“In provisionally characterizing the object which serves as the theme of our investigation (the Being of entities, or the meaning of Being in general), it seems that we have also delineated the method to be employed. The task of ontology is to explain Being itself and to make the Being of entities stand out in full relief. And the method of ontology remains questionable in the highest degree as long as we merely consult those ontologies which have come down to us historically, or other essays of that character. Since the term "ontology" is used in this investigation in a sense which is formally broad, any attempt to clarify the method of ontology by tracing its history is automatically ruled out. When, moreover, we use the term "ontology," we are not talking about some definite philosophical discipline standing in interconnection with the others. Here one does not have to measure up to the tasks of some discipline that has been presented beforehand; on the contrary, only in terms of the objective necessities of definite questions and the kind of treatment which the 'things themselves' require, can one develop such a discipline. With the question of the meaning of Being, our investigation comes up against the fundamental question of philosophy. This is one that must be treated *phenomenologically*. Thus our treatise does not subscribe to a 'standpoint' or represent any special 'direction'; for phenomenology is nothing of either sort, nor can it become so as long as it understands itself. The expression 'phenomenology' signifies primarily a *methodological conception*. This expression does not characterize the what of the objects of philosophical research as subject-matter, but rather the *how* of that research. The more genuinely a methodological concept is worked out and the more comprehensively it determines the principles on which a science is to be conducted, all the more primordially is it rooted in the way we come to terms with the things themselves, and the farther is it removed from what we call "technical devices," though there are many such devices even in the theoretical disciplines. Thus the term 'phenomenology' expresses a maxim which can be formulated as 'To the things themselves!' It is opposed to all free-floating constructions and accidental findings; it is opposed to taking over any conceptions which only seem to have been demonstrated; it is opposed to those pseudo-questions which parade themselves as 'problems', often for generations at a time. Yet this maxim, one may rejoin, is abundantly self-evident, and it expresses, moreover, the underlying principle of any scientific knowledge whatsoever. Why should anything so self-evident be taken up explicitly in giving a title to a branch of research? In point of fact, the issue here is a kind of 'self-evidence' which we should like to bring closer to us, so far as it is important to do so in casting light upon the procedure of our treatise. We shall expound only the preliminary conception [Vorbegriff] of phenomenology. This expression has two components: "phenomenon" and "logos." Both of these go back to terms from the Greek: φαινόμενον and λόγος. Taken superficially, the term "phenomenology" is formed like "theology," "biology," "sociology"―names which may be translated as "science of God," "science of life," "science of society." This would make phenomenology the *science of phenomena*. We shall set forth the preliminary conception of phenomenology by characterizing what one has in mind in the term's two components, 'phenomenon' and 'logos', and by establishing the meaning of the name in which these are *put together*. The history of the word itself, which presumably arose in the Wolffian school, is here of no significance."―from_Being and Time_. Translated by John Macquarrie & Edward Robinson, pp. 49-51”
