if not homogeneous, whether its various forms are different specifically or generically; up to the present time those who have discussed and investigated soul seem to have confined themselves to the human soul. We must be careful not to ignore the question whether soul can be defined in a single account, as is the case with animal, or whether we must not give a separate account of each sort of it, as we do for horse, dog, man, god (in the latter case the universal, animal—and so too every other common predicate—is either nothing or posterior). Further, if what exists is not a plurality of souls, but a plurality of parts of one soul, which ought we to investigate first, the whole soul or its parts? It is also a difficult problem to decide which of these parts are in nature distinct from one another. Again, which ought we to investigate first, these parts or their functions, mind or thinking, the faculty or the act of sensation, and so on? If the investigation of the functions precedes that of the parts, the further question suggests itself: ought we not before either to consider the correlative objects, e.g. of sense or thought? It seems not only useful for the discovery of the causes of the incidental proprieties of substances to be acquainted with the essential nature of those substances (as in mathematics it is useful for the understanding of the property of the equality of the interior angles of a triangle to two right angles to know the essential nature of the straight and the curved or of the line and (the plane) but also conversely, for the knowledge of the essential nature of a substance is largely promoted by an acquaintance with its properties: for, when we are able to give an account conformable to experience of all or most of the properties of a substance, we shall be in the most favourable position to say something worth saying about the essential nature of that subject: in all demonstration a definition of the essence is required as a starting point, so that definitions which do not enable us to discover the incidental properties, or which fail to facilitate even a conjecture about them, must obviously, one and all, be dialectical and futile." —from_On the Soul: Book I_ "

4 " As a method however, the *method of ontology* is nothing but the sequence of the steps involved in the approach to Being as such and the elaboration of its structures. We call this method of ontology *phenomenology*. In more precise language, phenomenological investigation is explicit effort applied to the method of ontology. However, such endeavors, their success or failure, depend primarily, in accordance with our discussion, on how far phenomenology has assured for itself the object of philosophy―how far, in accordance with its own principle, it is unbiased enough in the face of what the things themselves demand. We cannot now enter any further into the essential and fundamental constituent parts of this method. In fact, we have applied it constantly. What we would have to do would be merely to go over the course already pursued, but now with explicit reflection on it. But what is most essential is first of all to have traversed the whole path once, so as, for one thing, to learn to wonder scientifically about the mystery of things and, for another, to banish all illusions, which settle down and nest with particular stubbornness precisely in philosophy.There is no such thing as *the one* phenomenology, and if there could be such a thing it would never become anything like a philosophical technique. For implicit in the essential nature of all genuine method as a path toward the disclosure of objects is the tendency to order itself always toward that which it itself discloses. When a method is genuine and provides access to the objects, it is precisely then that the progress made by following it and the growing originality of the disclosure will cause the very method that was used to become necessarily obsolete. The only thing that is truly new in science and in philosophy is the genuine questioning and struggle with things which is at the service of this questioning." ―from_The Basic Problems of Phenomenology_ "
